STS035-76-44 North West Cape, Western Australia, Australia December 1990 This sizable peninsula forms the western border for the Exmouth Gulf of northwest Western Australia. A line of low mountains, known as the Cape Range, extends along the spine or north-south axis of the peninsula. Maximum elevation in these low mountains is 1099 feet (335 meters) above sea level. Some of the lighter colored, angular-looking designs indicate that the vegetative cover, mainly grasslands, has been modified by fires. The clearly defined Ningaloo Reef system borders the west coast of the peninsula.
