Found the drill hole as described in the top of a large granite boulder at the summit of Tiffany Mtn. It is about 9' NNE from TP1195. The hike is 2.1 miles from NFS Rd 39 at Freezeout Pass on maintained trail. The summit runs a ridge in both directions from the true summit. Views are expansive in all directions, from Silver Star Mtn to Canada to the flatlands of Eastern WA.

What a view from here, was able to see Mt. Baker to the West and the beginning of a fire near the Omak/Tonasket area to the East.

What a view from here. I'm curious what the nearby lookout must have looked like. This would have been a wonderful view of the Thirty-Mile Fire last year.

Found the drill hole; no evidence of a cairn (or of the lookout mentioned in the description for nearby TP1195). Approached using Chewuch Road, FS37 and FS39, then hiked up via Freezeout Ridge trail and Tiffany Summit trail.

Control Text

  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in December 1991.
  • 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.
