Department of Transportation “ledges” or
rock subdivisions (for example, “1011”).
These ledges have good physical testing
values reported by the Indiana Department
of Transportation (A is good, G is bad). The
thickness of the bench-ledge combinations are
noted. Many minerals, including world-class
pink, curved dolomite crystals can be found in
the quarry. There are also both an upper level
air-filled cave in the upper Ste. Genevieve and
a mud-filled lower level cave likely in the upper
124
St. Louis which have been uncovered during
mining operations (Figure 26). Both features
will be mined eventually. The Indiana State
Museum assisted by the Indiana Geological
Survey has been conducting a salvage effort
of the speleothems for display in the museum
in Indianapolis. Figure 26 is a photo of the
north highwall of the quarry. Figure 27 is a
panoramic vista looking south from the top
of Pennington Chapel Ridge toward Corydon
and the Crawford Upland.
