Description

A snowy Spearfish Canyon. Black Hills of South Dakota. Spearfish Canyon is a deep but narrow gorge carved by Spearfish Creek just south of Spearfish, South Dakota in the U.S. It is located on the northern edge of Black Hills National Forest. Many tourists drive through the canyon, drawn to the region due to its wide range of plant and wildlife, geology, rock formations, and waterfalls. Spearfish Creek holds populations of rainbow and brown trout and is dammed in several spots, affording fishing opportunities. Stocking of trout in Spearfish Creek was discontinued in the 1970s and all trout in the creek today are wild. In addition, remnants of Spearfish Canyon's active mining history are still easily found in some locations. It is often studied by geologists due to the extreme old age of the Precambrian rocks exposed by the Creek bed. The Canyon's high walls are of three dominant rock types. Deadwood shale at the bottom can be identified by its brown color, is multi-layered in appearance and ranges from 10 to 400 feet thick. Englewood limestone in the middle is pink to red colored and is 30 to 60 feet thick. Paha sapa limestone, the top layer, is the thickest (300 to 600 feet) and is buff colored and weathered gray in appearance. Caves and fossils are frequently found in Paha sapa limestone. dakota, south dakota, spearfish canyon, snow, spearfish, canyon, wall, walls, spruce, tree #201101232231
