I am headed to Colorado in September 2018 was going to keep an eye out for any chert, obsidian or flint. Are you aware of any rules regarding picking it up ?
there is no naturally occurring obsidian in CO. If it's here, it was hauled in..... No rules about picking up unworked chunks, but on public land you cannot pick up artifacts per the Antiquities Act. You can save artifacts on private property, tho. I am always on the lookout for arrowheads........
