This area contains large red spherical sandstone concretions that have eroded out of the softer bedrock, the best example of spheroid rock formations in Alberta. Concretions measure up to 2.5 metres across and are believed to be among largest in the world. There are eroded steep-sided coulees and a small upland of fescue-needle gras. In places, hoodoos (columns of bedrock) have formed. Plants include gumbo primrose, sagebrush, juniper, prickly pear cactus, prairie crocus and broomweed.
