Stamping Creek provided waterpower for this gristmill, as it had for a 1778 predecessor mill near this site. Above a solid stone foundation, the rectangular, heavy-timbered building, covered in siding, stands two and one-half stories tall, its gable end facing a curve in the highway. At the rear, the large metal waterwheel, 25 feet in diameter, rises to the second-story window level. The mill operated more or less continuously until at least 1948. Although it was then used for grain storage for years, most of its machinery survived. McNeel Mill has long been regarded as a landmark, and Washington, D.C., artist Dorsey Doniphan used it as the subject of one of two WPA-era paintings in the Marlinton Post Office. The Pocahontas County Historical Society began restoration in the 1980s.
