Stop #3: Minnelusa Formation
in
Wind Cave
Geologic age: Pennsylvanian & Permian

Drive 3.9 miles north on route 385. Park at the Wind Cave Canyon trailhead. A short hike on the trail (1 mile round trip) is required. Outcrops of this formation are on the left side of the canyon.

The Minnelusa Formation consists of interbedded limestones, sandstones and shales. It is yellow to red, with the shales being a grayish cream. Interbedded means that the limestones, sandstones, and shales alternate with distinct horizontal layers.

Can you see distinct layers? How are the layers different from those seen in the Minnekahta Limestone?

Is there something we missed for this itinerary?
