An experienced ski patroller in Aspen, Colorado, has claimed that the first panty tree was under the Bell Mountain ski lift at Aspen Mountain in the early 1980s. A discussion in 2006 in the letters pages of the Skiing Heritage journal said "it is believed" that the practice might have begun in the late 1950s. This panty tree was soon copied at nearby Vail Ski Resort and then numerous other ski areas across North America.
The first panty tree in Vail was found chopped down one morning in 1997, but skiers picked another tree to continue the tradition. This second tree was used in a 2005 liqueur company advertisement, which stated, "You just recognized a pair of panties in the Sun Down Bowl tree...The conversation is waiting." In 2010, this tree was also chopped down to make way for a new ski lift.
