Martha's Vineyard Loc 59A
Located on a steel girder Fire Tower (not a fire control tower) for watching forest fires. Not much is known about this site currently, but it served as an AAIS OP until the tower (built 1930) was dismantled in 1944 and brought to West Falmouth to replace the Fire Tower at Loc 58A in 1946. Loc 58A was also only for AAIS OP.
