Basalt

Mike, andesite does occur around us? I thought for a while that what I had could be andesite, but couldn't find any in bedrock maps. I pretty much gave up on the railroad bed idea, the stuff was just too tough, maybe I'll come back to it. Still looking for a good rhyolite source close to me, but I found mention of a jasper outcrop in NH that I'm excited to check out.

I am not up on alot of sources but only know one from NH that is called Jasper. The outcrop is famous and spans use by paleo also. found northedge of the White Mtns along the dead river. Called Jasper Mtn it was excavated by Gramley back in 1976, and is basicly a flow banded rhyolite with a yellow color. The stuff was used heavily by all periods and I find it in N Maine even. Outcrops are completely dug out.
One way to find material to practice with is buy it from Or... there are rock sellers there that have new pits open and some very nice flaking material.

Right now I'm going by a local geologist's handbook. When I read jasper I was a bit skeptical since the only nearby outcrops I knew of were in PA, but the book is pretty old and has no mention of rhyolite, so I was pretty much hoping that he came across some higher quality rhyolite and didn't know what to call it. I've been pretty satisfied ordering obsidian from neolithics, but have been trying to switch to more local material to save money and get a feel for what the locals used. I've read a few things about Mt. jasper but never got to see any of the material, I know a paleo site that was dug in the 70's by me had some broken fluted points made from it. Think Berlin's something like a 5 hour drive from there, couldn't imagine walking.
