==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 />
