The digital map publication, compiled from previously published and unpublished data and new mapping by the author, represents the general distribution of surficial and bedrock geology in Pipe Spring National Monument and vicinity, including the following 1:24,000-scale U.S. Geological Survey (USGS) quadrangles: Moccasin, Kaibab, Pipe Valley, and Pipe Spring. Together with the accompanying geologic description pamphlet, it presents current knowledge of the geologic structure and stratigraphy of the area covered. The database identifies map units that are classified by age and lithology following the stratigraphic nomenclature of the USGS. The scale of the source maps limits the spatial resolution (scale) of the database to 1:24,000 or smaller. Note: The extent of this database conforms to the boundaries of the four quadrangles listed above; however, the topographic base maps produced by the USGS for the Moccasin and Kaibab quadrangles extend slightly to the north of the 37-degree latitude line that should define the northern limit of these 7.5- minute quadrangles. Thus, if this database is overlain with a digital file of quadrangle boundaries there is a mismatch.
