Abstract

Jewel Cave National Monument (hence referred to as JECA) occupies 516 ha on the southwestern edge of the Limestone Plateau area of the Black Hills (Custer Co., South Dakota). Underlain by the resistant Pahasapa limestone (Mississippian), it is characterized by steep topography and deep canyons, with elevations ranging from roughly 1550 to 1750 m above sea level. Ponderosa pine forest dominates the landscape. Much of the forest was logged at least once prior to being incorporated into the Monument during a US Forest Service-National Park Service land swap in the early 1960's. Roughly one quarter section (the "old area") was part of the original Monument and has not been logged.
