Mount Bielawski, also spelled Mount Bielewski, is a 3,234-foot summit in California’s Santa Cruz Mountains near the San Francisco Bay Area and the highest point in Santa Cruz County. Lying just southwest of the Santa Cruz–Santa Clara county line and Highway 35, it is notable more for elevation than scenery, as its heavily wooded summit offers no broad views. In some winters it receives snow, reflecting the cooler, wetter conditions of the higher ridges. The mountain was named for Casimir Bielawski, chief draughtsman in the Surveyor General’s office, and was also known as Mount McPherson after landowner Duncan McPherson.
