Two trees down. One is within the soon to be rerouted section and the other is further out, before the Imperial intersection. Both are a bit too large for a hand saw.

Trail in great shape. One tree across the trail at about 6 ft high 1.0 mile up from the Lodgepole trail junction. Hikers, bikers, moto riders can get under it. Horses need to drop down hill to get around it (sketchy).
