Cliffs and Lighthouse, Waimanalo, Hawaii, 2001Photograph by Jodi CobbThe red-topped lighthouse on Makapu'u Point stands at the end of a long, fence-lined trail in the southeast corner of Hawaii's Oahu island. Built in 1909, Makapu'u Lighthouse is only 46 feet (14 meters) tall, but its light, concentrated by the largest lens in America, can be seen 28 miles (45 kilometers) out at sea.
