Deposits within the Eagle Point Site (5RB4662), a rockshelter located along Piceance Creek in northwest Colorado, were sampled stratigraphically at close intervals for the purpose of building a detailed paleoenvironmental pollen record for this portion of Colorado. Although the sampling model called for sampling at approximately 2 cm intervals, the intervals collected varied because some levels were obviously unconsolidated and represented a single depositional, non-cultural event. In this...

Thirteen pollen and eight phytolith samples collected stratigraphically from sediments at CA-ORA-907 were examined to provide information necessary to reconstruct the past vegetation at the Talega site. The stratigraphic sediments reach a depth of. at least 61 feet, where a radiocarbon age of 14,980 ± 70 BP was obtained. Most of the sediments examined accumulated between approximately 15,000 BP and 8,000 BP and are anchored by one or more radiocarbon ages.

BA Cave is a small rockshelter located in the Bighorn Mountains containing a well-dated stratigraphic record covering the past 4000 years. Nine stratigraphic units were sampled and analyzed for pollen. It was hoped that the pollen record would illuminate differences in the source of the sediments in the strata and assist in interpreting the genetic origins of the sediments.

An alternating stratigraphic pollen column was excavated at Hell's Half Acre County Park, 40 miles west of Casper, Wyoming. Fifteen pollen samples, including a modern surface sample, were selected from the column, which represents stratified layers that include multiple occupations. Radiocarbon ages of 1920 ± 40 BP and 1970 ± 50 BP anchor the lowest occupation at a depth of approximately 112 cm, while an age of 1320 ± 80 BP ties in the upper occupation at a depth of 30 cm. Pollen analysis...

Pollen and macrofloral samples were examined from site 26Or3 for the Carson City Freeway project in Carson City, Nevada. Twenty-two pollen and twenty macrofloral samples were analyzed during Phase II testing. An additional 60 pollen and 71 macrofloral samples were examined for Phase III. Radiocarbon dates suggest eight occupation periods. The earliest occupations of the site from AD 230 to AD 410 and AD 410 to AD 620 appear to have been fairly minor periods of site use. Five features are...

Preliminary examination of a few pollen and phytolith stratigraphic samples from archaeological site 36PE16 in eastern Pennsylvania indicated that both records provided sufficient material for further analysis. Therefore, additional pollen and phytolith samples were examined from strata in three test pits at sites 36PE16 and 36PE61 to describe vegetation change through time. These closely spaced samples track vegetation change during the accumulation of the individual sediment packages. The...

A core was collected from sediments in a seasonally dry glacial kettle lake or pond near Bismark, North Dakota. These sediments are anticipated to represent most of the Holocene and possibly the latest Pleistocene. Pollen samples were collected at close intervals to provide the best possible evaluation of the paleoenvironment. In addition, eight radiocarbon ages were obtained on humates, since there was no charcoal observed in the core, to anchor the pollen record. Dates range from 4900 to...
