Original description

The Browning Sandstone has been attributed to W.V. Searight (1925–1927), but this was an unpublished manuscript. Wanless (1939, 1956) briefly mentioned the unit. The first proper descriptions, including measured sections, appear in Wanless (1957).


The name refers to a village and township in Schuyler County, northwestern Illinois, where the sandstone fills channels eroded into strata beneath the underclay of the Colchester Coal.
