The Rocky Mountain Cup is a soccer trophy contested between Real Salt Lake and the Colorado Rapids. The cup is awarded by the Committee of 10, a group of bi-partisan fans who run the competition, to the team with the most points in games played between the two. The teams are awarded 3 points for each win and 1 point for each tie in regular season MLS games against each other. The Cup is awarded at the conclusion of the deciding game of the series between the two teams.
If the teams end the season in a points tie, the team with the most goals on aggregate will win (for a two-team competition, this is equivalent to goal differential). If the teams are tied on aggregate goals, the current holders retain the Cup for another year.
The cup was created in 2005, the first year of play for Real Salt Lake.
