Webster is a well preserverd furnace with the very unusual feature of becoming octagonal about half way up.
On Bear Run a branch of Pine Run, Rockland Township. At the village of Van on US322 just east of the bridge over East Sandy Creek turn south on Tarklin Hill Road (T582). Proceed 2.0 miles to its junction with Georgeville Hill Road (T381). Turn right and cross a small bridge. Continue 0.3 miles until the road makes a sharp turn to the left and a rough lease road goes straight ahead. Park here 41º 17.478'N - 79º 39.723'W. Walk the lease road for about ¾ miles. At this point the lease road makes a sharp right turn at the bottom of the hill. The furnace is to the right between the road and the hillside.
