==Name Origin==<br />
The Gimlet Sandstone Member of the Modesto Formation (Wanless, 1931a, p. 182, 183, 190, 192) is named for Gimlet Creek in Marshall County.<br />
==Type Section==<br />
The type section consists of exposures along Gimlet Creek (N 1/2 SE 16, 12N-9E) (Wanless, 1956, p. 11; 1957, p. 116).<br />
==Extent and Thickness==<br />
The Gimlet Sandstone is locally developed as a fine- to medium-grained channel sandstone 50-60 feet thick, which cuts down from 50 feet above the Danville Coal to within a few feet of the Brereton Limestone. In other places the sandstone is only a few feet thick or is absent. The Gimlet Sandstone has been recognized principally in northern and western Illinois. <br />
