Minnelusa Formation is an exposed band of sedimentary rock in Wind Cave Canyon and the third stop on the park’s self-guided geology drive. It’s a focused detour for anyone who likes reading a landscape through its rocks; if geology isn’t your thing, a mile-long round trip for one outcrop is an easy skip.

On the canyon’s left side, the formation appears in alternating horizontal beds of limestone, sandstone and shale. The colors run from yellow to red, while the shale is grayish cream. Compare these layers with the Minnekahta Limestone at Stop 2 to see how two neighboring formations differ.

A window into the Black HillsThe Minnelusa beds date to the Pennsylvanian and Permian periods.

The Minnelusa beds date to the Pennsylvanian and Permian periods. Across this part of the Black Hills, shallow seas periodically left sediments over much older rock. The hills rose into a dome about 70 million years ago, and erosion cut down through the layers to expose the rocks you see here.

The self-guided geology drive covers about 20 miles and seven stops, with a 60-to-90-minute estimate for the outing. For this stop, park at Wind Cave Canyon trailhead, 3.9 miles north on US 385, then walk about one mile round trip to the outcrop. The canyon route is a gravel service road with uneven ground and occasional steep grades; visitor vehicles do not continue past the trailhead. Pick up the printed stop guide and geologic timeline at the visitor center, and fuel up before the drive—there’s no gas sold in the park.
