Maps, Charts, and Geographic Information Systems Data
The sanctuary consists of five separate areas abutting six of the main islands in the state of Hawai‘i. The five areas of the sanctuary cover relatively shallow offshore areas built up from the sea floor by the development of the Hawaiian Island chain. Though underwater, the sanctuary actually lies near the summit of a massive undersea volcanic mountain range.
