Clearing snow from Colorado's high mountain passes isn't a job for the faint of heart. As you can tell in this video.

This video is a couple years old, but it shows just what it takes to clear the Jeep trail over Imogene Pass.

Imogene Pass connects Ouray with Telluride, and tops out at 13,117 feet. As you can see, this bulldozer is clinging to the side of a mountain cliff. No. Thank. You.

When the road is clear, the trail isn't recommended for novice drivers. That must mean the driver of this bulldozer has cajones of steel.
