" Terre Hill received an official nod by the United States Coast And Geodetic Survey, USC&GS, or just simply CGS, in the form of a permanent bronze marker in 1934. The Terre Hill survey markers have been officially recovered, or found, only four times since 1934. Unofficially the station has been logged three more times by geocachers using the NGS datasheets for reference. "
