The geology coverage was developed from the 1972 USGS Geologic Map of Yellowstone National Park. It contains polygons of bedrock formations, dikes, and faults. Errors in the 1972 map were corrected and an area outside the Park boundary on the west and south was added. Attributes attached to each polygon include a formation code, formation name, formation age, and a generalized unit name. Line attributes include water, contacts, and faults. Updated information includes a break down of Tertiary, and Quaternary volcanic rock units.
The conversion of bedrock geology information of the park into a digital format enables easy overlay with other layers for analysis and development of other themes. The release of the basic data now will give those who need it geologic data for Yellowstone National Park in a timely manner. The data have been reprojected to be in UTM zone 12 meters, and have been adjusted to the North American Datum of 1983. These data are not intended to be used at a scale greater than 1:100,000.

The assignment of attributes to the polygon information is complete and accurate for the data at this scale. Line attribution is not complete.
Map elements were checked visually for overshoots, undershoots, duplicate features, polygon closure, and other errors by the authors. In addition, automated (ARC/INFO) routines were used to check the database for polygon label errors, line attribution errors, sliver polygons, dangling arcs, intersection errors, and projection information.
All geologic features shown on the 1972 geologic map are contained in the current database with the exception of the dikes. The original map was modified by R.L. Christiansen. His later geologic mapping is contained within this coverage.
Geologic features were located with a precision that is associated with professional field methods and geologic data compilation methods. Since National Map Accuracy Standards apply to the base map with which these data are registered, then the maximum location accuracy of the geologic data at this scale is approximately 65 meters.

For geologic information for Yellowstone National Park prior to 1972, the following are contributions listed on the map: Quaternary volcanic rocks by R.L. Christiansen, and H.R. Blank, 1966-70. Absaroka volcanic rocks by H.W. Smedes and H.J. Proska. Pre-volcanic rock in the northern part of the Park by E.T. Ruppel, 1965-68; I.J. Witkind, G.D. Fraser, H.A. Waldrop, and H.J. Hyden; W.B. Hall; W.G. Pierce. Pre-volcanic rocks by J.D. Love, 1945-49, 1964-67, and W.R. Keefer, 1966-67. Surficial deposits mainly after G.M. Richmond, K.L. Pierce, and H.A.
