Glacier Bay National Park and Preserve is a United States national park and preserve in the Alaska panhandle west of Juneau. President Calvin Coolidge proclaimed the area around Glacier Bay a national monument under the Antiquities Act on February 25, 1925.[3] Subsequent to an expansion of the monument by President Jimmy Carter in 1978, the Alaska National Interest Lands Conservation Act (ANILCA) enlarged the national monument by 523,000 acres (2116.5 km²) on December 2, 1980 and in the process created Glacier Bay National Park and Preserve,[4] with 57,000 additional acres (230.7 km²) of public land designated as national preserve to the immediate northwest of the park in order to protect a portion of the Alsek River and related fish and wildlife habitats while allowing sport hunting.

Glacier Bay became part of a binational UNESCO World Heritage Site in 1979, was inscribed as a Biosphere Reserve in 1986 and in 1994 undertook an obligation to work with Hoonah and Tlingit Native American organizations in the management of the protected area.[5] In total the park and preserve cover 5,130 square miles (13,287 km²). Most of Glacier Bay is designated wilderness area which covers 4,164 square miles (10,784 km²).[6]

Geography[edit]

Map of Glacier Bay National Park and Preserve

Glacier Bay National Park and Preserve occupies the northernmost section of the southeastern Alaska coastline, between the Gulf of Alaska and Canada. The Canadian border approaches to within 15 miles (24 km) of the ocean in the St. Elias Mountains at Mount Fairweather, the park's tallest peak at 15,300 feet (4,700 m), transitioning to the Fairweather Range from there southwards. The Brady Icefield caps the Fairweather Range on a peninsula extending from the ocean to Glacier Bay, which extends from Icy Strait to the Canadian border at Grand Pacific Glacier, cutting off the western part of the park. To the east of Glacier Bay the Takishna Mountains and the Chilkat Range form a peninsula bounded by the Lynn Canal on the east, with the park's eastern boundary with Tongass National Forest running along the ridgeline. The park's northwestern boundary, which also abuts Tongass National Forest, runs in the valley of the Alsek River to Dry Bay. The preserve lands comprise a small area at Dry Bay — the majority of Glacier Bay lands are national park lands. The park boundary excludes Gustavus at the mouth of Glacier Bay. The lands adjoining the park to the north in Canada are included in Tatshenshini-Alsek Provincial Park.[7]

No roads lead to the park and it is most easily reached by air travel. During some summers there are ferries to the small community of Gustavus or directly to the marina at Bartlett Cove.[8] Despite the lack of roads there are over 400,000 visitors each year most of whom arrive via cruise ship. The number of ships that may arrive each day is limited by regulation.[8] Other travelers come on white-water rafting trips, putting in on the Tatshenshini River at Dalton Post in the Yukon Territory and taking out at the Dry Bay Ranger Station in the Glacier Bay National Preserve.[9] Trips generally take six days and pass through Kluane National Park and Reserve in the Yukon and Tatshenshini-Alsek Provincial Park in British Columbia.[9]

Environment[edit]

Glacier Bay National Park preserves nearly 600,000 acres (2428.1 km²) of federally protected marine ecosystems in Alaska (including submerged lands) against which other less-protected marine ecosystems can be compared.[5] Within the park and preserve there are two Tlingit ancestral homelands that are of cultural and spiritual significance to living communities today.[5] The Alsek River serves as a route of discovery and migration from the coastal mountain range in the park to the Pacific Ocean in the preserve.[5] Within the preserve, in contrast to the park, the Alsek River provides a setting for subsistence uses, commercial fishing, and hunting as provided for in the Alaska National Interest Lands Conservation Act (ANILCA) while simultaneously protecting the glacial ecosytem.[5]

There are fifteen tidewater glaciers in the park.[10] Glaciers descending from high snow capped mountains into the bay create spectacular displays of ice and iceberg formation. In the last century the most dramatic was probably the Muir Glacier. The calving face was nearly 2 miles (3.2 km) wide and about 265 feet (81 m) high. Glacier Bay National Park and Preserve includes nine tidewater glaciers. Four of these glaciers actively calve icebergs into the bay. In the 1990s the Muir Glacier receded to the point that it was no longer a tidewater glacier. Most visitors today travel to the Margerie and Lamplugh Glaciers. The advance and recession of the park's glaciers has been extensively documented since La Perouse visited the bay in 1786. In general the glaciers of the Fairweather Range are advancing and the Chilkat Range glaciers are receding.[10]

The region is being lifted by tectonic activity, with frequent earthquakes. Earthquake-induced landslides have been significant forces for change, inducing tsunamis that are believed to have reached 1,600 feet (490 m) in height.[10]

Regions of the park closest to the Gulf of Alaska have a relatively mild climate with significant rainfall and comparatively low snowfall. Lower Glacier Bay is a transitional zone, and upper Glacier Bay is cold and snowy. Access to the land can be difficult, since the glacial fjords have steep walls that rise directly from the water. Where there are shoreline flats they can be densely vegetated with alder and devils club, making hiking difficult. Ecosystems in the park are wet tundra, Alpine tundra, coastal forest, and glaciers and icefields.[10]

Wildlife in the area includes both grizzly and black bears, moose, sitka black-tailed deer, mountain goats, dall sheep, wolves, Canada lynx, sea otters, harbor seals, Steller sea lions, Pacific white-sided dolphins, orcas, minke whales, humpback whale, bald eagles, gulls, waterfowl, and salmon.

Glacial retreat[edit]

Joseph Whidbey, master of the Discovery during the 1791-95 Vancouver expedition, found Icy Strait, at the south end of Glacier Bay, choked with ice in 1794. Glacier Bay itself was almost entirely covered by one large tidewater glacier.[11] In 1879 naturalist John Muir found that the ice had retreated almost all the way up the bay, a distance of around 48 miles (77 km).[12] By 1916 the Grand Pacific Glacier was at the head of Tarr Inlet about 65 miles (105 km) from Glacier Bay's mouth. This is the fastest documented glacier retreat.[8] Not all of park's glaciers are in retreat.[8] Scientists working in the park and preserve hope to learn how glacial activity relates to climate change.

Activities[edit]

About 80% of visitors to Glacier Bay arrive on cruise ships. The National Park Service operates cooperative programs where rangers provide interpretive services aboard the ships and on the smaller boats that offer excursion trips to more distant park features.[13] In-park accommodations are available at the Glacier Park Lodge.[14] The park and preserve hosts many outdoor activities such as hiking, camping, mountaineering, kayaking, rafting, fishing, and bird-watching. Unlike many other national parks in Alaska, subsistence hunting is not allowed in the park, only in the preserve.[15]

Sport hunting and trapping are also allowed in the preserve. To hunt and trap, you must have all required licenses and permits and follow all other state regulations. The National Park Service and the State of Alaska cooperatively manage the wildlife resources of the Preserve. Campers and hunters should be aware that brown bears are common in the Preserve and be prepared to avoid conflicts with them. Typically hunted species in the Preserve include American black bear, mountain goat, wolf, wolverine, snowshoe hare, ptarmigan, waterfowl and a number of furbearers. There is one big game hunting guide authorized through concession contracts to operate within Glacier Bay National Preserve. Three lodges and one outfitter can provide transportation and services for fishing and hunting small game and waterfowl.[16]

Sport fishing is another activity popular in the park. Halibut are frequently esteemed by deep-sea fishers and in rivers and lakes Dolly Varden and rainbow trout provide sport. An Alaskan sportfishing license is required for all nonresidents 16 and older, and residents 16-59, to fish in Alaska's fresh and salt waters.[17]

History[edit]

Prehistory and exploration[edit]

The earliest traces of human occupation at Glacier Bay date to about 10,000 years before the present, with archaeological sites just outside the park dating to that time. Evidence of human activity is scarce, because so much of the area is or was glaciated for much of the period and because advancing glaciers may have scoured all traces of historical occupation from their valleys. Ongoing uplift of the land may reveal new sites that had been submerged by rising sea levels. Most archaeological evidence is from the last 200 years. The Haida, Eyak and Tlingit all could have occupied the coast until historical times, when the Tlingit came to dominate the area.[10]

Jean-François de Galaup, comte de Lapérouse was the first European to explore the Alaskan coast in the region of Glacier Bay in 1786, arriving in Luituya Bay and making contact with the Tlingit. A Russian ship visited in 1788, claiming the region for Russia. The region was later visited by George Vancouver in Discovery in 1794, during his during the Vancouver Expedition.[10] The explorers are believed to have seen the Glacier Bay ice at its peak, which coincided with their visits.[18] Russians were chiefly concerned with the area until the 1880s, when Americans were drawn to Alaska and the Klondike by the Klondike Gold Rush of the 1890s. A cannery was established in Dundas Bay in 1890, and the first tourist ships arrived in 1893.[10]

John Muir visited Glacier Bay in 1879, just prior to the 1880 establishment of Yosemite National Park, Muir's first great cause. Muir came to Alaska to learn about glaciers as a means of understanding the formation of the glaciated landscape of the Yosemite Valley. Muir sent dispatches back to San Francisco to be published in the San Francisco Bulletin in both 1879 and 1880, eventually collecting these stories, accounts of his third and fourth trips in 1890 and 1899, and later lectures and articles into the 1915 book Travels in Alaska, promoting Glacier Bay and the Inside Passage. Muir's writings led to the naming of Muir Glacier, then nearly 300 feet (91 m) tall at tidewater and the most active glacier in the bay, after Muir.[19]

The Pacific Coast Steamship Company ran tours up the Inside Passage from Tacoma and Portland during the 1890s, highlighting Muir Glacier and Glacier Bay. The accessibility of Glacier Bay brought naturalists and geologists to study, survey and name the glaciers. The Harriman Alaska Expedition of 1899 was organized by railroad executive Edward Harriman who recruited Muir, George Bird Grinnell, photographer Edward S. Curtis and several others to study the Alaska coast on a specially-outfitted ship, spending five days at Glacier Bay. The expedition noted significant glacial retreat. A few months later the magnitude 8.0 earthquake that shook Yakutat Bay on September 10, 1899 caused Muir Glacier to collapse into the bay, filling it and making it less attractive to tourists, and after 1900 Taku Glacier became a popular destination.[19] In 1900 a salmon cannery was established at Dundas Bay, operating until 1931.[20]

Muir's writings attracted the attention of William Skinner Cooper, an ecologist at the University of Minnesota, who saw the bay's retreating glaciers as an opportunity to study plant succession on the recently exposed land. He visited Glacier Bay in 1916, surveying the glaciers and inlets and establishing nine test plots to be monitored in future visits. Cooper returned to Glacier Bay in 1922, wrote a paper for the Ecological Society of America in which he proposed that Glacier Bay be protected as a national monument.[19][21]

The Ecological Society established a committee to promote the designation of Glacier Bay as a national monument at the urging of Cooper, forwarding copies of their resolutions to President Calvin Coolidge, the National Park Service, the Smithsonian and the governor of Alaska. The idea was opposed by the U.S. Geological Survey, which reported that the area had potential for mineral extraction. The Interior Department decided to send an agent to survey the area, assigning George Alexander Parks of the General Land Office, and a future governor of Alaska, to examine the area and to canvass local residents. Parks' 1924 report recommended a very limited boundary designed to include glaciers and little else. In response Cooper and the Ecological Society undertook a letter-writing campaign that supported the Park Service and caused Coolidge to add some portions of mature forest to the Parks boundaries. Coolidge's proclamation under the Antiquities Act of Glacier Bay National Monument came on February 26, 1925.[22]

National Monument[edit]

Alaska game managers came under heavy criticism in the 1920s for a perceived lack of interest in protecting Alaskan brown bears. The state approached the Park Service with a proposal to expand the boundaries of the Glacier Bay monument using land from Tongass National Forest as a bear sanctuary. Park Service studies were favorable, and the Forest Service came to view an expansion of Glacier Bay as preferable to the designation of Admiralty Island as a national park, which was first proposed in the 1930s. By the late 1930s Ernest Gruening, the director of the Department of Territories and Island Possessions and future governor of Alaska, suggested that the entire region be protected in a single unit extending up the Saint Elias Range to the Wrangell Range. The substance of Gruening's idea would not be realized until 1978, when Wrangell-St. Elias National Monument would be proclaimed. In the meantime, the Wrangell-St. Elias proposal was set aside in favor of expansions to the east for bear habitat and to the west to protect the Gulf of Alaska coastline. President Franklin D. Roosevelt used the Antiquities Act to expand the monument on April 18, 1939, creating the largest unit in the national park system at the time.[23]

During World War II the U.S. Army appropriated an area around Excursion Inlet to be used as a logistics base for transferring materiel from barges transiting the Inside Passage to seagoing vessels, logging the area for pilings to be used in piers. The base was never used. At the same time the Army built an airfield at Gustavus, which offered flat terrain and good weather. The airfield was completed too late to participate in the Aleutian Campaign. However, it was one of four Alaskan airfields suitable for use by B-29s, with 5,000-foot (1,500 m) and 7,500-foot (2,300 m) runways and modern navigation equipment.[24] In 1955 the area around Gustavus was removed from the monument and returned to the public domain, together with 10,184 acres (4,121 ha) at Excursion Inlet.[25]

No Park Service personnel were assigned to the monument until 1949, when a seasonal ranger was stationed at Bartlett Cove. The monument was administered locally from 1953 onwards. Starting in 1957 the facilities at Bartlett Cove were expanded as part of the Park Service's Mission 66 program with employee housing and maintenance facilities. An administrative site was also developed outside the monument boundaries at the Forest Service ranger station at Indian Point on Auke Bay, closer to Juneau.[25] The Glacier Bay Lodge was built to accommodate guests in 1966. Beginning in 1969 cruise ships became regular visitors to the monument.[14]

In 1958 survey crews found a rich deposit of copper and nickel ore under the Brady Icefield. Investigators looked at a nunatak outcrop in the icefield and found highly mineralized rock. Newmont Exploration Ltd. proposed the construction of a 3-mile (4.8 km) adit to an underground mine under the icefield, with a mill at the portal opening and a road to piers at Dixon Bay. This proposal took advantage of 1936 legislation that permitted mineral exploitation in the monument, which had been confined to small prospectors until this time. In response to this and other proposals, Montana senator Lee Metcalf proposed the Mining in the Parks Act to resolve and eventually prohibit mining at Glacier Bay and five other parks and monuments. However, the final bill contained a number of significant exemptions, and the Newmont claim has never been resolved, although no mining activity has been proposed since the 1970s.[26][27]

National Park and Preserve[edit]

As a result of the 1971 Alaska Native Claims Settlement Act (ANCSA), 80,000,000 acres (32,000,000 ha) of Alaskan public lands were eligible for inclusion in the national park system. Studies for expansion of Glacier Bay focused on the area around the Alsek River. Facing an approaching deadline imposed by ANCSA to resolve land allotment and seeing delays in the proposed Alaska National Interest Lands Conservation Act (ANILCA) in Congress that was intended to make a final settlement, President Jimmy Carter used his authority under the Antiquities Act to proclaim fifteen National Park Service units in Alaska on December 1, 1978. The proclamation also expanded Glacier Bay National Monument to include the Alsek lands. The final ANILCA legislation, signed into law by Carter on December 2, 1980, established Glacier Bay National Park and Preserve from the national monument. The Alsek addition comprised the bulk of the preserve lands. The chief distinction between park and preserve lands is that sport hunting by non-residents is permitted in accordance with Alaskan game regulations in the preserve, but prohibited in the park.[28]

World Heritage Site[edit]

The Kluane-Wrangell-St. Elias-Glacier Bay-Tatshenshini-Alsek transborder park system comprising Kluane, Wrangell-St Elias, Glacier Bay and Tatshenshini-Alsek parks, was declared a UNESCO World Heritage Site in 1979 for the spectacular glacier and icefield landscapes as well as for the importance of grizzly bears, caribou and Dall sheep habitat. The Glacier Bay National Park was added in 1992 to the Heritage Site.[29]
