About this map

The ridge of the Santa Cruz Mountains serves as the boundary between Santa Cruz and Santa Clara counties, characterized by sharp elevation changes and deep creek drainages. High-altitude points such as Mount Bielawski and The Peak overlook a landscape of gulches and ridges, including Diamond Ridge and Oak Ridge. The area reflects a history of both education and recreation, as seen in the presence of Alma College, Montezuma School, and youth retreats like Stuart Camp and Redwood Camp.

Infrastructure is anchored by Skyline Boulevard, which traces the crest of the range. To the east, the settlement of Monte Sereno shows early urban expansion, while the western slopes descent toward Boulder Creek. Water management is prominent through features like Lexington Res, Howell Reservoirs, and Lompico Res, which capture the runoff from several local streams including Bear Creek and Saratoga Creek.
