Skookum Jim Mason, George Carmack and Dawson Charlie discover gold in a tributary of the Klondike River in Canada, setting off the Klondike Gold Rush.

Keish, also known as James Mason and by the nickname Skookum Jim Mason, was a member of the Tagish First Nation in what became the Yukon Territory of Canada. He was born near Bennett Lake, on what is now the Yukon–British Columbia border. He lived in Caribou Crossing, now Carcross, Yukon.

George Washington Carmack was an American prospector in the Yukon. He was originally credited with registering Discovery Claim, the discovery of gold that set off the Klondike Gold Rush on August 16, 1896. Today, historians usually give the credit to his Tagish brother-in-law, Skookum Jim Mason.

Dawson Charlie or K̲áa Goox̱ [qʰáː kuːχ] was a Canadian Tagish/Tlingit First Nation prospector and one of the co-discoverers of gold at Discovery Claim that led to the Klondike Gold Rush located in the Yukon territory of Northwest Canada. He was the nephew of Keish, also known as Skookum Jim Mason, and accompanied him on his search for his aunt, Kate Carmack. He staked one of the first three claims in the Klondike, along with his uncle and George Carmack. Storyteller Angela Sidney was a niece.

The Klondike River is a tributary of the Yukon River in Canada that gave its name to the Klondike Gold Rush and the Klondike region of the Yukon Territory. The Klondike River rises in the Ogilvie Mountains and flows into the Yukon River at Dawson City.

The Klondike Gold Rush was a migration by an estimated 100,000 prospectors to the Klondike region of Yukon in northwestern Canada, between 1896 and 1899. Gold was discovered there by local miners on August 16, 1896; when news reached Seattle and San Francisco the following year, it triggered a stampede of prospectors. Some became wealthy, but the majority went in vain. It has been immortalized in films, literature, and photographs.
