Mount Umunhum Environmental Restoration and Public Access Project (Phase 1 Demolition)
Document Type
FIN - Final Document

Document Description
Note: FYI Final The project includes phased public access to the summit of Mount Umunhum, as well as roadway and access improvements, ecological restoration, and development of public use facilities and a range of possible amenities such as trails, observation and reflection areas, interpretive displays, picnic tables, shade structures, restrooms, camp sites, hang glider facilities, and a visitor center. The project also includes longer term plans to allow public access to the summit of Mount Thayer from the Lexington Basin. No access to Mount Thayer from Mount Umunhum is proposed as part of this project. Implementation of the proposed project includes demolition of most, possibly all, of the existing structures associated with the former Almaden Air Force Station located at the site. The project includes three alternatives for the treatment of the existing radar tower.
