A Younger Dryas Pollen Spectrum from Blacktail Cave, Lewis and Clark County, Montana
Blacktail Cave, in the Northern Rocky Mountains of west central Montana, contains a lithostratigraphic and biotic record ranging from the middle Wisconsinan to the late Wisconsinan. It is in Lewis and Clark County, on the east side of the Continental Divide, within the drainage for the Dearborn River. AMS 14C dates on bone collagen from the deposit range from 37,000 to 10,000 RCYBP (Hill 2011). Four sediment samples form the Blacktail Cave sedimentary sequence were analyzed for pollen; a single sample contained pollen. Here we describe the pollen spectrum from this sample and its chronologic and stratigraphic context.
