1 <br /> Mineral Survey No. 20925 <br /> Fitt <br /> This survey was made with a WILD T-1 Theodolite, No. <br /> 213124, with a vernier micrometer reading to 6 seconds <br /> of arc: an automatic vertical circle index and self- <br /> contained optical plummet. The instrument was in good <br /> condition at the time of the survey and all <br /> adjustments were in good order. <br /> All azimuths in this record were determined by the <br /> method of deflection angles referred to the meridian <br /> determined by the following observation: <br /> July 31, 1991, at transit station "TP-2" in latitude <br /> 39° 10' 53" N. and longitude 106° 49' 14" W. (NAD <br /> 1927) , as determined from the United States Geological <br /> Survey quadrangle map "ASPEN COLO," 1960, elevation <br /> 8720 feet above sea level and temperature 60•, make a <br /> series of six altitude observations on the sun for <br /> azimuth at approximately equal time intervals, three <br /> each with the telescope in direct and reversed <br /> positions, observing opposite limbs of the sun, and <br /> reading the horizontal angle from a reference point <br /> (transit station "TP-1") to the sun. <br /> Mean time of observation, 105th meridian, mountain <br /> daylight time - 911 36" 30' a.m. <br /> Declination of the sun at mean time of observation <br /> 18° 17' 05" N. <br /> Mean observed vertical angle to the sun's center <br /> 38° 21' 42" <br /> Mean horizontal angle from reference point to the <br /> sun's center m 181° 29' <br /> True bearing to reference point = N. 84° 05' W. <br /> The deflection angle from reference point to Cor. <br /> No. 3 ENMA No. 2 lode m 62° 36' right. <br /> The lines were measured using a LIETZ RED 2 electronic <br /> distance measuring meter, No. 22378, with an effective <br /> range of 10,000 feet and three (3) Lietz round retro <br /> prisms. A Lufkin steel tape, 301 feet in length, <br /> graduated every foot for the full length and in tenths <br /> and hundredths for one foot. The instrument, mirrors, <br /> and tape were all in good condition at the time of the <br /> survey and were compared to a standard distance at the <br /> time of beginning the survey, and found to be correct. <br /> For 960040(November I I7)USDI-ILU MINI*AL SURVEY fIELD NOTE PAPER <br />
