2018 Map of Santa Cruz Island B OE S

About this map

Santa Cruz Island rises abruptly from the Pacific Ocean in this topographical study of its southern shoreline. Part of the Channel Islands National Park, the area is defined by sharp elevation changes and deep coastal drainage systems. The landscape is dominated by the Blanca Sierra ridges, which are carved by several prominent seasonal watercourses including Johnston Canyon, Laguna Canyon, and the broad reach of Cañada Posa. This 2018 survey illustrates the complex, unpopulated terrain of the island, where steep slopes and high peaks provide a sanctuary for native flora and fauna far from the California mainland. The lack of infrastructure or modern development highlights the preserved nature of this protected maritime environment.
