I recovered the U.S. Coast & Geodetic Survey triangulation station from 1948 in good condition. The station is located west of Highway 139. An orange, metal witness post aid in station recovery. Reference marks 1 and 2 were located but not the Azimuth Mark (which I believe to be either destroyed or buried under rock and dirt due to a highway expansion project in 1990). This station mark is also located on a topography map as 'MEARS'.
The posted NGS coordinates and datasheet description are acceptable for station recovery, although the community of Tionesta no longer exists and the telephone line is also gone.
NGS datasheet info for station mark:
