Full-Text
Pollen samples were collected from rock features at two sites in Rio Blanco County in northwestern Colorado. Located on a bench approximately 11 miles east of Rangely, these sites overlook the White River. Two features at each site were sampled for pollen. The features are described as concentrations of river-worn cobbles similar to agricultural features in Arizona. The purpose of pollen analysis at these sites was to search for evidence of agriculture.
