Summary
Abstract: This map is a digital Arc/Info line and polygon coverage of drift thickness in
Illinois. Data are originally from ISGS Circular 490 by Piskin and Bergstrom
(1975), Plate 1. Contours (lines) are coded with thickness, and polygons (areas
between contours) are coded with range of thickness. Nominal scale is
1:500,000.

Unconsolidated deposits, mainly glacial drift, ... View entire text

Purpose: These data may be used to determine approximate depth to bedrock in regional
areas of the state (eg. townships). The data are not of sufficient detail for
use in determining drift thickness for specific locations. The data can be used
for physical or environmental models of the state's unconsolidated geologic
materials, eg. coupled with geophysical information, satellite ... View entire text
