Hi. I'm heading out in 2 days in central colorado and the road to the trailhead is marked as Four Wheel Drive Road on my Trails Illustrated. I'm trying to figure out what that means cause I'm not sure if I can make it to the trail head, and it's a long road! What is the difference between High Clearance Road and Four Wheel Drive Road, as designated on TI maps? I have an AWD car with 8.7 inches of ground clearance and I've successfully drive a "high clearance road" as TI designated it.
The road is FS 721 in Gunnison Ranger District for those that may know the condition. Thanks!!!!
