Harrowdale

Harrowdale was the name given to the deep north-south valley cut out of the White Mountains by the Snowbourn River. At its southern end, beneath the mountain known as the Starkhorn, stood Dunharrow, a great refuge of the Rohirrim. At its northern end, where the Snowbourn issued onto the plains of Rohan, stood that nation's capital, Edoras.

It was in Harrowdale that the muster of Rohan took place before Théoden led his riders to Minas Tirith.
