2015 Map of Santa Rosa Island North

About this map

Santa Rosa Island rises from the Pacific Ocean in this 2015 survey, depicting the northern coastline and surrounding marine boundaries within the Channel Islands National Park. The topographic detail highlights a dramatic landscape defined by steep drainage systems and coastal erosional features, including the deep cut of Cow Canyon and the neighboring drainage of Canada Lobos. As a federally protected area off the coast of Santa Barbara County, the map illustrates the rugged transition from the island's interior peaks down to the sea, where bathymetric contour intervals trace the submerged slopes. The boundary for California and Santa Barbara County extends far into the open water, signifying the maritime reach of state and local jurisdiction over these offshore waters.
