This log is to provide some addition information, mainly additional GPSr coordinates, to the logs posted earlier by Rich in NEPA and Zhanna. Please see their logs for more complete info.
I used a Magellan Explorist 100 with the following map units: North Referance-Magnetic North, Map Datum WGS 84. These are the same units used on GEOCACHING.COM.

This mark was found as part of the recovery of station PROMISED, PID LY1163. Photos and description can be found on the [B][URL=http://www.geocaching.com/mark/details.aspx?PID=ly1163]PROMISED[/URL][/B] benchmark page.

[I]A report on the condition of this reference mark was submitted to NGS, along with the following recovery note:[/I]

Reference mark 1 was recovered in good condition. It is approximately 13.8 feet south of Rock Oak Trail. The steel witness post still exists, but the blazed tree was not found.

Reference mark PROMISED NO. 1 is set in the top of a square concrete monument nearly flush with the ground, roughly 13.8 feet south of the centerline of Rock Oak Trail. There is no blazed maple tree near the mark. (For photos and details how to reach this mark see: [B][URL=http://www.geocaching.com/mark/details.asp?PID=LY1163]LY1163[/URL][/B]) ~Rich in NEPA~

Control Text

  • The horizontal coordinates were scaled from a topographic map and have an estimated accuracy of +/- 6 seconds.
  • The orthometric height was determined by differential leveling and adjusted by the National Geodetic Survey in June 1991.
  • The geoid height was determined by GEOID99.
  • The dynamic height is computed by dividing the NAVD 88 geopotential number by the normal gravity value computed on the Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45 degrees latitude (g = 980.6199 gals.).
  • The modeled gravity was interpolated from observed gravity values.
