KEYSTONE, Colo. — Ski season is officially under way in Colorado.

The Arapahoe Basin and Loveland ski resorts opened Wednesday with one run each. Both say they have an 18-inch base of manufactured snow.

Arapahoe Basin announced Monday that it would open with one lift running at 9 a.m. Wednesday, prompting Loveland to announce it would also open that day but a half hour earlier. Both later agreed to start at 8:30 a.m. to share the title of being the first in the nation to open.

Arapahoe Basin was the first to open the last two seasons.
