This dive site, Summit Lake, offers a unique high-altitude freshwater diving experience situated on the south slope of the Alaska Range. Accessible via the Richardson Highway, it's located above the tree line at an elevation of 3300 feet (approximately 1000 meters). Divers must account for altitude diving procedures and be prepared for cold water. The underwater environment likely consists of rocky slopes and possibly silty bottoms, with depths ranging from an average of 5 meters to a maximum of 11 meters. There is no specific historical information regarding the lake as a dive site beyond its natural setting.
The lake is not stocked but is rumored to contain some fish, though specific species are not identified. Due to its alpine environment, marine plant life would be sparse and limited to hardy aquatic vegetation in shallower areas. Divers should not expect an abundance of marine life, making the appeal more about the unique environment than biodiversity.
The best time to visit Summit Lake for diving would be during the Alaskan summer months, when surface conditions are most tolerable, though the water will remain extremely cold, necessitating drysuits and robust thermal protection. Divers should possess experience in cold-water and altitude diving. A significant consideration for any visit is the presence of bears in the surrounding area, requiring strict adherence to bear safety protocols. This site is ideal for adventurers seeking a challenging and unusual diving experience rather than a typical vibrant marine encounter.
