The name "Black Hills" comes from the Lakota words Paha Sapa, which mean "hills that are black". Seen from a distance, these pine-covered hills, rising several thousand feet above the surrounding prairie, appear black. The Black Hills are in western South Dakota and northeastern Wyoming, covering an area 125 miles long and 65 wide. They encompass rugged rock formations, canyons and gulches, open grassland parks, tumbling streams, deep blue lakes, and unique caves.<br><br>Amid the splendid scenery are 11 reservoirs, 30 campgrounds, 26 picnic areas, 2 scenic byways, 1,300 miles of streams, 13,605 acres of wilderness, over 450 miles of trails, and much more.
