Opened in late 1973, Big Sky Resort has more than 5,800 acres (9.1 sq mi; 23.5 km2) of terrain and a vertical drop of 4,350 feet (1,330 m).

[1] In July 2013, Big Sky Resort acquired 200 acres (0.8 km2) on Spirit Mountain, which were previously owned by Spanish Peaks, a private club.

[2] Big Sky Resort also offers meeting space for conferences, weddings, and corporate retreats.

[3] The resort was founded by Montana native Chet Huntley, the retired co-anchorman of The Huntley–Brinkley Report of NBC News.

[2] The resort grew steadily over the following decades, adding lifts and more than tripling the terrain available for skiing and snowboarding.

The eighth lift at Big Sky was the Southern Comfort on the south side of Andesite Mountain, a Heron-Poma triple chairlift acquired from Copper Mountain in Colorado, installed in 1990 and upgraded to a high speed quad for the 2004-2005 ski season.

The Shedhorn double chair was also part of this expansion, installed in 1995 on the lower south face of Lone Mountain.

[2] In April 2000, Boyne Resorts announced that an estimated $400 million in improvements would take place over the next ten years to the Mountain Village and the ski area.

[2] In 2007, Big Sky expanded the skiing opportunities on the south face of Lone Peak with the reinstallation of the original Southern Comfort triple chairlift as the Dakota chairlift on the south side of Lone Peak, providing access to the accompanying out-of-bounds sidecountry, Dakota Territory.

In 2018, as part of the Big Sky 2025 plan, Doppelmayr built North America's first ever high speed eight pack in the form of the Ramcharger 8, which replaced an existing Doppelmayr high speed quad from the base area to the summit of Andesite Mountain and has many of the same features as Powder Seeker.

The original high speed quad was reinstalled on Lone Peak, where it replaced the Shedhorn double chairlift.

[7] In 2025, the ski resort features 39 lifts with an uphill capacity of 42,000 riders per hour, 320 runs of varying difficulty (21% beginner, 14% intermediate, 15% advanced intermediate, 31% advanced, 11% expert, and 8% extreme), a longest run of 9.66 km, and 5 terrain parks.
