Tales of the Mojave: A Dry Placer

And now, let us continue with my Tales of the Mojave series. In our last post, we had barely left town—town being Reno, NV, hundreds of miles to the north, and we being Allie and I, two young and fairly junior geologists: I was beginning my fourth full year as an exploration geologist; Allie was beginning her first. Besides the several recon targets I had generated while we were still in Reno, we also had a placer submittal to examine and evaluate.

A Dime a Dozen


Placer claims are a dime a dozen in the Mojave, and they are typically worthless—at least in my limited experience. (Actual placer miners might disagree with my assessment, but I'm using the mindset of large, hard-rock mining and exploration companies.) Unlike lode mining claims, placer claims can be increased in size if an association (group of more than one person) locates the claim: The usual 20 acres per lode claim or individual placer claim can be as large as 160 acres in an association placer when located by 8 or more claimants.[1] Association placers can, in other words, cover an entire quarter section, making it possible to cover a lot of ground with relatively few claims, something that was done widely across the lowlands of the Mojave Desert of California in the 1980s (and elsewhere, like Arizona, and elsewhen, perhaps even right now). Many of the placer submittals we received during the 80s were located not only for gold, but also for platinum, an element that is quite rare in the placer settings of the southwestern deserts.
“A degree of skepticism should also be reserved for ores said to contain uncommon metals or minerals. Because of their rarity, these substances may command a very high price and are therefore extremely attractive to the investor. The platinum-group metals including platinum, palladium, rhodium, ruthenium, iridium, and osmium, are the darlings of the swindler. Considering their high unit-value, even minute amounts of these metals appear to be a reasonably good bet to the innocent investor.”
–from Mining Scams, AZGS
In any case, I’m not sure why we were called upon to appraise these particular placer claims, nor do I remember their exact location or size.[2] I did already know a few things about placer deposits—a little—having looked at a number of placer submittals in the California foothills earlier that year. The Mojave placer, however, was different from those in the Mother Lode region of California, being “a dry placer” or “desert placer,” which means they were not located on or very close to any actively running water. Flash floods in usually dry washes, and sheet runoff across the fans during storms had formed the sand and gravel deposits that might (or might not) contain placer gold, but the nearest naturally running water was several miles to the southeast in the Colorado River. (Water in the nearby Colorado River Aqueduct was nearer by half, but was inaccessible to any would-be placer operators, including us.[3])

The Desert Sun


The desert sun glared through the windshield of the truck as if to threaten us with heat stroke or worse, and heat waves rose inexorably from broad alluvial fans and bajadas, countless meandering dry washes, and endless desert pavement. As we turned onto dirt somewhere between Vidal Junction, CA, and Parker, AZ, I wondered what we were getting ourselves into. It wasn’t just the question of evaluating a dry placer property located miles from running water, but also the larger question: What were we doing in the Mojave in June? We drove down the fan, over rocks and by countless jumping cholla, not knowing for sure where we'd end up, not having to meet with the prospector, as one does so often when checking out a submittal. It didn't take long, really, before we found the spot, nearly lost in low, decapitated hills and erratic dry washes south of the Whipple Mountains, buried under  a millennium’s worth of accumulated sand and dust. Dust covers entire mountain ranges in the western Mojave Desert, and it collects on pool tables in towns up and down the Colorado River in the eastern Mojave. Parker, Arizona, is one of those towns. Hopefully we'll stop in Parker some other time.
We had brought extra water with us in 5-gallon containers, including 1 or 2 basic upright cooler types and several clear, collapsible plastic types. The extra water was, at this point, for evaluation of the claims, not for our own hydration, but the extra containers would serve us well as our expedition unfolded. So far we hadn't noticed anything untoward in the flavor of the water, primarily because we had filled our containers north of the NV-CA line, probably in Reno. Desert water can taste absolutely awful.

As property reviewers, we would not only have to determine whether gold was present, but we would have to make some deliberation as to the feasibility of mining by a fairly sizable company. I could think of three scenarios for processing (mining) any placer deposit we found:[4] 1) haul water into the area from the Colorado River or from Lake Havasu to wet-separate the heavy gold from the lighter quartz and feldspar sand and gravel, 2) haul the gold-bearing sand and gravel to the water, presumably the Colorado River, for wet-separation offsite (no doubt requiring further land acquisition), or 3) dry wash the sand and gravels without water. Dry washing using the oldtimers' dry winnowing method is notoriously inefficient at gold recovery and can be totally worthless if not done with extreme care and diligence.
How we get gold in California: winnowing gold, near Chinese camp.
Original in Harper's Monthly, v. 20, 1860; source: Library of Congress (no known restrictions).
Of course there are more current methods of dry washing available than winnowing, if you happen to have some gold-bearing sands and gravels on your Mojave placer claims. I'd look into the Bedrock Dreams website, which shows many possibilities and has a lot of info for the up-and-coming small-time gold miner (hard rock and placer).

The Dry Wash


At the dry wash, we camped in trenches dug by the claim holder. In the “cool” of the evening—when temperatures dropped somewhere between 70º and 85ºF by morning—we panned for gold using the precious water we had hauled in. Because the paved roads of Highways 95 and 62 and the desert-river town of Parker were not so far away, we went ahead and used a lot of our water for panning. We didn't have to save most of the water for drinking, which we would have done had we been camping four hours away—over hot, dusty roads—from anywhere of desert significance: any place with water, food, people, and, preferably, gas, spare parts, and tires (the latter preferences ruled out places like Goffs and Essex)

We were lucky, and our pans showed some color: a few, small flecks of gold almost too tiny to see. With repeated tries, we consistently got 2 to 4 colors in each pan. After we used up our extra water, which happened faster than we had envisioned, we took to dry panning. (It doesn't matter how close you are to town; it's ill-advised to use up all your water. You might need it during some unexpected, unplanned-for vehicle mishap or environmental disaster like a clogged fuel filter, a flat, a washed-out road, or a flash flood. See A Few Rules of the Desert.)

At some point, perhaps out of boredom, we gave up on classic dry panning, which looks a lot like regular panning but with tons of dust. One more time we filled the gold pan with the weakly gold-bearing alluvial sand and threw the material expectantly skyward. The evening breeze blew the lightweight fines toward Arizona—where all Mojave sand and dust aspires to reach—and the heavier material fell back toward the pan. We had reinvented dry winnowing! In theory, we should, after several skyward tosses of material, have been left with a few heavies, some black sand, and a few flecks of gold. We weren't, though; maybe our technique was subpar. Regular wet-wash gold panning requires some skill, but if there’s gold in the pan, even an unskilled person will usually find it—although I've seen newbies mistake golden-colored quartz, gold-flecked biotite, and that common mineral pyrite, AKA fool’s gold, for gold. All of these minerals might fool some of the people some of the time, though with practice or a good course in mineralogy, you should not get duped by any of them. Gold is the only mineral that will shine or look bright golden yellow in the shade. Pyrite pales next to gold, and put in the shade it won’t shine—it becomes just another mineral, barely tinted beyond pale brown, nowhere near the bright golden yellow of real gold. (The exact color of gold depends on its fineness and upon which of several other elements, notably Ag, Cu, Fe, Pt, Cd, might be contained within the gold. These factors will affect how bright yellow or golden the gold looks. And then there's chalcopyrite, not as common as pyrite, but often lying somewhere between pyrite and gold in it's yellow-gold sheen. So it is possible to be fooled. But don't be. A Niton™XL3t GOLDD+ xrf analyzer can be a friend.)

Dry panning and air winnowing hadn't done much besides create a lot of dust and two ravenous geologists. So we put the gold pans away and turned our thoughts toward dinner. The sun was fairly low over the Turtle Mountains to the northwest, and my time estimation method indicated we had about 1.5 hours to sunset. What should we eat? We went ahead and established our Mojave Desert, south-of-the-border-style cuisine of tacos or burritos, with avocado and as much hot salsa and jalapeño as we could stand. This type of food is not too heavy for the heat, and (I’ll swear to this—or ask any desert rat) the spicy burning of the peppers created a cooling effect, something we would really need as our time in the desert progressed. Besides, there’s enough vitamin C in the peppers to fight scurvy, a credible desert plague: Rapid melting of the ice will spoil many vegetables and a few fruits over the course of our stay.

Yeah, we had just arrived in the desert and were still greenhorns, not quite able to call ourselves Mojave Desert rats. Not yet.
A little fooling around with SunCalc produced this reproduction of sunrise and sunset at our campsite (approximate location and date).
As the sun sank behind the Mopah Peaks, I thought about the next day. We'd be moving upslope into the Whipple Mountains proper. We were done with the placer submittal and, back in Reno, would recommend “No Further Work.” Although we didn't really know how large the weakly gold-bearing sands are, we suspecedt that their likely flash-flood origin from upstream copper-gold diggings in the Whipples would make mapping out the gold bars and channels difficult at best.

Notes:


[1] (Read about basic claim location rules here.)

[2] In later years, when working for Former Mining Company, I rarely took on placer submittals; in fact I actively avoided them, especially after one particular submittal (a classic scam) led to a fabricated conflict between our lode claims and the association placer claims of the submitters.

[3] The Colorado River Aqueduct is a 242-mi (392 km) water conveyance in southern California. The aqueduct diverts water from the Colorado River at Lake Havasu (at Parker Dam north of Parker, AZ) on the California-Arizona border west across the Mojave Desert to the east side of the Santa Ana Mountains. The aqueduct is operated by the Metropolitan Water District of Southern California (MWD) as one of the primary sources of drinking water in southern California.

[4] A note about my usage of "found" and "deposit." We knew there were claims for placer gold. We didn't know for sure if any gold existed on the property or in the area. If there was gold in the dry washes, the claim owner had discovered it, not us. We, however, wouldn't think of any gold on the claims as an economic deposit until it had been tested, which usually involves drilling or—especially in the case of placers—small-scale test mining. It's not considered accurate to call a mineral occurrence a deposit until it meets economic parameters and passes mining feasibility studies. It is therefore correct for me to assert that the claim owner discovered the gold, but Northern Mining Company's representatives (us!) might discover a gold deposit.

The Roan Cliffs Again, This Time with Some Contacts

After seeing Ron Schott's awesome and enlightening GigaPan of the Roan Cliffs, I decided I had to mark some contacts on the photos from my last post (and partly because what I said or implied about the formations were a little off). To deduce the location of these contacts, I extrapolated from this USGS preliminary geologic map, using the USGS TNM 2.0 Viewer and Google Earth.
In the first photo, it's still a toss-up, imo, as to whether the Tertiary Uinta Formation (Tu) can be seen—but if so, it's way up at the top of the cliff. Most or all of the cliff and most of the slope is underlain by the Tertiary Green River Formation (Tg). Aaaaand maybe there's a bit of the Tertiary Wasatch Formation (Tw) at the bottom of the photo.
In the second photo, there is (probably) just a tiny bit of the lower part of the Uinta Formation (Tu) above the cliffy area, and the reddish-brown foreground slopes are underlain by the Wasatch Formation (Tw). The rest, cliff and slope, consists of Green River Formation (Tg).

From the Road: Bedding and Talus in the Roan Cliffs of Colorado

Getting back to my October-November road trip (last seen here), I stopped to get some fuel in Parachute, CO, on what was Day 7 of the trip, and I ended up taking a few photos (surprise!), partly thinking that the cliffs show good examples of bedding, and also because I was becoming fascinated by the exceptional talus slopes coming off the cliffs. The first photo is a cliff at a round nose sticking out from Mt. Callahan. The second photo is of a cliff at the southern end of a nose known as Allen Point, a long skinny ridge running about 1.5 miles south of a broader, arcuate area also called Allen Point.
When I investigated this area after my trip was over, I was surprised to find that these cliffs are part of the Roan Cliffs: while still enroute, I thought I was driving along the Book Cliffs. The Roan Cliffs are the cliffs that break south off of the broad Roan Plateau, a large plateau area that extends from Rifle, CO, to at least somewhere north of Grand Junction, possibly bounded on the west by Roan Creek. The Roan Cliffs, however, at least as shown here, encircle a broader area extending westward from Rifle, CO, to the mountains just east of the Wasatch in Utah.

The Roan Cliffs are capped by the Eocene Uintah Formation (which we may or may not see in these photos), and slopes below the uppermost cap are composed of the Eocene Green River Formation. Some of the lower, reddish slopes in the area are underlain by the Paleocene to Eocene Wasatch Formation. You can read a little more about the geology of the area in this USGS Bulletin.

The Roan Cliffs stratigraphically overlie the Book Cliffs, which we'll see later. I'm not sure how I mistook the cliffs of the Uintah Formation and upper Green River Formation for cliffs of the Cretaceous Mesaverde Group, or slopes of the Green River Formation for the usually easy-to-spot Cretaceous Mancos Shale. I can only plead that geology at 70+ mph isn't always spot-on.

Tales of the Mojave: A Bit About Northern Exploration Company

I planned to have this descriptive section as part of the last post—the one about being packed and ready to leave town—but this "little bit" grew and grew, and eventually it had to find its own home. I've written lots of little pieces like this; many of these could be hyperlinked from several main posts. This one might most properly go near the beginning of a Tales of the Mojave book.

N.E.C.


Northern Exploration Company (NEC), a famous former international mining and minerals exploration company, had seven exploration offices when I began working there as part of a small horde of young or “junior” geologists in NEC’s Western District. Some of us were temporary summer hands (and many of us, like me started that way); many of us were on year-to-year contracts (me!); and a very few of us ended up with permanent positions in the company. There were three or four permanent geos leading the horde when I began working there; that permanent cadre had expanded to maybe six by the time I left.

When not out in the field, we worked out of one of several office-warehouse complexes scattered here and there in Reno and Sparks.[1] The complexes seemed to have been slapdashed together and often had a few problems; for example, the typical southwest-desert–inspired flat roofs were prone to leak during storms or snow-melt. Our complex—and a nearby complex leased by another, also famous former mining company—was near the Truckee River and so occasionally flooded. The large windows of the office half of our complex faced south across a largely undeveloped area of the Truckee Meadows; these windows caused overheating, especially in winter when the low sun provided unplanned for solar energy. Nonetheless, we had a good setup that included a smallish warehouse in the back with shelves for field supplies, tables for core logging, and rock saws and grinding wheels for cutting and polishing hand samples.

The Western District of NEC was a decidedly renegade district, though at the time renegade attitudes were fairly common within exploration groups based out of Reno.[2] Geologists aren’t ordinarily known for their adherence to rules, and they are especially not known for following pointless and questionable rules sent down from above—an above that was usually either outside the country or east of the Mississippi, the latter being nearly the same thing as a foreign country to those born and bred in The West.


We can argue nearly forever about where The West begins or ends. The Mississippi River clearly constitutes one viable boundary for defining what is east and what is west. The hundredth meridian has also been used as the boundary between east and west; for example, in 1843, Thomas Farnham said lands between the 100th meridian and the Rockies were “usually called the Great American Desert” (Stegner, 1954). Later, Thomas Durant held a “100th Meridian Excursion” when Union Pacific crews passed the 100th meridian in 1866, a goal set by Congress. A little later, John Wesley Powell, writing for the USGS in 1879, recognized the 100th meridian as a line roughly defining the eastern boundary of his “Arid Region,” an area that generally receives less than 20 inches of rainfall per year and encompasses most of the west (by any definition). I think one could also use the Great Continental Divide as the boundary between east and west: All drainages east of the divide would drain to the Gulf of Mexico or the Atlantic. All drainages west of the divide would drain to the Pacific.
Google Earth image with yellow line marking part of the 100th meridian. The meridian cuts several states in two and roughly separates a greener area in the east from a notably browner area in the west.
I usually maintain that the true west, “The West” as I capitalized above, begins at the eastern edge of the Front Range of Colorado. Denver is not inside The West by this definition. (Neither is Boulder, for that matter.)


As mentioned in our main text above, geologists within the exploration offices of the west (however we define west) were often fractious and rebellious, and they were unlikely to listen to anyone from Chicago, say, some muckety-muck who might be sporting a fancy three-piece suit and polished black shoes. (There are numerous stories revolving around entertaining such VIPs.) Denver’s offices were often a little spiffier than those in Reno, perhaps having been influenced somewhat by the fancier petroleum offices in the area. Also, some Denver offices acted as headquarters for the minerals explorations groups of larger companies, and some *were* the headquarters for smaller companies. Consequently, geologists who had the misfortune to be based in Denver often ended up being a little more stilted, a little less rebellious, a little more formal: they were ever-so-noticeably more well-behaved when it came down to orders from above, and they were a little more likely to look at you askance if you decided that a rock-throwing contest was in order before the sampling program began in earnest. (A few were definite leaders as far as renegade actions go—here I’m particularly thinking of some unnamed few during my later years at Former Mining Company. Most, though—well, many—tried hard to keep up.)

The Kmart of Exploration


Our Hughes 500-D in 1978.
The Western District of NEC came to be known, at least to a select few, as “The Kmart of Exploration.” This appellation had been assigned to NEC by a summer hire[3] —Dan, the guy with the Frisbee dog, a black and white Aussie of one variety or another—during the uranium summer of 1979. He said he came up with the epithet after being involved in procuring supplies and provisions for the field largely at Kmart. I thought the nickname—seemingly indicating that the company was cheap—was overstated; after all, each uranium camp[4] had a trailer with space for a full kitchen; an office with drafting area, map storage cabinet, and beaucoup supplies; a camp cook; canvas tents with room for two field hands in each tent; a couple of 1978 4WD pickup trucks, brand new during the uranium summer of 1978; and a Hughes 500-D helicopter equipped with radiometric instruments capable of detecting radiation and breaking it down into the three major source elements, potassium (K), thorium (Th), and uranium (U). I thought our camps and equipment were pretty plush, especially when compared to the archaeological camps my husband frequented.

Much to the head honcho's dismay, "Kmart of Exploration" stuck. Perhaps it was partly our field schedule that made the name stick. We worked eleven and three, drive-on-your-own-time. That schedule meant eleven days in the field, three days off, with the driving time between home and field (and vice versa) being on our own time, not on paid-for company time. Perhaps the name stuck because we were encouraged, if not required, to camp out rather than stay in motels.

Camping supposedly saved gas, time, and money because we didn’t have to drive in to town every morning and evening and didn’t have to spend money on motel rooms. We also bought groceries instead of eating in restaurants, resulting in a lowered food expense. So we typically lived outdoors—in the dirt and weather of whatever area we were working in—for two to four nights; then we were into town for one night to get a shower, to sleep in a cool, air-conditioned motel room, to gas up, to stock up on fresh food, and—most importantly in the Mojave—to stock up on water and ice. Then, back into camp mode we went. I thought there were some flaws to the party line about camping, although I never did an actual cost-benefit analysis. For one thing, those of us who didn't have a permanent camp located somewhere near running water in the higher and cooler reaches of eastern Nevada (a certain lucky few that I was rarely part of) spent a certain amount of time setting up camp every evening. After getting our new camp in order, we made dinner and cleaned up. Then, nighty-night. After waking up in the morning, we tore everything down and repacked the back of the truck. With all the unpacking at night and repacking in the morning, we often ended up rearranging boxes of sample bags twice a day. Because we prepped our own camp and food daily, we were essentially working twelve to fourteen-hour days, rather than ten, with little time to rest or recoup in the evening before falling asleep (on cots or on the ground). Ten-hour field days were de rigueur at NEC. That meant we'd quit camp at 7:00 am, say, with breakfast and camp tear-down already complete, then work in the field until 5:00 pm. Then we'd finally get on to camp setup and dinner making after that. When someone else was cooking your meals and when there was running water available for cooling off and even showers, as in the uranium and moly camps, the hours were okay—long, but feasible.

In the Mojave, they were hell.

Notes:


[1] These complexes were often called "geo-ghettos" back then—although that term would probably not be politically correct now—often because they weren't built all that well in some respects, and also because they seemed to house a lot of geological groups.

[2] We cultivated—or were known for—a semi-outlaw attitude and everyday defiance that was deliberately exacerbated by the temperament of the head honcho in Reno.

[3] We didn’t call our summer employees “temps” until a good number of us moved to Forminco, where "temp" was already in use.

[4] For more about the uranium camps, see this series about the Caliente camp of the first uranium summer (that's what we called them: the first uranium summer, and the second uranium summer).

Tales of the Mojave: We're Almost Ready to Go

The Road South:


Our story—the 1981 story of Allie and I doing recon down in the Mojave—began in Reno in the spring of the year and ended unexpectedly and abruptly in Needles before the end of June. I no longer remember exactly how long we spent in the east-central Mojave, but we looked at six different target areas—depending on how you count them—and we probably spent at two to five days in each area.
"A beginning is the time for taking the most delicate care that the balances are correct. ...
- from 'Manual of Muad'Dib' by the Princess Irulan"


A Caravan Camper on a white truck
in front of a mine dump in eastern Nevada.
Allie and I left Reno in a dull gray, four-wheel drive Chevy pickup truck topped with a matching Caravan Camper, a type of heavy-duty metal camper shell with carpet kit, similar to the one I have now. We were equipped with an ice chest full of food, drinks, and ice; a 5-gallon water cooler or two; sundry camping gear; assorted tools; one spare tire (only one!); and all kinds of exploration equipment and supplies. We had sample bags and sample books, Estwing rock hammers and rock chisels, triplet hand lenses and little magnets on rawhide straps, and little plastic squeeze bottles filled with a 10% dilute solution of hydrochloric acid (HCl). The acid bottles were usually held tight in leather cases that could be slid onto belts. We also had a carefully stowed glass bottle of non-dilute HCl, so we could make additional dilute acid as needed. (HCl was easy to get back then, and the bottle came meticulously packed in vermiculite within a sturdy cardboard box.)

We had files of topographic maps, geologic maps, published reports, books, and copies of company reports in plastic file boxes that would help to keep everything organized while also protecting it from water and the pervasive Mojave dust. We had Brunton compasses in leather holders, ready to attach to our belts. And we had various mapping paraphernalia: mechanical pencils with black, blue, and red leads; colored pencils; pens and markers; and six-inch C-Thru® protractor-rulers of various scales: 10-50, 20-40, 10-20, and 30-60. We had field notebooks to hold notes and sketches, and we had aluminum clipboards that would protect our maps, air photos, and reports. We carried everything we needed for any particular day’s traverse in Filson® survey field vests[1], on belts, or in backpacks. A geologist, fully attired and field ready, is easily distinguished from desert rats, ranchers, and routine hikers.

We also had a pile of camping and cooking gear scattered in the back of the truck: pots and pans; plates, bowls, and utensils; a gas Coleman stove and fuel for said stove; sleeping bags and sleeping pads; a tent, which we didn't use while down in the Mojave; a tarp or two; and other miscellany. We may have rustled up some of the gear from a stash in the company warehouse—though had we not been timely in choosing gear (and we were late that year), we would have been out of luck. A certain person's name was used to describe what happened if you didn't grab your gear in time, or if you got stuck with second-rate supplies. Had his last name been Gibbs, it would have been called "getting Gibbsed." 
U.S. 95, looking south, just a few miles north of Beatty.
Before leaving Reno, we spent a little time pondering two particular questions: 1) should we take a thermometer and 2) should we abstain from beer and other alcohol? We debated back and forth about the thermometer and finally decided to leave it behind. Maybe we'd feel cooler if we didn’t see the expected 3-digit Fahrenheit temperatures!

If the creosote has bloomed, the field season is over.
Speaking of temperatures, when we got to our first locality, the temps we encountered didn't seem too bad, though it took a little time to adjust after coming from the higher and cooler elevations of Reno. We adapted. We devoured lots of fresh fruit. For lunch we’d have half avocados, their centers filled with Italian salad dressing, and we’d roll whatever else came out of the icebox in flour or corn tortillas.[2] We also prepared our own variant of south-of-the-border food, using lots of hot peppers, gobs of hot sauce, and unlimited spicy guacamole. We figured there would be something medicinal in mixing the spicy fire of the food with the scorching heat of the desert. And in fact, these were the only foodstuffs we could bring ourselves to eat in the heat. And throughout the day, from sunup to sundown, we drank gallons of water, juices, and sodas—and zero beers.

Notes:


[1] It looks like the standard survey vest isn't being made anymore—at least I don't see it on the C.C. Filson website. Perhaps that's because so many geos are now wearing safety vests much of the time. I hope my current beige style-12 and orange style-8 vests will last indefinitely: I still use them on field trips, while hiking, and on most sampling and mapping excursions. My beige vest is partly held together by duct tape; a gaping hole in the lower right area developed after carrying a leaky acid bottle inside the inner pocket. (I really don't like having things hanging from my belt, though I did used to wear my Brunton that way. Now I stick it in one of the side pockets.)

[2] This was called a "Bill Rehrig" lunch, although we didn't use that term until many years later.
