I recovered the U.S. Coast & Geodetic Survey triangulation station from 1948 in good condition. The station is located east of Highway 139 and on top of a small hill. A nearby metal witness post aids in station recovery. Reference marks 1 and 2 were located although RM 1 was found uprooted and the disk was bent up on one side. The Azimuth Mark was destroyed as part of a highway expansion project in 1990. This station mark is also located on a topography map as 'SCORPION'.

The posted NGS coordinates and datasheet description are acceptable for station recovery, although the community of Tionesta no longer exists.
