Sac Tunnel/Sac Hill Tunnel/Subway Tunnel/Subway
Located on the eastern flank of Sacramento Hill and part of the Sacramento Mine, They started driving the tunnel in January 1910. The design was to have the tunnel (adit) intercept the Sacramento Shaft 75ft. below the collar. It was intended to use this tunnel to explore part of Sacramento Hill in preparation for developing the Sacramento Pit. A substantial concrete portal was built at the entrance. The site was destroyed by the Lavender pit during the 1950s. In January of 2011 Heavy equipment working around the site uncovered the concrete cornice of the adit. Today, the cornice can be seen lying upside down at the base of Sacramento Hill at the edge of the pit. This adit should not be confused with another Sacramento adit that was located on the Southwestern side of the mountain and was used to transported men and materials to the shaft for hoisting.
