Cowboy i got Say thanks, the value in any activity which involves just basic knowledge will help those of us who need to find sites or knowing the value of going into a creek and showing what types of rocks i need to look at increases the ability of all knappers. My feeling was that this part of this website was about imparting all aspects of knowledge involved in flint knapping from raw material, tools, how to heat rock and what are the results even if you show a picture of a badly heat rock. As little as some persons may think the little things are the foundations of the bigger pictures. I really want to learn and this site provides a media for me>
