"The first known crossing of this pass by a 'white man' was made in 1864 or 1865 by an employee of the Hudson's Bay Company, who started at Fort Selkirk and was delivered by the Chilkoot [Indigenous People} to Capt. Swandson [sic], commander of one of the company's steamers. The first expedition to cross the pass was that of George Holt in 1875, who travelled from Lynn Canal to the headwaters of the Yukon River. With the discovery of gold in the Yukon in the 1870's, this pass was used by many prospectors, and during the Klondike Gold Rush in 1896 the Dyea-Chilkoot Pass route became one of the important routes to the gold fields."
