Found a couple of these doing the long trail at the Palisades. Great views!

Found with macguyeric while hiking in the palisades. Great view from up here.

I spent a sunny (but cold) Saturday hiking along the Palisades from Greenbrook Sanctuary to the NY-NJ state line. I worked my way through 6 triangualtion stations and found almost everything I was looking for. I spent almost half of my time at [url=http://www.geocaching.com/mark/details.aspx?PID=ku4051]KU4051 "HIGH POINT"[/url] and managed to find 4 of 5 reference marks plus a witness mark, but alas, not the ststion mark. Still all-in-all a very productive day.

This station, like all of them today was on the cliff edge. After a while I got used to it and thought nothing of standing a few feet from a sheer drop of hundreds of feet. But the views were great. Oh yeah, try to be careful .

Unlike Harry Dolphin and crew, I came to this mark from the south. So I didn't see the old cellar hole till I left the station, but there was no problem finding the station or reference marks at all. Just go to the cliff edge and look on the rocky cliff points, and you'll easily find the station and two reference marks (of course it helps to use the datasheet).

I looked for the azimuth mark on the way from the south, but had no luck. I found no remnants of a sidewalk near the cliff. I may come back sometime to look further. But I did see a surprise. Somewhere between the missing azimuth mark and the station, I came up to a Peregrin Falcon perched in a tree. He flew off with a screech at my approach, but not till after I got a shot at him (with my camera - after all, it is endangered).

The cellar hole of Miss Miles' house which you will pass if you approach from the north. I found it on the way out.

A Peregrin Falcon, a special treat, perched in a tree south of KU4055. After I took the photo, he took off screaching and flew a few circles around me before dissapearing.

Found with Harry Dolphin and Andy Bear.

Found it.®

Following 1975 directions, this was easy to find. 85 paces south of ruins of old house.
Hand-held GPS coordinates for RM1: N 4 56.620 W 73 55.258. For RM2: N 40 56.624 W 73 55.257. Azimuth marker not searched for.
NJGS must have been having a very bad day in 1992.

  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in September 1999.
  • 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.
