Kenai Fjords National Park

Kenai Fjords National Park is a national park on the Kenai Peninsula in south-central Alaska, near the town of Seward. It protects the Harding Icefield, one of the largest icefields in the United States, and the fjords, glaciers and marine wildlife of the Gulf of Alaska coast. It was proclaimed a national monument in 1978 and became a national park in 1980 [1].

Overview

Kenai Fjords National Park was established as a national monument on December 1, 1978, by President Jimmy Carter, and was redesignated a national park on December 2, 1980 under the Alaska National Interest Lands Conservation Act. The legislative boundary encloses 669,650 acres, of which 603,130 acres are managed by the National Park Service and about 569,000 acres are eligible wilderness [1].

The Harding Icefield

The Harding Icefield is the park’s largest feature and covers about half of it. The ice measures about 700 square miles in total, roughly 50 miles long and 20 miles wide, and its highest surface reaches about 5,200 feet. It is thousands of feet thick, but it does not completely cover the mountains beneath, and mountaintops that poke through the ice are called nunataks, meaning lonely peaks [1][2]. The icefield formed more than 23,000 years ago during the Pleistocene as a remnant of a much larger ice sheet that covered Southcentral Alaska [2].

Glaciers

At least 38 glaciers flow from the icefield according to park fact sheets, and more than a dozen end within the park, including Exit, Bear, Aialik, Holgate and Northwestern glaciers [1]. Different glaciers end on land, in lakes or in tidewater. Glaciers in the park lost 11.2 percent of their ice between 1950 and 2005 [1]. Exit Glacier ends on land and can be reached by a short trail from the ranger station [2].

Hiking

The Exit Glacier valley has trails of 0.5 to 1.5 miles one way. The Harding Icefield Trail climbs about 4.1 miles one way with roughly 3,500 feet of elevation gain, reaching the edge of the icefield. The Exit Glacier area receives about 200 inches of snow a year [1][2].

Fjords and Coast

The park has over 545 miles of coastline for kayaking and camping without maintained trails, and public use cabins are available at places such as Aialik and Holgate [1]. Boat tours leaving from Seward allow visitors to see tidewater glaciers and wildlife from the water.

Wildlife

The park supports about 30 species of land mammals, 10 species of marine mammals, 200 bird species and 40 fish species. Threatened or endangered species include humpback, sei and gray whales and the Steller sea lion, while species of concern include the Kittlitz’s murrelet, peregrine falcon and harbor seal [1].

Climate

The climate is temperate maritime, moderated by the Alaska Coastal Current. Summer temperatures range from the mid-40s to the low 70s °F, while winters range from the low 30s down to -20 °F [1]. On the icefield itself, a weather station at 4,200 feet recorded temperatures from -21 °F to 68 °F and a peak gust of 117 miles per hour over its first three years [2].

Human History

The Sugpiaq (Alutiiq or Pacific Yupik) have lived in the area for thousands of years, using ocean and land resources, and their descendants live in communities such as Nanwalek and Port Graham [1].

Visitors

The park recorded 356,601 recreation visits in 2019 [1]. Seward serves as the main gateway, and most visitors come in the summer for glacier hikes and boat tours.

Formation of the Fjords

The fjords of the park are glacial valleys that were carved by ice and then flooded by the sea as the glaciers retreated. Steep walls rise directly from the water, and glaciers still end in tidewater in places such as Aialik Bay. The Harding Icefield, as a remnant of a much larger ice sheet, continues to shape the coastline [1][2].

Icefield Research

The icefield and its outlet glaciers are a focus of monitoring. The park fact sheet reports that glaciers lost 11.2 percent of their ice between 1950 and 2005, and weather stations on the icefield record conditions that influence regional climate [1][2]. Because the icefield keeps nearby land and water cold, it acts as a driver of local weather as well as a reservoir of ice [2].

Marine Life

The cold, productive waters of the Gulf of Alaska support humpback whales, sea lions, harbor seals and many seabirds. Several of these species are protected under federal law, and the park’s fact sheet lists humpback, sei and gray whales and the Steller sea lion as threatened or endangered [1]. Tour boats leaving Seward bring visitors close to these animals and to the tidewater glaciers.

Park Operations

The 2019 fact sheet reports 30 permanent staff, 46 seasonal staff and 14 volunteers, supported by base appropriations of about million, which shows how modest the park’s operating scale is relative to its visitor numbers and area [1]. Most visitor services are concentrated at Exit Glacier and in Seward.

Seward and the Surrounding Area

The town of Seward, on Resurrection Bay, serves as the park’s mailing address and main gateway [1]. From there the Exit Glacier area is reached by road, while the fjords are reached by boat. Together with the Kenai National Wildlife Refuge, which contains Truuli Peak at 6,612 feet, the park forms part of a large protected landscape on the Kenai Peninsula [1].

Planning a Visit

Summer is the main season, when temperatures are mild and boat tours run, while winter brings heavy snow and limited access. Hikers should prepare for rapidly changing mountain weather on the Harding Icefield Trail, and kayakers should be prepared for cold water and tides in the fjords [1][2].
