A great spring and fall loop. Head up alexandar to the wildlife bridge over i-80, climb up to the radio towers, then take the sheep trail over to big mtn pass, then head down mormon pioneer trail and then back down highway to alexandar starting.

Ran from where U65 crosses Big Mountain Pass south to Bald Mt. Still lots of beautiful flowers blooming: penstemons, columbines in the shady areas, sego lilies on the summit of Bald Mt. Trail just a little drier than perfect. What wasn't so nice was all the down trees across the trail. About 1¾ miles south of the highway a very solid tree about two feet in diameter is across the trail. Whoever clears this will have some work to do. From about the 2 mile mark almost to the summit of Bald Mt. there are numerous trees of more manageable size across the trail. If you do this section plan to spend a lot of time climbing over trees.
