I have just about run out of material to knap. I have been scouring the interwebs for information on where in my fine state I can find knppable materials. For those of you who do collect your own stone, how did you find out about the location. I have found a lot of very vague information of where to look, but nothing concrete as of yet (besides for obsidian and chalcedony as more than just knappers are interested in it). For instance, there is a mention of an area called "Chert Canyon" in central Utah. That is where the information stops. I ran across a Doctoral dissertation last night. It was submitted to the University of Utah in 1970. I has a lot of useful information, but I still can't find any more mentions of the areas after the publication of this paper. So without boring you with the contents of the 96 page document here are my questions. How labor intensive is the collection of your materials. I am not afraid of some hard work, but I don't want to have to break trough 2 feet of limestone to get a few pounds of stone. Are you more likely to not disclose a good place to collect stone? The areas that I would be collecting are public lands. Most will require at least a 2 hour drive in each direction. Most are chock full of snakes this time of year. And then there is the issue with living in the desert. 100 degree plus temps and very little humidity. Thanks for all the help you all have given me on this quest. The bright side is the most promising area seems to have black chert.
