[5]: 1 Until 1920, "Stewart Flats" was connected to the wider world by a single unpaved road with a grade of 18 to 20 degrees on the last half mile.

In the early 1920s, the Utah County Commission built an automobile road that passed through "Stewart Falls" as it connected the towns of Aspen Grove and Wildwood.

In 1922, the Forest Service over the Wasatch National Forest, part of the United States Department of Agriculture, requested to put in a trail that crossed part of the property owned by the North Folk Investment Co,[7] The Stewart family appreciated the hikes since they brought more popularity to the area.

[5]: 26  Today, the trails around the Sundance Mountain Resort offer views of North Fork and Stewart Falls.

Ray Stewart was responsible for clearing and developing the Timp Haven Ski Resort and contributed to the original rope tow used.

Hilda Stewart, Paul's wife, had a cafe on the resort property and served hamburgers and other meals to ski guests.

The Timpanogos Mountain Club persuaded Daniel to bring the tow to North Fork Canton.

Ray Stewart bought the truck and equipment and overhauled it to create a working tow to run on Saturdays and Sundays.

In addition, When Timp Haven opened, the creek was closer to the hill than it is today, so skiers had to make a quick turn at the bottom to avoid falling into the water.

[13] Ski classes at the resort were started by Jessie Scofield, the supervisor of Provo City Recreation, in the winter of 1946.

Professors at Brigham Young University also started ski classes, bringing buses of students in the afternoons.

[15][16] The first double chairlift was installed in the fall of 1965 and replaced the lower single chair and an upper T-bar, vertically climbing 1,400 feet (430 m).

[18] The resort continued expanding, however, and a lodge was built in 1957 (whose foundation is under the General Store and Grill Room today).

In order to increase revenue, Redford wanted to create an Aspen-like atmosphere and use the resort to promote the arts and draw in Hollywood stars.

[21]: 11 In November 1979, Redford held a 3-day conference for filmmakers and professional artists at the Sundance Mountain Resort.

[26] He was reluctant to take control of the festival, and in its early years, it was "regarded by many [film] distributors as toxic".

[citation needed] Several notable people have owned residencies in the Sundance Resort properties, including Sydney Pollack, William Devane, and Daniel Melnick.

As part of the sale, Broadreach and Cedar have committed to continue Redford's policies of responsible development and land preservation.

The resort terrain climbs 2,150 vertical feet (655 m) up the northeast slope of Mount Timpanogos, reaching the crest of the ridge at Bearclaw Cabin.

This restaurant at the resort's apex of 8,250 feet (2,515 m) provides spectacular 360° views of the surrounding landscape, and of Mount Timpanogos as it rises to a height just short of 12,000 ft (3,660 m).

The front side portion was replaced by a high speed quad, known as the Outlaw Express, running on an alignment previously used by the Mandan double chairlift that Ray's replaced, with a mid-unload station below Marmot Gulch to service beginner terrain that had been accessible from the winter mid-station on Ray's.

The backside portion was replaced with a new fixed grip quad called Stairway, running from the bottom of Red's to the Mandan summit.
