“ An eastern coast range borders the Gulf of California, and in places attains elevations considerably exceeding 6000 feet. The western coast range, bordering the Pacific, is less elevated and seldom exceeds 3500 feet in altitude. At the extreme south the peninsula terminates in an immense mountain mass, rising in San Lázaro to 8000 feet altitude. The coasts are considerably indented, but there are not many really good harbors. ”
