Book Description

Excerpt from Geology and Mineral Resources of the Herscher Quadrangle Very little of the topography, except the bluffs of Kankakee River, is determined by the bedrock of the area. Nearly all the relief features are con structional by glacial agencies, but in the path Of the Kankakee glacial torrent they have been modified by running water and subsequently by wind. The greater portion of the quadrangle is occupied by a shallow basin between two glacial moraines (broad ridges of glacial drift), one on the southern edge and one in the northeastern corner. Nowhere is the topography rough, and the total difference in altitude between the highest and lowest points in the quadrangle is only about 210 feet. Pilot Knob, in sec. 2, T. 29 N., R. 10 E., is the highest point and stands Slightly more than 750 feet above sea level.
