Big Manitou Falls in Wisconsin’s Pattison State Park contains a unique river gorge carved out of both sandstone and basalt and includes the 165' high roaring, cascading falls of the Black River. In the few thousand years since the last glacier retreated, the river slowly eroded through the layers of soft sandstone and clay and gradually formed the steep sided gorge. This small slice shows only a portion of the highest waterfall in Wisconsin, but I wanted to draw attention to the beauty of the rushing water and the wet black rocks that form the gorge.
