Kenai Peninsula

The Kenai Peninsula extends about 150 miles (240 km) southwest from the Chugach Mountains south of Anchorage, between Cook Inlet and Prince William Sound. It is known for the Kenai River’s king salmon, Kenai Fjords National Park, the Kenai National Wildlife Refuge and towns such as Seward, Soldotna, Kenai and Homer. Most of it lies within the Kenai Peninsula Borough [1].

Geography

The peninsula extends about 150 miles southwest from the Chugach Mountains. Cook Inlet separates it from the mainland to the west, and Prince William Sound lies to the east. Glacier-covered Kenai Mountains run along the southeast spine facing the Gulf of Alaska, with much of the range in Kenai Fjords National Park, while the northwest Cook Inlet shoreline is flatter and dotted with small lakes [1].

Rivers, Lakes and Ice

Skilak Lake and Tustumena Lake lie in the interior. The Kenai River is famous for king salmon fishing, and the Kasilof and Anchor Rivers also cross the peninsula. The Sargent and Harding Icefields feed numerous glaciers, including Tustumena, Exit and McCarty Glaciers. Kachemak Bay reaches the southwest end, where much of the land is in Kachemak Bay State Park [1].

Name and Early Peoples

Kenai comes from the Kenaitze, and the Dena’ina called the peninsula Yaghenen, meaning the good land. Athabascan and Alutiiq peoples lived on the peninsula for thousands of years before Russian colonization [1]. See the entries on the Dena’ina and Alutiiq peoples.

Towns and Transportation

Seward, Soldotna, Kenai, Sterling, Cooper Landing and Homer are among the most populous towns in Southcentral Alaska. Homer marks the end of North America’s paved highway system, and Seward is the southern terminus of the Alaska Railroad. The Seward Highway links Seward to Anchorage, and the Sterling Highway connects population centers to it. Kenai and Homer have commercial airports, the Alaska Marine Highway serves Homer and Seldovia, and Seward is a major cruise ship port [1].

Resources and Economy

The peninsula has natural gas, petroleum and coal deposits plus commercial and personal-use fisheries. Tourism is a major industry, alongside outfitting and guiding for hunters and anglers [1].

Wildlife Refuge

The Kenai National Wildlife Refuge covers nearly two million acres of the peninsula [1]. See the entries on the Wildlife of Alaska, the Alaska Railroad and Southcentral Alaska.
