The U.S.'s newest National Park the Channel Islands lie between California's mainland coast and the deep ocean's Continental Shelf. Here the sea floor is comprised of canyons, underwater plateaus, escarpments, sea mounts and deep basins. Santa Cruz Basin is deeper than the Grand Canyon. This topography - shallow and deep, smooth and rugged, sunlit and sometimes dark with fog - creates habitats for a diversity of species.
In this view from the Island Packer's tour boat to the Islands, is Santa Cruz Island, with a large sedimentary mesa slanting into the ocean. An anchored sail boat provides scale. And shrouded in the typical coastal fog.
