Little Mountain Trail
total distance = 7.3 mi
minimum elevation = 5816 ft
maximum elevation = 6882 ft
How to get there:
Ride up Emigration Canyon until the main road takes a u-turn, and a small side road comes in from the North. If you drove to this point, you can park your car on the small road. From here you ride up the road to the road summit. On the left side of the road, a dirt trail heads North. Proceed through the five gruelling climbs to the trail peak. Its all downhill from there with some intense rutty riding. Make sure to take a left when you come to the X in the trail. This will give you a long bomb down to the car (or out the canyon if you rode up on your bike).
Raw elevation data is located here. The first column is the elevation, and the second is distance traveled since the last data point. All numbers are in feet.
