Sierra Morena (brown range) is the name of a spur of the Coast Range commencing about ten miles south of San Francisco and running through San Francisco County into Santa Clara County. This mountain range, which contains some very charming scenery, may have been so named on account of its color, or it may be the namesake of the Sierra Morena of Spain. The name is sometimes spelled Moreno, and one of the possibilities is that it was named for the pioneer Moreno family.
