To the east lies Koombolgie sandstone escarpments and spectacular gorges through Nitmiluk National Park. Cliffs are common on coasts, in mountainous areas, escarpments and along rivers. The wilderness is composed of broad plateaus, tall escarpments, and deep canyons. Areas between escarpments are underlain by shales. They are occasionally interrupted by buttes and escarpments. Common caprock locations are escarpments, mesa formations, and salt domes. Views of steep rocky escarpments rising from the plains can be seen. The rim includes steep escarpments and remnants of volcanic flows. The formations are separated by steep escarpments that dramatically interrupt the rolling hills. They form in relatively steep terrain, such as along escarpments and crater walls. The valley is bordered by escarpments to the east and west. The cattle graze on field edges and waysides and on steep escarpments. These escarpments define a caldera caused by the collapse of the summit. Escarpments erode gradually and over geological time. Through the wreaths of fog, forests of trees can be perceived atop these escarpments.
