Vent: I spent 3 years calling every burnt rock I dug up a cooking pit, and one soil sample from a site near Boise proved me dead wrong
I used to walk fields and creek banks looking for fire cracked rock, and the second I saw a cluster of it I wrote it down as a hearth. That went on for 3 years and about 40 sites, all logged in my notebook as cooking features. Last spring a friend talked me into paying $90 for a soil test on one of them, and the lab came back with almost no charcoal and no ash at all. Turns out those rocks were sitting on a old flood channel and got heated by nothing but sun and brush fires. I still feel dumb about how many write ups I sent in with "hearth" scribbled next to a pile of rocks in a dry wash. So how do you all decide when a rock cluster is really a fire feature before you bag it and log it?
