The first mural installed in the Elk Camp restaurant by the Aspen Art Museum and the Aspen Skiing Company was in November of 2012 ("The Hills Are Alive" by Dave Muller). The official dates for the mural were November 22, 2012-September 2, 2013. See this article for more information: https://www.aspenartmuseum.org/exhibitions/40-dave-muller
At the end of its run, it was replaced by a mural by Teresita Fernandez ("Golden Panorama").
