2018 Map of Santa Rosa Island West

About this map

Channel Islands National Park encompasses the northwest terrain of this island landscape, where deep drainage systems meet the Pacific Ocean. This 2018 survey illustrates the physical geography of a protected coastal environment defined by narrow canyons that cut through high elevations toward the sea. The hydrological network is dominated by major outlets such as Arlington Canyon, along with the neighboring Cañada Tecolote and Cañada Soledad. These seasonal watercourses carve the upland slopes, creating a distinct topographical profile of ridges and draws that has remained largely free of modern development. The map serves as a primary record of the island's shoreline and interior canyons within Santa Barbara County, providing an exact account of the natural features and park boundaries during the early twenty-first century.
