This dive site offers a unique historical journey into a flooded Titan I Missile Silo, a relic from the Cold War era. Located on private property in Washington State, access is strictly managed through UnderSea Adventures. Divers explore the salvaged remains of the control room, missile silos, and equipment terminals within this overhead environment. Navigation involves following guide lines or experienced instructors through the dark and confined spaces of the submerged facility, providing a glimpse into a significant piece of military history.
As an artificial, freshwater, enclosed environment, the Titan I Missile Silo does not host typical marine animals or extensive plant life. Divers might encounter some freshwater invertebrates like insects, larvae, or very small fish species that have adapted to this unique ecosystem, though sightings are generally rare and not the primary focus of the dive. There is no coral or significant aquatic vegetation.
The best time to visit this dive site is dependent on booking availability with UnderSea Adventures, as it's a controlled access location. Divers should possess advanced certification and overhead environment training due to the unique challenges of the silo. Tips for divers include proper buoyancy control to avoid silting, carrying multiple light sources, and being prepared for cold, dark water conditions. This site is not suitable for snorkeling or freediving due to the overhead environment and specialized nature of the dive.
