Chilkoot Pass, elevation 1067 m, is situated on the BC-Alaska border. It was used by the Chilkat Indians, a tribe of the TLINGIT, expert weavers who traded with the Nahani along the Yukon River to the north and later with HBC employees. In 1883 the US government, unknown to Canada, sent an expedition to the Yukon via the pass to study the terrain and the Indian situation. Irritated by this action, the Canadian government sent William Ogilvie via Chilkoot in 1887 to establish the 141st meridian at the Yukon River. During the KLONDIKE GOLD RUSH, an estimated 20 000 to 30 000 people crossed the pass 1897-98. The NWMP established a post here to stop lawlessness, collect duty and ensure that each person had supplies for 1 year. Several tramways were built over the pass to Crater Lake 1897-98, but the trams and pass fell into disuse with construction of the railway over WHITE PASS, completed in 1900. A hiking trail, "Trail of 98," over Chilkoot was rebuilt in the 1960s, complete with shelters, as a joint venture by the Yukon government and US National Park Service.
