Name Origin

The Kingdom Sandstone Member of the Glenwood Formation (Templeton and Willman, 1963, p. 49), the basal member, is named for Kingdom, Lee County.

Type Section

The type section of the Kingdom Member is located 3 miles north of Kingdom, Lee County, in a ravine in Ogle County (NE SE NW 36, 23N-9E) where it is 7.9 feet thick.

Extent and Thickness

The Kingdom Member commonly is 5-20 feet thick but has a maximum thickness of 40 feet.

Stratigraphic Position

In most of the outcrops the Kingdom Member has a sharp contact with the underlying Tonti Sandstone Member of the St. Peter. It thins northward and westward as it grades into the overlying Daysville Member, and farther north the Kingdom Member is equivalent to the lower part of the Nokomis Member.


The Kingdom Member has the poor sorting typical of the Glenwood texture.
