Description: <DIV STYLE="text-align:Left;"><DIV><DIV>This data set was updated in 2014 by the Wyoming State Geological Survey. Polygons were merged, description information was completed, and geologic units were converted to representations to retain unit colors and patterns.The geologic map was digitized by Green, G.N., and Drouillard, P.H., 1994, from original scribe sheets used to prepare the published 1:500,000-scale Geologic Map of Wyoming (Love and Christiansen, 1985). Stable base contact prints of the scribe sheets were scanned on a Tektronix 4991 digital scanner. The scanner automatically converts the scanned image to an ASCII vector format. These vectors were transferred to a VAX minicomputer, where they were loaded into Arc/Info. The dataset includes both linear and polygon features, with attributes derived from the original 1985 map.

Query indicates uncertainty of position of top of unit within the Pleistocene.2. Age of upper parts of uppermost Miocene units is problematic. These parts have historically been assigned to the Pliocene. Successive reductions in radiometric age of the top of the Miocene in Europe to 7 Ma (Lambert, 1971) and to 5 Ma (Berggren, 1972) place a Pliocene age in question, although the top beds of the formations have not been dated.3.
