Macrofloral and phytolith analysis was conducted on a sample of matting material recovered from the Eagle Point Site (5RB4662), a rockshelter/overhang located along Piceance Creek in northwest Colorado. This shelter experienced multiple occupations, with radiocarbon ages ranging from 2510 to 1010 BP. The roof/overhang has collapsed; therefore, cultural deposits are exposed and eroding away. Excavations at the site have been ongoing for several years. PRI has previously conducted archaeobotanical...

A ceramic vessel, recovered on the west side of Pikes Peak, Colorado exhibited charred residue on the interior. This residue was scraped off for microscopic analysis. In addition, a wash of the interior surface of the vessel under the residue was collected also for microscopic analysis. Microscopic analysis included a search for any pollen, phytoliths, or starches visible in the samples to provide evidence of foods that might have been cooked in the vessel.

Poverty Point Objects are "hand-molded backed clay cooking objects" (Gibson 1999:2). Because the area around Poverty Point contained few rocks, Poverty Point Objects are thought to have been used much like rocks that are heated and used to heat or boil foods in a container. Thirteen Poverty Point Objects and one steatite fragment were examined for pollen, phytoliths, and starches that might point to foods cooked using Poverty Point Objects as heat sources. In addition, two pollen samples...

The paleoenvironmental record at Lime Creek is composed of both pollen and phytolith data. Examination of the pollen and phytolith record is based on analysis of single pollen and phytolith samples per stratum yielding radiocarbon ages and three additional pollen samples. Sample selection paralleled sample selection for radiocarbon dates and geomorphic samples to maximize interpretability of these records. Samples spaced this far apart, of course, allow only a cursory examination of...

Very little evidence to reconstruct the paleoenvironment exists for this area of Wyoming. The paleoenvironment may be addressed through several different data bases, including the pollen and phytolith records, which are discussed here. A limited amount of stratigraphic pollen analysis has been completed in this area, from which the paleoenvironment may be interpreted, although no stratigraphic phytolith analysis has been undertaken for this area. Archaeological sites 48FR1468 and 48FR1602,...
