Palisades State Park, South Dakota
Palisades State Park is located where Split Rock Creek flows through a narrow canyon in
Sioux Quartzite bedrock. This canyon was eroded as a meltwater spillway channel during
the Ice Age, when local drainage was blocked and diverted by a glacier. The canyon has
near-vertical walls and isolated rock columns formed in the pink quartzite.
