Summary

The Cassel-Fall River Road Bridge Replacement project along Pit River in Shasta County, California necessitated archaeological mitigation of site CA-SHA-3643-H located on the lower terrace on the east side of Pit River. Five basalt outcrops host seven mortar cups. Latestage obsidian and basalt debitage indicate tool production. A dense concentration of river mussel shells and calcined faunal remains were noted in the midden deposit. A radiocarbon date of 1720 cal. B.P. is reported on a gray-pine nut recovered from the midden. Obsidian hydration readings suggest Archaic occupations. Fire-cracked rock was recovered from Features 1 and 2 for organic residue analysis using Fourier Transform infrared Spectroscopy (FTIR) analysis.
