The “Iron Curtain” between Slide and Rose finally came down in 1987 when Mt. Rose acquired the Slide Mountain Ski Area terrain under a lease agreement with the U.S. Forest Service. The “Slide Side” (as it is affectionately referred to by locals) became the East Bowl of Mt. Rose. The combination of the two ski areas increased the overall terrain of Mt. Rose to 900+ acres and established the resort as a significant player in the Lake Tahoe Basin.
