A map showing the proposed route of the transpacific cable from Hawaii to the Philippines and including the recently completed San Francisco to Honolulu route. In describing the seafloor from San Francisco to Honolulu, Earle Ashley Walcott wrote in the February 1903 edition of "Sunset" magazine, "The ocean bed slopes rapidly down from the Golden Gate until a depth is reached of a little over two miles. Then the slope becomes more gentle, and in eight hundred miles comes to a depth of 19,116 feet. There is then a sudden rise of four thousand feet--about the height of Mount Hamilton--which reduces the depth to 15,114 feet. Once over this mountain the road to Honolulu runs for several hundred miles along a broad valley some 18,000 feet--or about three and one-half miles--below the ocean's surface. Then it passes over a mountain rim, rising 11,000 feet to within 7200 feet of the surface, dips down again into a narrow valley 17,256 feet beneath the waves, and then climbs the mountain range that shoots its highest peaks above the surface to make the Hawaiian Islands."
