ABOVE MHW ATOP AN ORANGE AND WHITE HORIZONTAL BANDED ì PIPE SECURED TO A SUNKEN BARGE IN 100 FT. OF WATER IN REPORTED ì POSITION 1350 YARDS, 271 DEGREES FROM GREAT SALT POND OUTER END ì LIGHT; PA LAT 41-11-58N, LONG 71-36-27W. LNM40/77--1ST CGD; 9/7/77; LIGHT HAS BEEN DISCONTINUED; TELECON ì WITH CG, 10/18/77, STRUCTURE REMAINS; CHARTED AS POLE.

EXAMINATION OF SIDE ì SCAN RECORDS DURING OFFICE PROCESSING FOUND TWO EXTREMITIES ì PROTRUDING OUTWARD AND UPWARDED FROM THE HULL OF THE SUNKEN ì BARGE. OFFICE PROCESSING WAS UNABLE TO TO DETERMINE THE HEIGHT OF ì EXTREMITIES DUE TO THE SONARGRAM ASPECT. THE BARGE HAS A COMPUTED ì HEIGHT OF 2.6M (8 FT) IN DEPTHS OF 96-98 FT. ECHOSOUNDER DEVELOPMENT ì ON BARGE WAS NOT CONSIDERED ADEQUATE FOR DETERMINING LEAST ì DEPTH.
