Stonewain Valley
From Tolkien Gateway
A long straight valley in the eastern White Mountains. It was made in ancient days by the Men of Gondor, as a route from the quarries beneath Nardol to Minas Anor. By the time of the War of the Ring, it was all but forgotten, but it was rediscovered in time to be used by the Rohirrim to come to the Battle of the Pelennor Fields.
