Koyuktolik Bay, also known as Dogfish or Dog Salmon Bay, is about 2 miles (3.2 km) wide and located on the east shore of Cook Inlet at the southwest tip of the Kenai Peninsula, 30 miles (48 km) southwest of Homer and 15 miles (24 km) southwest of Seldovia, Alaska. The name is from an Alutiiq village located here in the 19th century as reported by the U.S. Coast and Geodetic Survey in 1908. Prior to that, the Russians called the bay “Hiko-Bukta”.
The bay has a very large eelgrass bed and salt marsh protected by a gravel spit. The March 27, 1964, Alaska earthquake shook the Kachemak Bay area for about 3 minutes resulting in mainland subsidence of 2-6 feet (0.6-1.8 m). The quake also caused differential compaction of unconsolidated gravel resulting in an additional elevation drop on beaches, river deltas, and spits. For example, the Homer Spit subsided about 6 feet (1.8 m), much of that from gravel compaction.
Many spruce trees located along the shoreline died as a result of saltwater intrusion following the land subsidence resulting in large ghost forests of standing dead trees. Spruce trees have since returned and grown on gravel storm berms above the influence of the tides. Read more here and here. Explore more of Koyuktolik Bay here:
