Whittier Cessna

The Whittier Cessna is an intriguing dive site in Prince William Sound near Whittier, Alaska, where a small aircraft resting on the seafloor has become both a local diving attraction and an artificial reef that has attracted the cold-water marine community of this remote Alaskan fjord system. This beginner-rated site offers divers an unusual wreck experience in some of Alaska's most strikingly beautiful coastal scenery, where glaciers calve into the sea and the towering Chugach Mountains rise directly from the water's edge. Prince William Sound is among the most dramatic coastal environments in North America, with deep fjords, tidewater glaciers, and the extraordinary productivity of subarctic Pacific waters creating a marine ecosystem of extraordinary richness. The sound gained international attention as the site of the 1989 Exxon Valdez oil spill, and the subsequent decades of monitoring and recovery have provided remarkable insights into the resilience and vulnerability of these northern marine communities. Today the sound supports thriving populations of marine mammals, birds, and fish that have largely recovered from the spill. The Cessna aircraft resting on the seafloor has been claimed by the cold-water marine community in the way that artificial reefs are everywhere. The aircraft's structure provides the hard substrate that sessile organisms require, and the cold Alaskan water's extraordinary biological productivity has covered the airframe in the dense growth of anemones, hydroids, and other encrusting organisms that characterize Pacific Northwest artificial reefs. The aircraft's silhouette remains recognizable, creating the combination of historical interest and biological richness that makes wreck diving so compelling. The marine life around the Whittier Cessna reflects the extraordinary productivity of Prince William Sound. Rockfish shelter beneath the aircraft's wings and in the cockpit area, their territorial behavior creating resident populations that divers encounter on every visit. Sea stars in multiple species navigate the surrounding substrate, while nudibranchs and other invertebrates that thrive in cold, nutrient-rich Pacific Northwest water populate the aircraft's colonized surfaces. Diving at Whittier requires cold-water preparation and the logistics of reaching this remote Alaskan port, but the combination of spectacular scenery, the unique aircraft wreck, and the rich cold-water marine community makes it a memorable experience for divers seeking Alaska's extraordinary underwater world.
