About this map

Gibraltar Reservoir serves as the focal point for this mid-1960s study of the San Rafael Mountains and its surrounding wilderness. The infrastructure of the Los Padres National Forest is well-documented, featuring essential outposts such as Happy Hollow Guard Station and Madulce Guard Sta, alongside the remote Ogilvy Ranch. The map highlights a landscape managed for both water resources and wildlife protection, specifically noting the Sisquoc Condor Sanctuary near the Sisquoc River.

Transport through the steep terrain relies on a network of primitive routes like the Santa Ynez Camino Cielo and Buckhorn Road, while the mineral history of the region is anchored by the Gibraltar Mine located just south of the Gibraltar Dam. Notable high points including Big Pine Mountain and Madulce Peak dominate the topography, providing a detailed record of this protected California backcountry before modern expansion.
