Snowbird: The resort opened in December 1971 with three lifts, the tram, the Snowbird Center and one lodge. Over the next three years it would add three lodges. In 1986, the resort renovated and expanded its main overnight center, the Cliff Lodge. In 1997, Snowbird entered the high-speed era by introducing the Gadzoom lift in Gad Valley. The next big step was to expand its skiable acres in 1999 with the opening of Mineral Basin on the back side of Bald Mountain.

Solitude: Story has it that while skiing one day at Alta, Robert Barrett was denied access to a restroom. So he built his own resort. He started construction in 1956, and the resort opened in 1957. After an exchange of owners, a former member of the Solitude ski patrol purchased the area and started it on the road to world recognition. Dave DeSeelhorst purchased the resort in the late 1970s and continued the process, making it the first resort in Utah to introduce skiers to the now-popular high-speed quad in 1989.

Snowbasin: The suggestion was to build a resort in Wheeler Basin, the current location of Snowbasin. More than 1,100 entries were submitted in a naming contest and Snowbasin was selected. Snowbasin officially opened in 1940 after the road was completed, with two rope tows up Becker Hill, site of the current Becker chairlift. After one change in ownership, Earl and Carol Holding purchased the troubled ski area in 1984, along with the Earl Miller Ski School. Holding turned the ski area around, making major improvements in lifts and slopes and lodges.

Sundance: It was back in 1901 that the family of S. Paul Stewart purchased the land where the ski resort is now located. They paid a whopping $2.50 per acre. Skiing started around 1946 when Raymond Stewart installed a rope tow and began calling the ski area Timp Haven. The resort was unique in the ski industry because it closed on Sunday. In 1957, Junior Bounous bought into the ski area and started a ski school. In 1963, Robert Redford built a home near the resort and took up an interest in getting into the ski business. He purchased the resort in 1968.

Wolf Mountain: The resort, formerly Nordic Valley, is both Utah's smallest and largest. All 110 skiable acres are lit up at night, which makes it Utah's largest night skiing/snowboarding operation. The first lift opened in 1971. A second started running in 1972. In 2005, Wolf Creek Resort, a nearby community of upscale condominium lodging, completed negotiations to buy the resort.
