Trail Ridge Road Plowing

Plowing Trail Ridge Road begins in mid-April and takes approximately 6 weeks to complete, and is VERY weather-dependent. During plowing operations, the equipment is brought down below treeline overnight and road clearing begins anew each day. This is done because overnight storms can snow equipment in above treeline….an inch or two of snow can drift into several feet overnight. There are approximately 1500 snow poles on the park’s east side and at least 1500 on the west side, which are used to mark curbs, rock walls, signs, and any other obstacle that can cause damage to the rotary plow head, plus help direct the plow drivers across the vast drifted alpine tundra.
