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, overlie the bedrock surface in most of Illinois. Glacial drift ranges from less than a few feet to approximately 600 feet in thickness. The thickest drift occurs in major preglacial valleys cut into the bedrock and filled with glacial sediments. Regionally thick drift occurs in the N.E. portions of the state. The thinnest drift, less than 25 feet thick and intersected by numerous bedrock outcrops, occurs widely in southern and western portions of the State. Drift, as shown on this map, may include any of the following: unconsolidated deposits glacial drift Wisconsinan deposits Illinoian deposits till glaciofluvial deposits glaciolacustrine deposit wind-blown deposits (loess) 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, hydrologic data, or other data in a Geographic Information System at a statewide scale of 1:500,000. Supplemental_Information: Updates to the data: Edition 1.0 of this data set was replaced by this edition (2.0) in June, 1998. These data were reviewed as described in the logical consistency report and process steps for May, 1998. Contour values, which were not included in edition 1.0, are included in this version.
