Made it to the creek today, put in a couple miles checking gravel beds and blowouts. No whole Buffalo heads but some good points and mongo sized knife. Biggest Washita I ever found, too bad about the impact fracture on the tip. There’s a pair here if you can see them both. One chert and one a red basalt like material. 10” apart as I found them. The red one is an odd type, beveled and fluted, I need to look it up. The gray one me and dad both have an exact match to it found within a half mile each direction. No idea how I spotted this before putting the window down for a look see in 2’ of stained water. Here it is all dried off.
