The valley, which is only about across and long, is full of thousands of mushroom-shaped pinnacles. These pinnacles are each a few meters high. Because of their height and shape, people referred to them as goblins. They are made of large orange-brown boulders of hard rock on top of weaker sandy layers. The sandy layers have eroded more quickly causing their shape. The "Goblins" are well hidden from the nearby road. The land to the east is flat and empty. It is near a long narrow ridge with eroded layers of grey and red-brown rocks. The far side of this empty land gives the best views of the landscape. The Goblins look as if they join with the cliffs. This gives giving the look of a strange skeletal structure with skull-like rocks and bony ridges.
