This bizarre moonscape is the result of two million years of erosion on layers of silt and gravel that were exposed along the active Ostler fault line. The cliffs are on private land; before setting out, pay the vehicle admission fee at Omarama Hot Tubs. To get to the area, head north from town for 3km on SH8, turn left onto Quailburn Rd, and then turn left after 3km onto unsealed Henburn Rd.
