Name Origin
The Pleasant view Sandstone Member of the Carbondale Formation (Wanless, 1929, p. 90) is named for Pleasantview (now Pleasant View), Schuyler County.
Type Section
The type locality is along Mill Creek (31, 2N-1E) (Wanless, 1956, p. 10; 1957, p. 190).
Extent and Thickness
The sandstone occurs as sheet facies 20 feet or less thick and as channel facies as much as 80 feet thick.
Description
In the channel facies the sandstone cuts through underlying strata down to, and locally through, the Colchester (No. 2) Coal (Ekblaw, 1931; Rusnak, 1957). The sandstone is best developed in western Illinois, but a sandstone commonly present a short distance below the Summum (No. 4) Coal throughout the Illinois Basin is probably equivalent to the Pleasantview. It is generally overlain by several feet of shale, which separates it from the underclay of the Summum Coal.
