Jack London spent a single winter in the Canadian North during the Klondike Gold Rush of 1897-1898. When he returned, he claimed to have come upon a mythic wolf which inspired the character of Buck in The Call of the Wild. Whether or not London was speaking of a true encounter, his experiences with the Gold Rush provided the inspiration for a tale of resilience and exploration. Much of the story takes place in Alaska, traveling between Dawson and Skagway. The discovery of gold prompted a mass exodus to the Klondike, where gold was hypothetically free for the taking. The town of Dawson became the heart of the Gold Rush; for in 1886, Captain Moore, a citizen of Canada who had been prospecting for gold in the Canadian northwest, discovered a trail he called the "White Pass." This trail allowed for the transportation of supplies, correspondence, and men into the Alaskan interior, and it lead directly to Dawson.
