==Stratigraphic relationships==<br />
The Bernadotte Sandstone Member forms the top of the Abbott Formation in western Illinois.<br />
<br />
==Extent and thickness==<br />
The Bernadotte Sandstone is fairly extensive in western Illinois and attains thicknesses of 18 feet, though it commonly averages about 5 feet.<br />
<br />
==Lithology==<br />
It is very fine grained, only slightly micaceous, and the upper part is commonly cemented with silica. The Bernadotte differs from most Pennsylvanian sandstones in generally having a flat base and an uneven top, on the thicker parts of which overlying stratigraphic units tend to wedge out (Wanless, 1957).<br />
