Coinciding with the population growth of Southern California in the 1920s, hikers and ski enthusiasts began using Big Pines, an area near the present day Mountain High resort.

In 1929 the construction began on the world's largest ski jump of that time in an attempt to attract the 1932 Winter Olympics.

Due to several years of poor snow conditions and a lack of snowmaking equipment, it was sold in 2004 to the owners of Mountain High.

Lift tickets purchased at any one of the areas are good at the other two, and a shuttle normally operates between the west and east resorts, ferrying skiers and snowboarders back and forth.

At 6,600 feet (2,000 m)-8,200 ft (2,500 m) the East Resort has longer runs and more open terrain providing a more alpine snowsports experience.

[10] Due to its daily sun exposure and lower base elevation, 100% of the resort has snowmaking capabilities using both the compressed air/water gun type and large water/fan units.

At 7,200 feet (2,200 m)-7,800 ft (2,400 m) the North Resort is dedicated to mainly beginner and intermediate terrain and snow play.

In recent years, the North Resort has remained closed for skiing and snowboarding, because Mountain High has yet to install a snowmaking system there, causing them to rely on natural snowfall for a substantial snow base.

These campgrounds are located in the Angeles National Forest and camping is only open during the summer months, starting in May.
