Historical:Granger Sandstone Member
M. E. Hopkins and J. A. Simon
The Granger Sandstone Member of the Spoon Formation (Kosanke et al., 1960, p. 32) is named for Grangertown, Kentucky.
Grangertown is near Indian Hill, Union County, Kentucky, the type locality (Glenn, 1912, p. 24-26).
It was originally called the Curlew Sandstone (Owen, 1856, No. 1 vertical section).
Extent and Thickness
About 40 feet of Granger Sandstone is well exposed in the Creal Springs Quarry in Williamson County (25, 10S-3E). The sandstone is probably present in much of the deeper part of the Illinois Basin.
The Granger Sandstone is widespread in southern Illinois, occurring in channel and nonchannel facies and varying considerably in thickness and bedding characteristics.
