Sitting pretty on the west side of Nicasio Reservoir in the rolling terrain of west Marin County this shapely lone mountain easily catches the eye and dominates the scene. Also known as Elephant Mountain it is one of countless "Black Mountains" throughout the state and country.

Either some dude named Black and his descendants went on a nation wide rampage naming mountains in his namesake or people should develope a little imagination. If anything it looks more like an elephant than it is black.

Characterized by steep slopes divided into ribs by evenly spaced gullies this symetrically balanced hill draws the lense of photographers to capture it's serene beauty especially from the shores of the reservoir.

Unfortunately it sits on private property. On the other hand there is a free annual hike open to the public organized from Point Reyes Station.
There are many higher points in the county but Black Mountain's isolated position affords one of the finest views in Marin.

See the Red Tape section for the information needed to participate in the hike.
