From the Snow King Mountain website:

In 2014, Snow King celebrated its 75th ski and snowboarding season. Since 1939, Snow King Mountain Resort has played an important role in recreation, commerce and community development in Wyoming and Jackson Hole. As Wyoming’s and Jackson Hole’s first ski area, Snow King paved the way for similar winter resorts on Forest Service land in the Wind River, Bighorn and Medicine Bow mountains. Within Jackson Hole, the development of Snow King fostered a community culture built around the enjoyment and skill of winter sports, which eventually made Jackson Hole an international ski destination.
