The former Ski Lift No. 1 begins on Aspen Street in Aspen, Colorado, United States, and climbs up the slopes of Aspen Mountain. It was built in the late 1940s on the site of Aspen's first ski lift, known as the Boat Tow. In 1990 it was listed under that name on the National Register of Historic Places, one of only two ski lifts in the country so recognized.
