From the Guidebook:
The VIII Olympic Winter Games
of 1960 commemorated a century of sport skiing in California.
By 1860 the Sierra Nevada-particularly at the mining towns
of Whiskey Diggings, Poker Flat, Port Wine, Onion Valley,
La Porte, and Johnsville, some 60 miles north of Squaw
Valley-saw the first organized ski clubs and competition
in the western hemisphere.
