The Bisti Badlands feature a variety of unique rock formations, such as hoodoos and cracked eggs, created by millions of years of erosion on layered sandstone, shale, mudstone, and coal. The landscape was once a swamp in an inland sea during the late Cretaceous period, and these formations are remnants of that ancient environment. Erosion from wind and water carves away the softer materials, leaving behind bizarre and often otherworldly stone shapes.
