ROCKY MOUNTAIN NATIONAL PARK, Colo. (AP) — A high-elevation road that traverses the Rocky Mountains in northern Colorado is closed after a rare summer blizzard left ice and deep snowdrifts.

Plows encountered drifts up to 8 feet (2.4 meters) deep on Trail Ridge Road in Rocky Mountain National Park Monday. The popular highway reaches 12,183 feet (3,713 meters) above sea level.

Park officials said the road will reopen once conditions improve but didn't say when that might happen.

Wintry weather that lasted through the spring and into summer has kept the road closed longer than normal this year.

The highway opened for the first time this season on June 5, about a week later than usual. Park officials closed it Friday after another late-season storm brought deep snow, high winds and below-freezing temperatures.
