| This view from the Pinnacles Overlook area shows  a few scattered cedars and a remnant of grass-covered pediment surface, called  a “table.”  Grassy tables stand out of  patches of green amongst the badlands that surround the headwaters region of  East Fork of Sage Creek.  Sage Creek is a  tributary of the Cheyenne River, which flows north and eastward into the  Missouri River in central South Dakota. |
