A 3.2 mile trail to Crow Peak Summit, with a 0.5 mile spur trail to Beaver Ridge.
Crow Peak is a dominant landmark because of its geological makeup. Billions of years ago, this area was covered by an ocean. Layers of sediment were deposited on the ocean floor, eventually hardening to form limestone and other sedimentary rock layers.
Underground molten rock called magma pushed the sedimentary layers upward forming hills. During the uplifting, crevasses within the limestone hills filled with magma. These flows of magma, called intrusions, cooled to form igneous rock.
The limestone and other sedimentary rock erodes at a faster rate than the harder igneous rock. As the oceans receded, the overlying sedimentary rock eroded, exposing the igneous intrusions. Crow Peak and other peaks you can see from Crow Peak summit, such as Bear Butte, Spearfish Mountain, and Terry Peak, were formed in this manner. Erosion of the igneous rock and the sedimentary rock surrounding these peaks continues to shape the landscape of the Northern Black Hills.
Hear the winds through the pines while getting excellent views of neighboring granite spires and mountains from a scenic overlook point access by a short cement sidewalk from the nearby 5 site picnic area, parking lot and accessible bathroom.
The Spring Creek Picnic Area has eight picnic sites. Restroom facilities are available. The picnic area is located adjacent to Spring Creek, in an open forest/woodland of ponderosa pine, oak, willow and cottonwood.
Deerfield Reservoir is located 20 miles west of Hill City, SD. The Bureau of Reclamation manages the dam and water. Castle Creek flows into and out of the reservoir and provides additional fishing opportunities. Ice fishing, snowmobiling and ice skating are popular winter sports here. The complex has three campgrounds, two boat launches, two picnic areas and the Deerfield Lake Loop Trail (Trail #40L). Travel on the reservoir is limited to five miles per hour and there is a no-wake restriction which provides for peaceful fishing and boating experiences.
Reservoir water levels and boat ramp data can be found on the Bureau of Reclamation website for Pactola and Deerfield Reservoirs: http://www.usbr.gov/gp/boat/
