Geoarchaeological investigations in western Middle Park provide important information for understanding the soil-stratigraphic context of Paleoindian components, as well as the latest Quaternary environmental change and landscape evolution in a South

Middle Park, a high-altitude basin in the Southern Rocky Mountains of north-central Colorado, contains at least 59 known Paleoindian localities. At Barger Gulch Locality B, an extensive Folsom assemblage (˜10,500 14C yr B.P.) occurs within a buried

Mima-like mounds in the Laramie Basin, Wyoming, are circular in plan view, lens or funnel-shaped in cross-section, and frequently have relief of 15 to 65 cm. They consist of churned materials derived from adjacent/subjacent soils and sediments. Stron

Mima-like mounds in the Laramie Basin occur where: (1) impervious bedrock (shale) is at a shallow depth (∼ 2–5 m); (2) bedrock is overlain by a thin veneer (∼ 1–4 m) of alluvial gravels; and (3) a strong argillic/calcic or petrocalcic soil ca

From phytolith and soil data, earlier researchers concluded that Cinnabar Park, a dry grassland surrounded by coniferous forest on a high interfluve (2928 m) in the Medicine Bow Mountains, Wyoming, has migrated downwind (east) by snowdrift action. Ho

Relatively complete stratigraphic records of the Bonneville cycle and of at least one and probably two earlier lacustrine are exposed along the Bear River below Cutler Dam in northern Utah between altitudes of 1290 and 1365 m. In most exposures the u

The White River Plateau erosion surface (Miocene-Pliocene) at an elevation of approximately 2850 m (9500 ft) is dominated by weakly developed Holocene soils which commonly possess simple A-C horizonation. However, Pre-Wisconsin soils occur on the sur
