Trail Ridge Road is scheduled to open this Friday for Memorial Day weekend. According to Ski Hi News, Rocky Mountain National Park Officials will hold a ribbon cutting ceremony on Friday at noon to inaugurate the summer opening. The 48 mile long road connects Grand Lake, Colorado to Estes Park. Trail Ridge Road is the highest contiguous paved road in the US with a summit elevation of 12,183 feet.
Trail Ridge Road is in a microclimate of Colorado that receives large amounts of snowfall. While the total snowfall numbers are hard to estimate, another Sky Hi News article articulates that it is in the hundreds of inches which are solidly compacted by a combination of driving winds and below freezing temperatures.
