I happen to know about this little creek running under interstate 35 just north of Austin in Salado, TX - hint
. If you live within a 100 mile radius you better get there cause the pickens are good
. Apparently they had a flood down there last year and scrambled that creek up real good. I stopped in there a time or two before and knew there was flint but since the flood - damn! I'm finding a mix of perd, edwards, ameoba, Gtown lookin stuff - all kinds of stuff. I haven't been doing much knapping the last few years but still always collect when it's available. I have to say: This is the easiest picking I've ever done...
I don't think there's any kind of city ordinance there about picking minerals or anything (and it is right there in town) but I had a city cop drive by while I was hauling rock out and he waved his approval at me
, so I assume it's ok.
This stuff seems to spall and core pretty ok raw. A little heat wouldn't hurt but seems to work ok raw - good luck...
