One of the most famous and spectacular Tertiary deposits in North America is the White River Badlands. The colorfully banded, fossiliferous, highly dissected landscapes are exposed across much of southwestern South Dakota; a specific landmark is difficult to designate. Most visitors to the Badlands traverse the area in the Badlands National Park between the towns of Interior and Wall in Pennington and Jackson Counties (Fig. 1). Most geological features may be viewed along South Dakota 240, the Badlands Loop; therefore this area has been designated a landmark. Geology is well-exposed along the route at such localities (Fig. 1) as the Pinnacles, Yellow Mounds, Rainbow Overlook, Banded Buttes Overlook, and Cedar Pass. Due to space limitations herein, frequent references are made to the road log, photographs, and bibliographic references of the area by Martin (1985).
