Many thanks to Golfin Fool for the excellent recovery of the station and reference marks. I was able to find all 4 readily since they had already been uncovered. I concur with the south being used as the azimuth; either that, or the directions are as if you are sighting the main station from the reference mark (but they don't sound that way). I made a similar recovery at Wataquadoc in Bolton. Also, I believe they are true north/south vs magnetic, so you have to add 15 degrees to your compass bearing. I dial in the direction, add 15 degrees, then turn the compass around backwards. Once I paced off, I was able to find the depression for the reference mark. The concrete cylinders holding these were installed very well. I went on to find the magic cache. I hope to have pictures to follow.

I returned today armed with a metal detector and a 100' tape. After trying the degrees on the data sheet for the 3 reference markers to no avail, I decided to try 180 degrees opposite them and BINGO. As the reference markers were established 72 years ago, at that time they were referenced from the South rather than the North. They were covered with several inches of composted leaves from the past seven decades.

Had a nice walk on the day after Thanksgiving with my son and grandson. We found the station, but gave up on the RMs after a brief search. Since my son lives only a few miles away, we decided to come back another day with a tape measure and perhaps a metal detector and track down the 3 RMs.

We also found the nearby cache and the corner stone where the SE corner of Natick meets Dover. Interestingly, the "N" on the Natick side appears to have been chiseled backwards so it looks a bit like the right hand half of an "M". Unfortunately my camera battery ran out after I got a picture of the "D" (for Dover) side so there's no picture of the backwards "N" to show you skeptics.

Found this benchmark disk in good condition while in the process of hiding a geocache nearby. We tried looking for the three reference markers but to no avail.

Found it, in good condition, near the coordinates listed.

This is quite a find. It was such a long time since the last observance, that I felt that it would be a pretty long shot, especially since much would be changed.

New description:
The station is a disk mounted in a flat, square monument, nearly flush with the ground near the summit of Pegan Hill, within the Pegan Hill Reservation, owned by the Trustees of Reservations. To reach the station, from the South Natick dam on the Charles River, go south on Pleasant Street, then take a right at the fork intersection with Pegan Lane. Travel on Pegan Lane to the parking lot at left. From there, walk south on a wide path to the summit to an Oak tree that is three feet in diameter - a clearing is visible behind it. From the tree, turn around and walk back north 25 feet. Turn left and walk westerly for about 65 feet to the station.

I found the station uncovered, which may indicate it has been visited before. I was unable to locate any of the reference marks, however. The leaves, old tree trunks, and loamy ground make it hard to discern shapes that could be the monuments the reference marks were on.

After that, I continued south to the south entrance where the path meets with the southern segment of Pegan Lane (no parking spaces). I took a side trip and found the southern cornerstone of Natick with Dover, as well as two fenced off cisterns. And, on the way back I tried to walk along Pegan Lane, which is marked as 'Not a Through Way.' I was forced back into the woods at a point where there was a clump of houses. When I caught up with the road again, it was at a point that was dilapidated and impassible. Near the parking lot, I came back to the maintained portion.

Control Text

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