While snowmaking was old news in the midwest and southeast by the 1960s, resorts in the Rockies didn't think it would be worth the capital investment until decades after the first commercial snowguns were available in the 1950s. Sun Valley was one of the first, partially because it turned out that the location picked in the early 1930s has plenty of sun during the winter but not that much snow on a regular basis. The installation of snowmaking infrastructure started at SV in 1972. By 1976, 75 acres had snowmaking.
For context, my home hill in northern VA had 100% snowmaking when it opened in 1972. By the late 1979s after an expansion to the current peak there was 73 acres, with two runs on the upper mountain. Cataloochee, near Asheville, NC, opened in 1961 with 100% snowmaking on 50 acres.

While researching the 1976/77 drought year, I came across the article below in the Salt Lake Tribune describing the benefits of "Snow Augmentation" at Sun Valley (click to enlarge).
Published in late December 1976 when Utah resorts were not operating due to a lack of snow, it describes initial use of artificial snowmaking at Sun Valley. Today, Sun Valley probably has one of the best snowmaking systems in the world. At that time, during the great snow drought of 1976/77, it enabled three runs to be open for the holidays. As described in the article,
"Ribbons of artificial snow from two to three feet deep have been shot by air compressor-activated snow guns up to two-thirds of the way up the mountain."
It goes on describe the artificial snow as "cube like crystals" with "a bit more density than nature's snow." I'm sure that sounds familiar to today's skiers. The system sounded pretty cutting edge for the time, pulling 1400 gallons a minute and putting down two acre-feet of snow in eight hours.
