Refound for benchmarking contest. Still a tranquil spot.

Found it!® Eight of ten or so for the day. Very nice garden. Bear walked right up to this one!

Found by description and coordinates. Pretty garden here. The benchmark is incorporated in a Zen garden. Some developers care about such things.

From this one, I conclude that there aren't too many geocachers among cyclists (or vice versa): this benchmark is only 25 feet away from the busiest cycling route around!
Although there is a new POWER LINE, the old POLE NO. 60027 remains and still carries some wires!
The benchmark is in good shape, and the area is well maintained, kinda rock garden... worth visiting.

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.
