2018 Map of San Miguel Island West

About this map

Channel Islands National Park encompasses the western portion of San Miguel Island in this 2018 survey. The landscape is defined by the elevation of Green Mtn, which rises above the surrounding sea cliffs and coastal bluffs. As the westernmost point of the northern Channel Islands, this area is almost entirely surrounded by the Pacific Ocean, with the map illustrating the complex shoreline and offshore rocks that characterize this protected maritime environment. The terrain exhibits significant topographic variation, with contour lines detailing the ridgelines and drainage patterns of the island's interior away from the coastal margins.
