Whoopie Cat Mountain
Location

Ecological and Physical Description
Whoopie Cat Mountain RNA contains relatively undisturbed examples of glade and dry upland forest natural community types. The area was identified as significant by the Illinois Natural Areas Inventory (1978) because of its very high quality limestone glade and the presence of two uncommon plant species: the orange coneflower (Rudbeckia fulgida) and the crested coralroot orchid (Hexalectris spicata). The latter species is a Shawnee National Forest Listed species and is also listed as an Illinois Endangered Species. The area also contains another Illinois Threatened Species, the climbing milkweed (Matelea obliqua).
Annual precipitation averages approximately 46 inches (116 cm) and ranges from 32 to 70 inches (81-177 cm). Precipitation is fairly evenly distributed throughout the year, although prolonged dry spells during the growing season are not uncommon. Average annual snowfall ranges between 10 to 15 inches (25.4 - 38.1 cm).
The climatological data are from the collection station at New Burnside, IL, which has records dating from 1931. The station is located 27 miles (44 km) north west of the RNA.
Rocks of the glade are of the Golconda Group of the Chester Series (Mississippian). Two formations of the Golconda Group are represented on the RNA; the uppermost is the dark, medium-grained argillaceous Beech Creek Formation, underlain by Fraileys Shale which consists of thin beds of calcareous limestone. Much of the RNA has exposed bedrock, and where there is soil present, it is thin and results from weathering of the bedrock.
The RNA is located just north of Whoopie Cat Lake and just south of Tecumseh Lake (both man-made lakes), and runoff from the RNA drains into both lakes. A small spring and seep are found near the top of the glade on the northwest-facing slope, which yields enough water during the wet seasons to supply a small surface flow. The RNA is located within the Big Creek watershed.
