Comments
EcRi-1, Drynoch Slide: Cultural material in windblown sand resting directly on coarse gravel, presumably dates from an aggrading period of the Thompson River. A diagnostic feature of the cultural deposit is the presence of a microblade. GSC-530 consisted of a composite of numerous small pieces of charcoal scattered throughout a midden of fish remains and artifacts below Mazama ash. I-462 dates an extensive mud slide above Mazama tephra, and GSC-2056 dates a hearth feature within the head of the scarp that was utilized when the slide was relatively stable.
