Noted ski film producer Warren Miller, while in his early twenties, wintered in Sun Valley from 1946–49, first living in a car and small teardrop trailer in the River Run parking lot.
One of these friends was Edward Scott, the future inventor of the lightweight aluminum ski pole.
This extra cash helped Miller purchase his first rolls of 16 mm movie film, to start his motion picture career.
Seven chairlifts were added, and the number of trails increased from 33 to 62.
The first two double chairs on Warm Springs were installed in series in 1965; Bill Janss bought out his brother's share of the resort and gained full control of Sun Valley in 1968.
Among skiers, the term "Sun Valley" refers to the alpine ski area, which consists of Bald Mountain, the main ski mountain adjacent to Ketchum, and Dollar Mountain, adjacent to Sun Valley, for novice and lower intermediate skiers.
Bald Mountain, or "Baldy," has a summit of 9,150 feet (2,790 m) and a vertical drop of 3,400 feet (1,035 m).
During this time, he evolved from ski bum, to ski instructor, to ski filmmaker.
Miller has traveled and filmed all over the world, but until recent years, he continued to return to Sun Valley virtually every year.
Sun Valley is a resort city in Blaine County in central Idaho, in the western United States.

Navy (Pacific Theater), which was operational in July 1943.
