2021 Map of Santa Cruz Island B OE S

About this map

Channel Islands National Park encompasses the coastal topography shown in this 2021 survey of the southern shore of Santa Cruz Island. The map details a landscape defined by dramatic elevation changes and sharp drainages, where the Blanca Sierra ridges descend toward the Pacific Ocean. The coastline is marked by distinct features such as Morse Point and the sheltered waters of Posa Anchorage. Inland, the terrain is carved by significant geographic features like Cañada Posa, Johnston Canyon, and Laguna Canyon, which channel toward the sea. Just offshore, the isolated landmass of Gull Island stands as a prominent maritime landmark. This modern topographic record captures the preserved natural state of the island, emphasizing the complex relationship between high sierra peaks and the rugged coastal shelf without the presence of human settlements or road networks.
