In the 1860s, a town called Montgomery filled the mouth of this massive valley at the base of Mt. Lincoln. At its peak, the town consisted of over 150 cabins and buildings, which are now buried under the waters of Montgomery Reservoir. The only thing left standing is the Magnolia Mill. You can’t miss it because the trail passes directly under it. The metal construction of the building would suggest that it was modernized and used at a later date.
