PSAL’s Geoprobe is a direct push coring rig that can recover intact sediment cores in 1.5 m intervals from subsurface contexts. We can use the Geoprobe to help build stratigraphic information about parts of sites and landscapes. Using the Geoprobe and information from the cores it can recover, PSAL works with clients to address questions of paleolandscape evolution, site formation, and site distribution in changing landscapes. By identifying and mapping the distribution of the “dirt of the right age” we can narrow down the search for particular kinds of archaeological sites.
