My experience on Brushy falls into the category of "I hope I DONT find anything down this deep "
There was a gravely base in a calichie, yellow soil....definitely NOT a camp looking soil...BUT there was flint flakes in it..
On the lucky occasions we found anything interesting, it was primarily Martindale, one gorgeous Scottsbluff ( fairly rare in that area ) and one surprise HELL GAP ....I luv it
Bone fragments were white and heavy...well on their way to becoming fossilised.
Maybe I better come out and check your site personally tee hee
