North Adams is located in the valley created by the Hoosic River, which has been walled and floored with concrete in portions to prevent floods. The city's Natural Bridge State Park contains the only natural white marble bridge in North America. Formed by glacial melt by 11,000 BCE, the arch and abandoned quarry have long attracted attention from hikers, including Nathaniel Hawthorne in 1838, who wrote of it (among other local features) in his An American Notebook. To the east, the city is bordered by the western face of the Hoosac Range, with visibility on its West Summit extending throughout the tri-state area. To the southwest, the city has the northern end of Mount Greylock State Reservation, ending at Mount Williams, which at above sea level is the highest point in the city. The Appalachian Trail passes through the western part of the city, crossing the summit of Mount Williams and briefly passing through Williamstown before heading north towards Vermont.
