Eight years since the last log and all is well! Had to clear a few dead weeds, but otherwise still looks great! Shadows were messing with my photos.

I found this PDH Marker, with no difficulty. It’s in terrific shape and exactly where it’s supposed to be, as described and photographed by Daclaren.

This one was an easy find and is in great condition. Disk is stamped N 161 1942. Description below is accurate with the following additions. The highway referred to as U.S. 15 is now called Old Harrisburg Road. The bridge and disk are located on Old Harrisburg Road, not on the newer U.S. 15. The disk is in the northwest wingwall of the bridge.

|RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1966
RECOVERED IN GOOD CONDITION.
- 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.
