LU2202'
LU2202'IT IS 50.91 FEET OR 15.515 METERS BETWEEN REFERENCE MARK NO. 3
LU2202'AND REFERENCE MARK NO. 4.
LU2202'

LU2202
LU2202'RECOVERY NOTE BY US GEOLOGICAL SURVEY 1969
LU2202'THE MARK WAS NOT FOUND, BUT WHERE IT SHOULD HAVE BEEN, A ROAD
LU2202'HAD BEEN BUILT. THE MARK MUST HAVE BEEN DESTROYED AT THAT
LU2202'TIME. ALL OTHER MARKS REFERING TO STATION PRATT WERE FOUND.
