Kahoolawe, a single shield volcano, consists of a nearly filled caldera and a rift zone that trends to the southwest. Kahoolawe is about 12 miles (20 km) across and the smallest of the major Hawaiian Islands. This photo is looking to the east. Photo by Jack Lockwood, U.S. Geological Survey, March 31, 1984.
The Hawaiian island of Kahoolawe is located between the islands of Maui and Lanai and it is approximately 45 square miles in size. It has been known as the "forgotten isle", "desolate isle", and the "target isle". Kahoolawe has been used at different times as a penal colony, a ranch, a forest reserve, and a military training and testing ground.
There are no hotels, restaurants or any type of tourism infrastructure on Kahoolawe. There is still a danger of visitors encountering unexploded ordnance on the island so access is limited to those who receive permission from the Kahoolawe Island Reserve Commission for purposes related to restoration, education, and Hawaiian culture.
