Winter Sports, Inc. (WSI) formed 78 years ago in 1947 as a public company of community shareholders, opened Big Mountain that December 14.

[2] It hosted the U.S. Alpine Championships in early March 1949,[3][4] where future Olympic champion Andrea Mead of Vermont won all three women's titles at age sixteen.

[13][14] In December 2006, WSI conducted a 15-for-one reverse stock split, further reducing to about 50 remaining shareholders in order to provide a tax advantage as a Subchapter S corporation.

[23][24] In September of that same year, the resort reversed the decision and announced that 2008–09 winter season passes would again convey unlimited foot-passenger lift access for summer 2009.

The backside has more tree skiing terrain, and additional terrain can be accessed by the Bigfoot T-Bar on weekends and during select holiday periods, as well as Flower Point (a used triple chairlift acquired from Kimberley Alpine Resort), and East Rim (a triple chairlift relocated from the Glacier View alignment), which services the eastern front side and East Rim.

The intermediate Hell Fire trail is the longest on the mountain; it runs 2.52 miles (4.06 km) from the summit to the base of Chair 8.
