Found in good condition as described. The road along the Cross Island Parkway, by the tennis courts, is now called Waters Edge Drive. The red building is about 50 feet off the southbound side of the roadway, and about even with the northern face of the southernmost of the three large apartment buildings. The marker is waist high at the right edge of the side of the building facing the parkway.

Yesterday I spent a long day in Queens, NY. I walked the "341" level line, surveyed in 1952 from "A 341" in Bayside to "K 341" at the Whitestone Expressway, with a side trip around Fort Totten and a little extra jaunt in Flushing. It was about 12 miles on foot and I was exhausted by the end. But I found 8 marks out of 14 (with about 8 others I couldn't get to) which is pretty good.

This mark was found in good condition as described. But like many of the marks I logged today, it had a heavy coat of paint, although the stamping can just barely be made out.

To get to this mark I first thought I would go up through the neighborhood on the southwest side of the parkway after I had recovered KU1123, "C 341".

I soon gave that idea up and went back to the bay side. This turned out to be a good idea, since I never would have found the little brick building without first having seen it from across the parkway. It was right on the side of the parkway in front of the first of three huge condo towers.

As it is, after I saw the building from the bay side, I went all the way up to Fort Totten,went under the parkway on Bell Boulevard, and then followed the street that went southeast next to the parkway.

When I got to the tennis courts and the huge condo towers, I found a convenient hole in the fence, went around the tennis courts and over to the parkway and got to the little brick building without problem. This added about a mile, due to the backtracking involved, but aside from the certain suicide of running across the parkway, there was no alternative.

Control Text

  • The horizontal coordinates were scaled from a topographic map and have an estimated accuracy of +/- 6 seconds.
  • The orthometric height was determined by differential leveling and adjusted by the National Geodetic Survey in June 1991.
  • The geoid height was determined by GEOID99.
  • The dynamic height is computed by dividing the NAVD 88 geopotential number by the normal gravity value computed on the Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45 degrees latitude (g = 980.6199 gals.).
  • The modeled gravity was interpolated from observed gravity values.
