HISTORY
CL111/1919--SUNKEN ROCK REPORTED, CHAS. LORENTZEN, MASTER OF ì
THE SHIP ST. PAUL, BELONGING TO THE NORTHWESTERN FISHERIES COMPANY, ì
REPORTS THAT HIS VESSEL WHILE AT ANCHOR OFF KENAI, AK. 26 APRIL ì
1919, STRUCK A PINNACLE ROCK WITH AN ESTIMATED DEPTH OF 16FT OVER ì
IT (VESSEL DRAFT AND TIDE ARE UNKNOWN). THE FOLLOWING ì
BEARINGS WERE PROVIDED: NW CANNERY AT KENAI....NE MAG. (72 TRUE); EAST FORELAND ì
POINT....NNW 1/2 W MAG. (358-30 TRUE). POSITION GIVEN IN LAT ì
60-31-24N, LONG 151-24-30W(VALDEZ DATUM). ROCK CHARTED AS PD. THE ì
VESSEL WAS SWINGING TO FLOOD TIDE, SOUNDINGS WERE TAKEN BUT ì
FAILED TO FIND OBSTRUCTION WITH THE LEAD. THE VESSEL UPON BEING ì
PUT IN DRY DOCK SHOWED THAT IT HAD SUSTAINED CONSIDERABLE DAMAGE.
DATUM SHIFT--NAD27 SHIFT APPLIED 1947 CHART EDITION; VALDEZ ì
DATUM TO NAD27, LAT +10.7'(333.6M); LONG -27.2'(412.4M)> LAT ì
60-31-34.7N, LONG 151-24-02.8W(NAD27).
CL1487/69--PRE. DATA OF H8789/64; INVESTIGATION OF SUNKEN ROCK ì
(PD) SHOWED NEGATIVE RESULTS. SOUNDING LINES SPACED AT 20 TO 110 ì
METERS WERE RUN IN A GRID PATTERN IN A ONE-HALF MILE STRIP. ì
HOWEVER, AS THE CONE OF THE ECHO SOUNDER SIGNAL (RAYTHEON/723) ì
WOULD COVER A WIDTH LESS THAN 15 METERS IN DEPTHS OF 7 TO 8 ì
FATHOMS, A PINNACLE ROCK COULD EASILY ESCAPE DETECTION IN THIS ì
INVESTIGATION. ROCK NOT CONSIDERED DISPROVED.
CL611/75--FAIRWEATHER-SPECIAL ROCK INVESTIGATION(1974); FA ì
CONDUCTED A 1/2 MILE SQUARE ECHO SOUNDER INVESTIGATION ABOUT THE ì
CHARTED POSITION USING A ROSS FINELINE 5000 ECHO SOUNDER. THE 1:5000 ì
SCALE SURVEY WAS CONDUCTED AT 50 METER LINE SPACING AND INCLUDED A CENTRAL ì
PORTION 1/4 MILE SQUARE SOUNDED AT 25 METER LINE SPACING. NO ì
INDICATION OF A SUBMERGED ROCK WAS DETERMINED. HYDROGRAPHER ì
INDICATES THAT THE 1919 GROUNDING PROBABLY OCCURRED ON THE SHOAL ì
AND ROCKS ONE MILE EAST OF THE REPORTED POSITION. HYDROGRAPHER ì
RECOMMENDS A WIRE DRAG SURVEY TO DISPROVE ROCK, BEFORE DELETING ì
FROM CHART.
CL2133/75--DAVIDSON-SPECIAL WIRE DRAG ROCK INVESTIGATION(1975); ì
"EXCESSIVELY STRONG CURRENTS, NO SLACK WATER, MARGINALLY ADEQUATE ì
TOWING VESSELS, AND WIRE DRAG GEAR DESIGNED FOR TOWING AT LESS ì
THAN 1.5 KNOTS ARE CONTRIBUTING FACTORS WHICH RENDER A SAFE, ì
EFFICIENT INVESTIGATION IMPRACTICAL. THIS FEATURE WOULD BE BETTER ì
PROVED OR DISPROVED USING SIDE SCAN SONAR TO LOCATE THE ROCK OR ì
TO DECREASE THE SIZE OF THE AREA TO BE WIRE DRAGGED." ATTEMPTS ì
WERE MADE WITH STANDARD WIRE DRAG GEAR; A 1500FT DRAG, FOUR ì
INTERMEDIATE AND TWO END BUOYS WITH 300 FOOT GROUNDWIRE SECTIONS ì
BETWEEN BUOYS. THE DRAG WAS SET TO MAINTAIN A SIX FATHOM DEPTH. WITH ì
THE FOULING OF THE BUOYS, ATTRIBUTED TO STRONG CURRENTS, THE PROJECT WAS ì
ABORTED WITH THE CONCURRENCE OF THE PACIFIC MARINE CENTER.
H8789/64--PATHFINDER-REVIEWED MAY 1980; ROCK INVESTIGATION NOT CONSIDERED ì
ADEQUATE TO DELETE ROCK FROM CHART. THE 1974 FAIRWEATHER ECHO SOUNDER ì
INVESTIGATION AND THE 1975 DAVIDSON WIRE DRAG INVESTIGATION WERE ì
CONSIDERED IN THIS RECOMMENDATION. (ENTERED 2/95 RWD)
H10617/95-- ROCK (SUBM 2.1FMS AT MLLW), POSITION GIVEN IN LAT ì
60-31-06.77N, LONG 151-24-40.64W (NAD83). (UPDATED 8/96 RWD)
