Located near the summit of Hoosier Pass off Hwy 9 is Montgomery Reservoir. At an elevation of 10,873 feet, this high altitude lake offers some dramatic views as it is surrounded by 14,000-foot peaks. Due to the winds that come down off the peaks, this reservoir is known to freeze over into solid blue ice in the winter. The reservoir and dam are owned by the City of Colorado Springs and permission must be obtained for filming.
