Crow Peak Trailhead (Trail #64) the Forest Service's write-up

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.

About this trail's facts

The lines are the US Forest Service's National Forest System trails layer (public domain), read 2026-10-16 and simplified for the map; the length is the line's, end to end, and the class, surface, grade and tread width are the forest's own entries where it publishes them - a forest that publishes the centreline alone has none. The trailheads and the points along the way are the Service's recreation points, and the write-ups its own recarea text, unedited. Heights come from USGS 3DEP through Terrain Tiles on AWS (Mapzen/Tilezen), read along each line and rounded; a short trail on steep ground can be off by a few tens of feet. Closures change: check the forest's own site before you go.
