What is the name of this defining landmark?

Arguably the most famous landmark in the Islands, this volcanic cone stands 762 feet above Waikiki on the island of Oahu. Its Hawaiian name is Leahi, from lae (promontory) and ahi (tuna), because the ridgeline resembles the shape of a tuna's dorsal fin.

Its English name comes from the 19th-century British sailors who mistook its beta quartz crystals for this precious metal.

Fort Ruger, the first U.S. military installation in Hawaii, once occupied some of the interior and exterior areas of the crater. A National Guard facility and the Hawaii State Civil Defense are there today.
