Found it at 12:45, 08 February 2003. Found it as described and in good condition. The building is no longer used as a library, but houses the County Planning, Engineering, and Surveyor's offices.

WGS84 coordinates found by 4 minute occupation with 6 strong satellites and 0 WAAS satellites (proximity to the building blocked the WAAS signals).

Benchmark detail.


Benchmark detail. Mark is in excellent condition - the fact that it's in front of the door to the County Surveyor's office may have something to do with that.


The benchmark and the GPSr.


The front doors and a plaque remembering the building's use as a library.


The old library; now the County Engineer's & Surveyor's offices.
