Description:

Abstract:

This metadata file describes a GeoTIFF image of the surficial geological units of the 7.5-minute Alton quadrangle in Illinois. The image is limited to the quadrangle portion of the map sheet.

The data were published in 1999 on an ISGS Illinois Geologic Quadrangle entitled Surficial Geology Map, Alton Quadrangle (Illinois Portion) Madison County, Illinois by David Grimley. These data do not include all the information on the published map. Refer to the published map for a complete explanation of the Quaternary geology of the Alton quadrangle.

The nominal scale is 1:24,000.

Purpose:

This image is intended to provide a regional overview of the extent of Quaternary geologic materials in the Alton quadrangle. The image is not appropriate as a geodetic or engineering base, nor does it replace the need for detailed site-specific studies.
