Found this benchmark with PNWbrat and Bogey53 while geocaching. Beautiful views.

Found this benchmark with badger49 and Bogey53 after we hiked to the Lookout Mountain summit on a beautiful mid-January day. The view of Mt. Baker from the benchmark was spectacular today!

Found these 2 benchmarks w/ g8keepr and Mr. strapt4cache after a long hike

Found this puppy with hiking buddies imbedded in sandstone.

Found this and its friend while grabbing the Lookout Mountain, North Summit cache.

Hiked up today with Brewermd to find a nearby cache and what should I spot? Well this was a great bonus to add for the day.

Found this benchmark with the NCGS disk next to it after a hike up Lookout Mountain. It was too cloudy to get a great view from the summit but it was still a great hike. The disk is set an inch high from the surface of the rock outcropping but is stable.

THE SOUTH END OF THE MOUNTAIN OR RIDGE HAS A SUMMIT OF ABOUT THE SAME ELEVATION ABOUT ABOUT THREE - FOURTHS MILE SOUTH OF THE STATION, BUT IT IS HEAVILY TIMBERED. STATION MARK--A BRONZE - DISK STATION MARK SET IN A LARGE SANDSTONE OUTCROP. TWO DRILL HOLES IN THE SAME ROCK, CLOSE TOGETHER, ARE 1.1 METERS FROM THE STATION. THE US COAST AND GEODETIC SURVEY ESTABLISHED A FIRST - ORDER TRIANGULATION STATION ABOUT 0.2 METER SOUTHEAST OF THE ORIGINAL STATION MARK. THE USC AND GS STATION MARK IS A STANDARD USC AND GS BRONZE DISK STATION MARK WEDGED IN A DRILL HOLE IN THE SAME OUTCROPPING ROCK THAT THE ORIGINAL MARK IS SET IN.

  • The orthometric height was scaled from a topographic map.
  • The Laplace correction was computed from DEFLEC99 derived deflections.
  • The geoid height was determined by GEOID99.
