1993 Map of Santa Rosa Island

About this map

Santa Rosa Island sits at the center of this topographic-bathymetric study, which extends from the northern reaches of Channel Islands National Park into the depths of the Pacific Ocean. This map illustrates the dramatic underwater topography of the Santa Barbara coast, where the shelf drops precipitously along the Patton Escarpment and Patton Ridge. Near the island's shores, the survey identifies maritime landmarks such as Bee Rock and the protected waters of Bechers Bay. The landscape is defined by its transition from the terrestrial peaks of the Channel Islands to subterranean features like Trask Knoll and the San Miguel Gap. This 1993 edition incorporates 1943 topographic data with 1981 planimetry and bathymetric surveys from the National Ocean Service, providing a dual view of the region's physical geography above and below the waterline.
