Galbraith Lake is a lake located in the North Slope Borough of Alaska, United States. The surrounding area is uninhabited except for seasonal residents.
The lake is located on the west side of the Dalton Highway between miles 272-75 of the highway. The lake is approximately 3.6 mi (5.8 km) long and was formed by glaciers, and is known to contain lake trout, burbot and grayling fish, with some reports of Arctic char. [1] A campground is also located near the lake. [1] [2]
The lake was named in 1951 after Bart Galbraith, a bush pilot who died in a 1950 plane crash while flying from Barter Island to Barrow. [3] [4] [5]
Galbraith Lake Airport is located in the area, as well as Pump Station 4 of the Trans-Alaska Pipeline System.
A work camp was located at Galbraith Lake during the construction of the pipeline. An oil spill near the camp in 1975 caused some oil to enter the lake and a slick to appear on its surface. [6] [7] [8] [9] Clean up efforts were then conducted. [10]
The infrastructure of the pipeline construction project in the 1970s also permitted the conduct of archeological investigations in the area, which previously had not been explored, funded by the Alyeska Pipeline Service Company. [11] [12] [13]
The Galbraith Lake Bureau of Land Management Campground is 359 miles north of Fairbanks and 140 miles south of Deadhorse at the 275 mile mark. [14]
Galbraith Lake has a cold subarctic climate, bordering on a true tundra climate. Snow has occurred in all three summer months. During the construction of the Alaska Pipeline a weather station was operated at the construction site. [15] Because the weather station was operated for only a decade, the temperature record is irregular, with December the coldest month of the year, and record highs and lows less extreme than those of nearby locations. Likewise, the precipitation record is incomplete, with some months having less than ten years of record.

Alternate prior names for the lake were "Natravak Lake" and "Sagavanirktok Lake." "Natravak" is an Eskimo name for "big lake" and a common name in northern Alaska. [4]
Prudhoe Bay is a census-designated place (CDP) located in North Slope Borough in the U.S. state of Alaska. As of the 2020 census, the population of the CDP was 1,310 people, down from 2,174 residents in the 2010 census, and up from just 5 residents in 2000; however, at any given time, several thousand transient workers support the Prudhoe Bay Oil Field. The airport, lodging and general store are located in Deadhorse, and the rigs and processing facilities are located on scattered gravel pads laid atop the tundra. It is only during winter that the surface is hard enough to support heavy equipment, and new construction happens at that time.

The Trans-Alaska Pipeline System (TAPS) is an oil transportation system spanning Alaska, including the trans-Alaska crude-oil pipeline, 12 pump stations, several hundred miles of feeder pipelines, and the Valdez Marine Terminal. TAPS is one of the world's largest pipeline systems. The core pipeline itself, which is commonly called the Alaska pipeline, trans-Alaska pipeline, or Alyeska pipeline,, is an 800-mile (1,287 km) long, 48-inch (1.22 m) diameter pipeline that conveys oil from Prudhoe Bay, on Alaska's North Slope, south to Valdez, on the shores of Prince William Sound in southcentral Alaska. The crude oil pipeline is privately owned by the Alyeska Pipeline Service Company.
The James W. Dalton Highway, usually referred to as the Dalton Highway, is a 414-mile (666 km) road in Alaska. It begins at the Elliott Highway, north of Fairbanks, and ends at Deadhorse near the Arctic Ocean and the Prudhoe Bay Oil Fields. Once called the North Slope Haul Road, it was built as a supply road to support the Trans-Alaska Pipeline System in 1974. It is named after James Dalton, a lifelong Alaskan and an engineer who supervised construction of the Distant Early Warning Line in Alaska and, as an expert in Arctic engineering, served as a consultant in early oil exploration in northern Alaska. It is also the subject of the second episode of America's Toughest Jobs and the first episode of the BBC's World's Most Dangerous Roads.
Gates of the Arctic National Park and Preserve is an American national park that protects portions of the Brooks Range in northern Alaska. The park is the northernmost national park in the United States, situated entirely north of the Arctic Circle. The area of the park and preserve is the second largest in the U.S. at 8,472,506 acres ; the National Park portion is the second largest in the U.S., after the National Park portion of Wrangell–St. Elias National Park and Preserve.
The Canol Road was part of the Canol Project and was built to construct a pipeline from Norman Wells, Northwest Territories, to Whitehorse, Yukon, during World War II. The pipeline no longer exists, but the 449 kilometres (279 mi) long Yukon portion of the road is maintained by the Yukon Government during summer months. The portion of the road that still exists in the NWT is called the Canol Heritage Trail. Both road and trail are incorporated into the Trans-Canada Trail.
Deadhorse is an unincorporated community located within the CDP of Prudhoe Bay in North Slope Borough, Alaska, United States, along the North Slope near the Arctic Ocean. The town consists mainly of facilities for the workers and companies that operate at the nearby Prudhoe Bay Oil Field. Deadhorse is accessible via the Dalton Highway from Fairbanks, 495 mi (797 km) south, or Deadhorse Airport. Limited accommodation is also available for tourists.
The Canol Project was constructed during World War II to ensure a supply of oil for the defense of Alaska and the North American west coast. The project was completed in two years at great cost and was abandoned less than a year later.
Umiat (OO-mee-yat) is an unincorporated community in North Slope Borough, Alaska, United States. It is located on the Colville River, 140 miles southwest of Deadhorse in the Arctic Circle. The town is not accessible by road or rail, only by air or river.
Prudhoe Bay Oil Field is a large oil field on Alaska's North Slope. It is the largest oil field in North America, covering 213,543 acres (86,418 ha) and originally contained approximately 25 billion barrels (4.0×109 m3) of oil. The amount of recoverable oil in the field is more than double that of the next largest field in the United States by acreage (the East Texas Oil Field), while the largest by reserves is the Permian Basin (North America). The field was operated by BP; partners were ExxonMobil and ConocoPhillips until August 2019; when BP sold all its Alaska assets to Hilcorp.
The Prudhoe Bay oil spill was an oil spill that was discovered on March 2, 2006, at a pipeline owned by BP Exploration, Alaska (BPXA) in western Prudhoe Bay, Alaska. Initial estimates of the five-day leak said that up to 267,000 US gallons (6,400 bbl) were spilled over 1.9 acres (7,700 m2), making it the largest oil spill on Alaska's north slope to date. Alaska's unified command ratified the volume of crude oil spilled as 212,252 US gallons (5,053.6 bbl) in March 2008. The spill originated from a 0.25-inch (0.64 cm) hole in a 34-inch (86 cm) diameter pipeline. The pipeline was decommissioned and later replaced with a 20-inch (51 cm) diameter pipeline with its own pipeline inspection gauge (pig) launch and recovery sites for easier inspection.
Prospect Creek is a very small settlement approximately 180 miles (290 km) north of present-day Fairbanks and 25 miles (40 km) southeast of present-day Bettles, Alaska. Years ago it was home to numerous mining expeditions and the camp for the building of the Trans-Alaska Pipeline System (TAPS). Today, it is the location of Pump Station 5 of the TAPS. Prospect Creek is also home to the United States record for lowest temperature. On January 23, 1971 the record low temperature of −79.8 °F (−62.1 °C) was recorded. Wildlife can be found there even with its extreme changes in temperature; local fauna include anything from black and brown bears to bald eagles. The elevation of Prospect Creek is 643 feet (196 m) above sea level. Nearby Moore Creek is widely known for its gold and quartz mining and sits alongside Prospect Creek in Alaska’s Innoko Mining District. The Innoko Mining District is famous for its findings of large quartz.
Thompson Pass is a 2,600 foot-high gap in the Chugach Mountains northeast of Valdez, Alaska. It is the snowiest place in Alaska, recording 500 inches (1,300 cm) of snow per year on average. In the winter of 1952–1953, 974.1 inches (2,474 cm) of snow fell—the most ever recorded in one season at one location in Alaska. It is not the most snow ever recorded in one season at one location anywhere in the fifty states as that record belongs to Mount Baker Ski Resort at 1140 inches in 1998-99. The pass also holds the Alaska record for the most snow in a single day: 62 inches (160 cm) fell on December 29, 1955.
The construction of the Trans-Alaska Pipeline System included over 800 miles (1,300 km) of oil pipeline, 12 pump stations, and a new tanker port. Built largely on permafrost during 1975–77 between Prudhoe Bay and Valdez, Alaska, the $8 billion effort required tens of thousands of people, often working in extreme temperatures and conditions, the invention of specialized construction techniques, and the construction of a new road, the Dalton Highway.
Galbraith Lake Airport is a state-owned, public-use airport located at Galbraith Lake in the North Slope Borough of the U.S. state of Alaska. The Arctic National Wildlife Refuge has an office at the airport. The lake and airport are located west of the Dalton Highway and north of the Trans-Alaska Pipeline System's Pump Station 4. According to the FAA's National Plan of Integrated Airport Systems for 2009–2013, it was classified as a general aviation airport.
Walter Bruce "Walt" Parker was an American civil servant, policy adviser, transportation adviser, academic and local politician. Parker's career focused on the development of natural resources, transportation and infrastructure in Alaska from the 1940s to the 2000s. In 1989, Alaska Governor Steve Cowper appointed Parker as the chairman of the Alaska Oil Spill Commission, which investigated the Exxon Valdez oil spill. He is credited with making important contributions to the fields of transportation, telecommunications, education, land use and urban planning within the state of Alaska. Parker was inducted into the Alaska Conservation Hall of Fame by the Alaska Conservation Foundation in 2002 for his contributions to state conservation.
Max Clifton Brewer (1924–2012) was an Arctic scientist, geophysicist, geological engineer, environmentalist, educator, and philosopher, and is best known for his expertise in the scientific field of permafrost. He was the longest-serving director (1956-1971) of the Naval Arctic Research Laboratory (NARL) in Utqiaġvik, Alaska where he established and managed the NARL ice stations in the Arctic Ocean. From 1971-1974 he served in the gubernatorial cabinet of William A. Egan as the first commissioner of the Alaska Department of Environmental Conservation.
Toolik Lake is an Arctic lake located within the North Slope Borough, Alaska. It is in a remote wilderness area managed by the Bureau of Land Management accessed by the Dalton Highway. It is 130 mi (210 km) south of Prudhoe Bay in the northern foothills of the Brooks Range. The name is derived from the Iñupiat word tutlik, meaning yellow-billed loon.
