Koyuktolik Bay, Cook Inlet

Koyuktolik Bay, also known as Dogfish or Dog Salmon Bay, is located on the east shore of Cook Inlet at southwest tip of the Kenai Peninsula. There was an Alutiiq village here in the 19th century. The bay has a very large eel grass bed and saltmarsh protected by a gravel spit. The March 27, 1964 Alaska earthquake shook the Kachemak Bay area for about 3 minutes resulting in a 2- to 6-feet (0.6-1.8 m) subsidence of the mainland. The quake also caused differential compaction of unconsolidated gravel resulting in an additional elevation drop. 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. Trees have since grown on gravel storm berms above the influence of the tides.
