During the summer months, drivers can travel on Trail Ridge Road in Rocky Mountain National Park from Estes Park on the east side of the park to Grand Lake on the west side of the park and back.
The road gives motorists stunning views of the Rockies well above treeline (the road rises to 12,183 feet), and it crosses the Continental Divide.
Road crews often try to clear all the snow before the Memorial Day weekend, but this year an unusually large mid-May snowstorm made that impossible.
