The site above Tuti extends for over a 1 km with a number of concentrations of artifacts, providing a good test of the Arcpad system. The presence of chert nodules in the creek may be part of the reason for the size of this site. Because we're studying raw stone material coming out of a major obsidian source the presence of a site like this one close to the obsidian source providing chert, another type of raw material, is especially  interesting.
