McCrea (aka Olney) - Is along Mahoning Creek in Wayne Township. It was built in 1857 by McCrea and Galbraith about one mile below the Mahoning Dam. It is in poor condition, but with a well preserved retaining wall or loading dock below the remains(s&t). We photographed this site.(P)(V)(rp-1978-2004)
Go north from Kittanning on PA28 to Goheenville. About 3/4 mile beyond the bridge at the north end of the village turn right on Calhoun School Road (SR1016). Follow this road 3 miles, turn left on Crosscut Road (SR1025) for about 1.3 miles. Turn right on Pat Road and then right again on Furnace Road (T667). Follow this road to the bottom of the hill.

About 200 feet along this road you will see a stone wall at the base of the hill on the left. 40 55.520'N - 79 17.449'W. The furnace is on the hillside above the wall.
