The team got out for an early evening hike recently to Battery Townsley, one of several pre WWII military installations in the Marin headlands. This is one of the Bays classic day hikes, both easily accessible and packed with awe inspiring views of the Headlands, San Francisco and even the Farallon's on a particularly clear day. The dry, bushy headlands also play host to a stealthy if abundant wildlife population including bobcats, wild turkeys, and several birds of prey. We packed our TL Pack with lunch, water and camera equipment and headed off for the day.
Battery Townsley's construction kicked off in 1928, took twelve years to complete, and once held gigantic guns capable of shooting 2,100 pound, armor-piercing projectiles 25 miles out to sea. Most of the Battery and bunkers reinforced concrete structure is buried in the hill tops of the headlands with various doors and tunnels leading into hallways and eventually into the two enormous turret areas where you can look out on the Pacific from the gigantic concrete deck.
Townsley is only a short drive North on highway one from SF, but the site was originally considered a high security operation. Folks living in SF during the time of construction and active use had little knowledge of the enormous structure, its capabilities, or its location. The site is long since decommissioned and now falls under the care of the National Park Service.
