sometimes gps signals in a big city are imprecise, so we walked once around the block

Jashdo almost walked over it and then we search around the block and again.... the pictures helped to spot it under all the paint.

Found in good condition as described. I remember seeing this mark about 40 years ago, when it was not painted.

Found with the aid of the pictures post here. Shame that it is painted over.

Located this one while working on the nearby 9-11 puzzle cache. The information from previous finders made this an easy one to track down even with most of it being covered in paint!

Found it during a caching tour in NYC... hard to find this NGS benchmark...

Really hard to find, but actually still there.

Found as described. Paint is chipped away enough that you can recognize the disk for what it is.

My second BM ever

Eine interessante Variante von Geocaching, die ich so bisher noch nicht kannte. Und wenn man schon mal über den großen Teich gereist ist, muss man dies natürlich auch mal testen! Der Benchmark befindet sich wie angegeben in gutem Zustand am bekannten Ort!! Vielen Dank fürs Zeigen!!

This was my first Benchmark, I could find it during my business trip to New York, thank you :-)

Found this benchmark as we were walking around the WTC area on July 4th. The benchmark is there if you look hard enough.

Quick find after grabbing the first stage of the nearby multi.

Found while spending the day in the city.

We found this benchmark while walking around Ground Zero.

Found this one during my walk through New York City.

Spotted this benchmark this morning. Been walking past it the past few weeks since the new temporary PATH station opened up.

Took a quick detour from my morning route to find this one.

Found it painted by thick Yellow paint. Also found nearby "B B"

photo KV0592 Q 340

Found as described.

As others have indicated, the paint prevents a clear reading of the disk. but the words "MARK" and "LEVEL" and other pieces of words are visible and possibly the "Q" and "4" of the designation. The layout of the visible printing indicates it is a USC&GS bench mark disk.

If you look carefully you can see pieces of text: "BEN.H", "MARK", "FEET", "LE.EL", "S..VEY" and in the center, the benchmark cross and above that "Q ..4".

This was our final NGS mark for the day. As the previous finder mentioned, the entire door sill has been painted over with a thick layer of yellow paint, and as a result the mark was difficult to spot even though the directions were explicit. I walked past it twice before noticing the vague “lump” on the Parcel Post door sill. Currently the mark is easily accessible from the sidewalk; though there is still construction in the area, the doorway is no longer covered by plywood as is mentioned in the January 2004 NGS recovery note. I was unable to get a GPS reading of any kind in this area.

Like “Trippers,” we then explored the area a bit and found many more marks nearby. Because of the current reconstruction and restoration of this downtown area, it seems nearly every corner holds some sort of survey mark—either a cross chiseled in the sidewalk, or a survey disk.

We found and documented the following disks:

We also found BB, but we couldn't photograph it because at the moment it was located directly beneath the feet of a Chinese woman working at a souvenir stand!

[i]A report on the condition of this mark has been submitted to NGS, along with the following recovery note:[/i]

Recovered in good condition. Door sill and mark have been covered with yellow paint. The doorway is no longer covered and the mark can be accessed easily from the sidewalk.

This part of downtown NYC is subject to a good deal of post-9-11 rebuilding and this benchmark is just a block north of the world trade center site.
This benchmark is located at the foot of the post office door just in the middle of the block. The benchmark is clearly visible but the lettering is obscured by at least one thick coat of bright yellow paint. I could not make out the id under the paint, but could make out enough of the lettering to be sure it is a NGS benchmark, and its location does match the description.

More interesting were the unexpected benchmarks that seem to have sprung up on so many of the sidewalks in the area. I found four of these on my walk between kv0592 and the commuter ferryboat dock. These new benchmarks are all round, flush with the sidewalk, have a triangle with dot in the middle, and bear the inscription "THE PORT AUTHORITY OF NY AND NJ DOWNTOWN RESTORATION PROGRAM." They do not record elevation. Each one has a 2-5 character id in capital letters. Here are the four I found and the handheld GPS readings. Distances are approximate.

"BB" - 5 ft SE of SE corner of Barclay and West Broadway (near to kv0592) Weak reading on my handheld GPS due to urban canyon setting: W74°01.033', W74°01.033'

"WEB" - 5 ft NE of NE corner of Barclay and West Streets. Weak reading: N40°42.838', W74°00.862'

"WEV" - 15 ft NE of NE corner of Vesey and West Streets. No reading possible due to scaffolding

"NORTH" - W of W end of Vesey Street, 40 ft E of railing on sea wall. Strong reading: N40°42.907',W74°01.033'

It occurs to me now that the id is closely related to names of cross streets. I think I'll have some fun and try to hunt up more of these new benchmarks. Must get a small, digital camera.

With the associated work at WTC, the location is behind a construction fence.

Documented History (by the NGS)

DESCRIBED BY COAST AND GEODETIC SURVEY 1952 IN NEW YORK. IN NEW YORK, IN BOROUGH OF MANHATTAN, AT THE INTERSECTION OF WEST BROADWAY AND BARCLAY STREET, 22 1/2 FEET SOUTHEAST OF SOUTHEAST CURB OF WEST BROADWAY, 125 FEET SOUTHWEST OF SOUTHWEST CURB OF BARCLAY STREET, SET IN THE TOP OF THE SOUTHWEST END OF THE GRANITE DOOR SILL OF PARCEL POST ENTRANCE TO POST OFFICE AND FEDERAL BUILDING (ADDRESS OF BUILDING IS 90 CHURCH STREET) AND ABOUT LEVEL WITH SIDE WALK.

RECOVERY NOTE BY NATIONAL GEODETIC SURVEY 1974 RECOVERED IN GOOD CONDITION.

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. WARNING-Repeat measurements at this control monument indicate possible vertical movement.
  • 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.
