Badlands are a type of dry terrain which is extremely difficult to move across.[1]
It happens when softer rock is eroded by wind and water, leaving harder rock sticking up. Canyons, ravines, gullies and other such geological forms are common in badlands. They are very difficult to cross by foot, or even on horse, and impossible by car. Dry badlands may have spectacular colour displays that range from dark black/blue coal strata to bright clays and sandstone.
