While resembling blades in the most generic sense (i.e., having parallel sides and a length more than twice that of the width), these flakes are not true blades and are easily distinguished from the true blades (or microblades) also found at the site. In terms of rockhounding, this is one of our favorite spots. While a few microblade cores have been found at CA-NAP-58 and at a few sites on Ritchey Creek and in Lake County, their relative paucity makes my proposed microblade technology extremely problematic.
