In late February 1924, a U.S. Geological Survey team left the Yukon River community of Tanana on dog sleds following a route that would take them through territory largely unknown to outsiders. Their goal was to advance up the Alatna River and establish a camp on the north side of the Arctic Mountains (today's Brooks Range) to wait for spring break-up. Then, they would unpack a crate of cedar canoes they carried on a specially built sled and paddle northward to the Arctic Ocean. Their goal was to explore the 36,000-acre Naval Petroleum Reserve No. 4, an enormous section of Arctic Alaska set aside by President Warren Harding to supply the U.S. Navy with petroleum in times of war.
Government Geologists Cross Central Brooks Range
Although the geologists and topographers of the Geological Survey were accustomed to working in remote and dangerous terrain, the whole enterprise would be a race against time, and Alaskan reporters called this "the most hazardous mission ever undertaken by this branch of the government service." The eight-man team, headed by geologists Philip Smith and John Mertie, included two topographers for mapping, two field assistants, a cook and a dog musher, both recruited from remote Alaskan gold camps. Freight-haulers would also join the first leg of the expedition to deliver several tons of supplies to a point near the Continental Divide. The New York Times called them "all stout lads, hard as nails, with plenty of experience in difficult situations."
Like other Geological Survey expeditions, this one was carefully orchestrated to meet the demands of weather and terrain, but some dangers could not be anticipated. When spring arrived in late May, the men eagerly boarded their canoes only to find vast sheets of overflow ice called aufeis impeding their progress and battering their canoes. And, while struggling to guide the boats through ice-filled channels and over gravel bars, Mertie crushed a bone in his foot, which slowed progress for a week. After reaching the Colville River, the group split into two parties, both of which faced swarms of mosquitoes, back-breaking portages, and the odious task of killing the sled dogs they could no longer feed. Remarkably, the two groups managed to reach Point Barrow within twelve hours of one another and just in time to catch the last ship to Nome before pack ice blocked their passage home.
When news of their success reached the continental United States, Popular Science Monthly declared:
Smith and Mertie were less sanguine about the prospect of finding useful quantities of oil in the Arctic, and warned "no one should risk funds whose loss will seriously embarrass him, because development of oil in this region is distinctly a wildcat undertaking of the most speculative nature." Meanwhile, the sort of foot-slogging geology for which the Geological Survey was famous was becoming obsolete with the arrival of the airplane age in Alaska. Airplanes and later helicopters got the job done in a fraction of the time. Although the efforts of Smith and Mertie and other Survey employees were soon forgotten by the American public, their journey has become part of the history of Gates of the Arctic National Park and Preserve.
