Caribou Ranch was a recording studio built by producer James William Guercio in 1972 in a converted barn on ranch property in the Rocky Mountains near Nederland, Colorado, on the road that leads to the ghost town of Caribou. The studio was in operation until it was damaged in a fire in March 1985.[1] The ranch hosted some of the most prominent acts of the 1970s and 80s and was closely associated with the band Chicago, who recorded five consecutive albums there between 1973 and 1977.
