When Did Mammoth Mountain Ski Resort Open?

Mammoth Mountain Ski Resort is one of the most iconic ski resorts in the United States. Located in the Eastern Sierra Nevada mountain range, Mammoth Mountain has a long and varied history that dates back to its official opening in 1953.

Mammoth Mountain was originally founded by Dave McCoy, who was an avid skier and former member of the U.S. Army’s 10th Mountain Division during World War II. After returning from the war, he settled in Mammoth Lakes, California and began exploring the local mountains. He quickly recognized the potential of developing a ski resort on Mammoth Mountain and set out to make his dream a reality.

The first ski lift at Mammoth Mountain was installed in 1953 and it quickly gained popularity among local skiers and visitors alike. The resort grew steadily throughout the 1950s and 1960s, with additional lifts being installed as well as lodges for visitors to stay at. In 1978, Mammoth Mountain became part of the Intrawest Corporation which invested heavily in modernizing and expanding the resort.

Today, Mammoth Mountain Ski Resort is one of the largest ski resorts in North America with over 3,500 acres of terrain spread across 11 different peaks. With its expansive terrain, incredible views, modern facilities, and top-notch customer service, it’s no wonder why Mammoth remains one of the most popular winter destinations for skiing and snowboarding.
