About this map

Big Basin Redwoods State Park and Portola State Park dominate this landscape within the Santa Cruz Mountains, illustrating the conservation and recreational development of the mid-20th century. The presence of Park Headquarters (Big Basin PO) serves as a focal point for the region's managed wilderness, while scattered settlements like Riverside Grove, Redwood Grove, and Wildwood along the San Lorenzo River indicate small clusters of community growth amidst the timber. A notable institutional presence is found at Camp Ben Lomond (California Youth Authority) to the south.

The map reveals an intricate network of watercourses, including Pescadero Creek and Boulder Creek, which historically supported local industry as evidenced by a Sawmill and Quarry. Significant elevation markers such as Butano Ridge and Ben Lomond Mtn define the drainage patterns. Roadways like the China Grade and various jeep trails provide insight into early access routes through these often dense forest areas, while Locatelli Ranch represents the agricultural heritage of the Santa Cruz and San Mateo county borderlands.
