Winniwissa Falls
Small waterfall at Pipestone National Monument in Pipestone, Minnesota.
These rocks are about 1.6 billion years old. Several layers of Sioux quartzite, which is harder than ordinary steel, overlay the soft, red pipestone (aka catlinite) layer. This catlinite isn't found anywhere else in the world.
Native American tribes from near and far have been coming to quarry this pipestone for thousands of years. The site is very sacred to them.
