 It was opened on December 21, 1963, as "Treasure Mountain" by United Park City Mines, the last surviving mining company in Park City, with funds from a federal government program meant to revive the economically depressed town.When it originally opened, it boasted the longest gondola in the United States, as well as a double chairlift, a J-bar lift, base and summit lodges, and a nine-hole golf course.A special "Skier's Subway" was used to transport skiers nearly into the mountain through the pitch-black Spiro Tunnel on a mine train, where skiers then boarded a mining elevator that lifted them to the surface, from there they had access to the entire mountain.
