Things You Find in the Field: Old Horseshoe

Recently, while out wandering in the desert two to three miles west of Humboldt House — formerly a resting area on the California trail and later a stage stop — I found this rusty horseshoe of unknown age.

A more traditionally "lucky" view of the horseshoe.

I have no idea how to discover the age of a rusty old horseshoe, and it looks like a fairly standard one to me, not that I'm really in the know.
