When the SALT Treaty called for the de-activation of the 18 Titan missile silos that ring Tucson, volunteers at the Pima Air Museum asked if one could be retained for public tours. After much negotiation, including additional talks with SALT officials, the Green Valley complex of the 390th Strategic Missile Wing was opened to the public. It the only Intercontinental Missile (ICBM) silo complex in the world that is open to the public.

After watching a video about the history of the Titan and its deadly nuclear delivery capability, you're taken deep in to the "hardened" command center. Here, essential equipment--indeed the center itself--is mounted on springs to withstand anything but a direct hit. Then you pass through a couple of 6,000-pound blast doors and walk along a space-age corridor to the silo itself. The 110 foot tall missile weighed 170 tons when it was fueled and ready to fly. It's empty and harmless now, but it still looks deadly, crouched on its launch pad.

The Titan Missile Museum is open every day except for Thanksgiving and Christmas from 9am to 5pm. One-hour guided tours of the missile site are offered daily, with the last tour of the day beginning at 4pm. Special behind-the-scene tours are also offered. For more information call (520) 625-7736 or visit the museum's web site at For more information on where other silos were in the country visit the site at

To the box:
The Titan Missile Museum is located in Green Valley, about 20 miles south of Tucson, Arizona. Take I-19 south to exit 69 and head west for about half a mile until you see the signs on the right.

Start at the west post of the entrance gate: Walk 50 paces at 160* and “stop”. Locate a large, very beautiful palo verde tree at 54*. The box is under a concrete rock on the northeast side of this tree.

The standard warning applies when reaching for letterboxes in Arizona:
Rattlesnakes and “mean” things abound,
please take a stick and poke around.
It may save your hand or your life
and help to avoid loads of strife!
