Glacial Drift in Illinois: Thickness and Character
Entry ID: IGDNR_DRIFTTHK


Summary
Abstract: This is an SDE feature dataset showing 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, overlie the bedrock surface in most of Illinois. Glacial ... 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 imagery, air photos, ...
