[2] Deer Valley was one of the venues for the 2002 Winter Olympics, hosting the freestyle moguls, aerial, and alpine slalom events.

The first ski lifts appeared in 1946, when local residents Robert Emmett Burns, Sr. and Otto Carpenter constructed them, largely from nearby lodgepole pines.

In 1984, the Mayflower triple was built, creating an additional pod of expert terrain on Bald Mountain to the east of Sultan.

In 1991, Deer Valley's first high speed quad was built by Yan to replace the Carpenter triple on Bald Eagle Mountain.

That same year, the resort expanded onto Flagstaff Mountain with Yan building two triple chairlifts: Red Cloud for lapping the new intermediate and advanced trails, and Viking to provide egress from the area.

In 1993, Deer Valley added its second high speed quad and first from Garaventa CTEC with the opening of the Northside Express, running to the summit of Flagstaff Mountain and servicing a new pod of intermediate terrain.

Also in 2004, an additional triple chairlift, Judge, was built to supplement Viking in moving guests from Flagstaff Mountain to the Silver Lake base.

Sultan was replaced with a high speed quad in 2005, with the lift being extended downhill so that a catwalk could be built, making it directly accessible from the Silver Lake lodge without having to ride Sterling or Wasatch.

In 2007, the resort expanded onto Lady Morgan Peak, to the north of Flagstaff Mountain, with a new 200 acre pod composed of nine trails and additional gladed terrain serviced by its own high speed quad.

[8] In 2012, detachable chairlift service was added to Little Baldy Peak with the replacement of Deer Crest with a Doppelmayr high speed quad, known as the Mountaineer Express.

[9] Deer Crest was relocated to Crystal Mountain Resort in Washington, where it opened in 2014 to replace a Riblet double chairlift.

[10] In August 2017, Deer Valley was sold to the newly formed multi-resort entity, Alterra Mountain Company, a joint corporation composed of KSL Capital Partners and Intrawest Resort Holdings, LLC.

During the 2002 games Deer Valley hosted the freestyle moguls and aerials, and alpine men's and women's slalom events.

[18] It also hosted the men's and women's moguls and aerials events for FIS Freestyle Ski and Snowboarding World Championships 2019.

In addition, Deer Valley has received top 10 ratings in the categories of snow, lifts, weather, apres-ski, off-hill activities, access, dining, on-mountain food, and overall satisfaction.

[32] Deer Valley is one of three remaining American ski resorts that prohibit snowboarders along with Alta and Mad River Glen.
