Item Number: OFS17-04

This preliminary map is an interim geologic map product prepared to document progress accomplished during the second year of a multiyear project to map the bedrock geology of Morgan County, Indiana. The Paragon quadrangle is located in the southwestern portion of the county where the oldest rock units subcrop in paleovalleys filled with glacial outwash deposits. All the outcropping and subcropping rocks in the map area are assigned to the Lower and Middle Mississippian formations of the Borden and Sanders Groups---in ascending order, these map units include the informal upper division of the Spickert Knob Formation, Edwardsville Formation, Ramp Creek Formation, and Harrodsburg Limestone.
