I spent a productive 4 day weekend in Northern New Hampshire and Vermont in late September. From Friday noon till Monday noon. The weather on Friday and Monday was great, but Saturday and Sunday were rainy. But luckily we escaped the worst of the rain which came late in the day for both Saturday and Sunday.

The targets were all boundary monuments and related marks: Boundary Monuments, Reference Monuments and Triangulations stations used in the boundary survey done from 1914-1919. The Reference Monuments were not in the NGS database, so I include them as "extra credit" stations logged with the nearest NGS station.

On Saturday we worked our way up Indian Stream Road in Pittsburg. This station is a triangulation station, but unlike the 3 out of 3 of these which I found on Friday the 25th, this was one of the 3 subsequent DNFs that we logged on Saturday and Sunday. I guess as in baseball, some days you just have it and some days you just don't.

We took a logging road off of Indian Stream Road to get near this peak. The aerial views showed what looked like an old woods road that would get us near the top, but it petered out so we just whacked straight to the summit. We first checked out the actual high point and signed onto the hikers register there. Then we headed back down to the area of the mark, about 250 feet north of the high point. The description gave very little to go on: "STATION MARK--STANDARD BRONZE DISK SET IN ROCK". Just "ROCK", not "A ROCK" or "ROCK OUTCROP". So we searched the area - which has plenty of rocks - with probes and the metal detector and scraped off a number of the promising rocks, but to no avail. After about 30 - 45 minutes we gave up and headed back to the car.

The photos show several likely spots.

Control Text

  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in May 1998.
  • 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.
