I made a loop hike out of this one. Went up Mill D North to Desolation Lake and then over the ridge to descend via Bear Trap Canyon.
The trail to the lake is fairly easy and the snow is almost gone. Lake is still frozen. Very beautiful. I was the only hiker at the lake.
The descend via Bear Trap is not for the faint of heart. lots of snow and the trail keeps disappearing. without the app I could not have found my way down the mountain. There's really not much to see that side of the ridge. I recommend that you turn around at the lake and go back the same way you came.
This will also save you hiking along Big Cottonwood Road for 1.5 miles to get back to your car.
