Historical:Athensville Coal Member
M. E. Hopkins and J. A. Simon
The Athensville Coal Member of the Modesto Formation (Kosanke et al., 1960, p. 37) is named for Athensville, Greene County.
The type section consists of exposures near the town (SE NW SW 16, 12N-9W, Macoupin County).
It previously was called Upper Scottville (Kosanke, 1950, p. 85).
It may correlate with the Lake Creek Coal of southern Illinois.
Extent and Thickness
It occurs in southwestern Illinois.
The Athensville Coal generally lies less than 10 feet below the Scottville Limestone.
