The second is meteorology. Loveland and Arapahoe Basin are cold resorts compared to those in Utah owing to their high base elevations (each ~10,800 feet) and more interior location. In Utah, only the very top of Snowbird reaches to 10,800 feet (the top of the tram is a shade under 11,000).
At about 11,000 feet in the Colorado Front range, the average minimum and maximum temperatures in October are 21F and 43F. At 8800 feet in the Wasatch they are 30F and 49F. The lower altitudes and warmer temperatures make snowmaking more difficult in Utah during October. Fortunately, Mother Nature more than makes up for it by giving us far more natural snow during the course of the winter.
