Natural Feature Along A.T. in Vermont

The Barre Montpelier Times Argus of 12 August 2007 has an article titled "A rocky stairway to heaven" and written by Andrew Nemethy. The article describes a hike at a place called White Rocks. Nemethy describes this as

"Vermont's biggest rock pile, a spectacular ancient waterfall of craggy boulders that David Lacy, a forest archaeologist for the Vermont national forest, calls 'rare and unique' and unlike anything else in the state."

Furthermore, this area is a "slope of jumbled Cheshire quartzite, which rises up to meet the top of a tree-covered cliff that is crossed by the Appalachian Trail." Where is it? East of Wallingford, VT on route 140 about 2 miles, the turn right on Sugar Hill Road.
