(12 inches). There have been limited studies regarding the effectiveness of the current management plan with respect to an adequate snow depth that would minimize the potential impact motorized winter recreationalists have on this seasonal habitat. Summer activities on the pass include the increasingly popular "Run Rabbit Run" 50 mile or 100 mile trail run. The area offers many car camping spots and hiking trails. One of the most popular summer sports to take place on the pass is road biking. Steamboat Springs often hosts a stage of the USA Pro Cycling Tour. This international bike competition takes riders up and over the pass descending into Steamboat Springs during end of a stage, and ascending over the pass during the beginning of the next stage. The pass also hosts the "Ride the Divide" Mountain bike race that takes place from Montana to Mexico every year. The trail over the pass begins at 10,038' (3060 m) at Base Camp Trailhead and ends at 9250' (2819 m) in the Medicine Bow National Forest, WY. The trail is 68.1 miles (99.5 km). This trail offers outstanding views east into North Park and west towards Utah. Users need to be prepared for weather extremes at all times. Somewhat unusually, the highway over Rabbit Ears Pass has a gently rolling character in the vicinity of the summit. After crossing the Divide westbound, the road dips briefly and then reaches its highest point (about 9426 ft) before descending gently to the west summit (9400 ft) and then dropping steeply (6.8% N) toward Steamboat Springs. This is the 28th steepest pass in the State of Colorado. The steep grade necessitates many sharp curves because of the steep rise of 3,000' in the seven mile descent into the town of Steamboat Springs. There is a single runaway truck ramp on this last stretch for truckers whose brakes become hot while descending the grade. The highway is significantly less steep on the eastern side of the pass, where it descends along a slow incline towards Muddy Pass. The current crossing of the Divide represents a realignment of the highway from a somewhat higher crossing just to the north. Access to Old Rabbit Ears Pass can be achieved by turning north off U.S. 40 toward Dumont Lake. The old summit is marked with a stone monument. The old highway is now Grand County Road 199. From the old summit, it
