Spotted this one while sightseeing and geocaching in New York. We have been here many times before and this time we found this unique benchmark.

in the area chasing caches and benchmarks all in good shape here

Lots of muggles looking at the nearly cleaned Cathedral. Easy find

Found in good condition as described. Interesting that the T on St. Patrick's is in the NGS database, but the almost pristine bolt from the same survey is not.

Found during my stay in NY...

Found these benchmarks while one my one day trip to NY from NC. All benchmarks found as described.

Came along here several times...

One of many benchmarks found today during our walk around Manhattan. Police officers standing guard nearby during Sunday morning services.

Found it but had to ask the cop who was standing in front of it if I could take a picture.

This was a little bit of a challenge. The paint shown in other pics has been washed away and as mentioned there is scaffolding in the way, but I found it..

The last of several BMs observed today. This one was hard to see as it is in dark corner of the facade of St. Patricks, and behind a metal support for some scaffolding. Lots of work going on on this Church. I got to go in and look at some of the shrines and chapels and stained glass inside. And also to enjoy the AC on such a hot day.

Found on a business trip to NYC. The general location is obscured by scaffolding but there's no problem getting close enough to see and photograph the mark. My first mark of this type ("T").

Easy to find this chiseled T with the description, but I couldn't get very close to the mark because of the scaffolding placed in front of the alcove. It really helped that the mark has been highlighted with yellow (chalk?).

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!!

The second T for today. It was a little bit hart to find because there were scaffoldings all around.

Found this one during my walk through New York City.

My son located it. There was work scaffording around the mark when we found it.

Found this while walking around the city before seeing a Broadway show.

Saw this one while walking around Midtown. Thanks for the earlier pic. It helped alot.

Found this with Devbrain after concert at Radio City Music Hall. My first Benchmark! thanks!

I had a hard time with this one. I looked around for about 15 minutes. I couldn't find 824.

Found it thanks to mr.magoo's pictures.

During our visit in New York I tried to find some of them an was successful at some places. This one at the nice cathedral.
Cheers from germany, avila99!

Found it after a thorough search of the surroundings.

Interesting, I was standing not 3' away from the benchmark just a few weeks ago when I was in town and watching the goings-on along 5th Ave.

Found after an organ recital at St Patricks. What a nice piece of NY history - a fabulous cathedral and a magnificent organ.

Found while traveling about NYC.

Found it while out for a walk on a beautiful march day. Unfortunately I missed the bolt that is set in the top steps not to far awy. I'll have to return for that one.

found after watching the skaters too... wow - what a trip to NY this has been for benchmarks and caches!

Found it during a walk at lunch.

Was in The city for the day and stopped by to check this unique one out.

Had to stop and check this out after watching the skaters across the way. This building is gorgeous!

Out caching with Trendy Magic. Late entering as never got this logged when he did and he's just now pointing that out to me. Thanks!

got it

I was in NY visiting from Jacksonville, FL, while my husband had to work. My hotel was just across the street from this one, so I was dead set on getting it. I search for it and followed Papa-Bear's instructions exactly (but was in a hurry to get to a play) and couldn't find it) went back at night with my husband and coundn't find it. We walk back one more time the day we were leaving and he saw it a split second before I did.

The T is on the fifth avenue side of the cathederal.

had to search a while until I spotted it ... wanted to go to the apple store opening but queues were too long so I decided to spend my time better ;-)

If you've come to find the "T", you should also check the other bench mark set on the Cathedral at the same time. It's a copper bolt stamped "B|M" set in the far left corner of the top step of the main entrance and it's not more than 8 or 10 steps from the "T". They were both set aoround 1910 by the New York City Board of Estimate and Apportionment and they are 2 of over 200 marks set in Manhattan (and of over 1000 marks set in the 5 boroughs) by a team headed by Frederick Koop. Of these, about 15 made it into the NGS database, but many of the others are still there waiting to be found.

The bolt is #824 (not in NGS database), and the "T" is #825.

The team often set marks in pairs as a backup strategy.

This view shows the bolt in relation to the left end of the top step.

This benchmark is difficult to see around dust...but I found it anyway thanks to the description and a few extra looks.

Facing the church entrance, it in the little niche between the first column to the right of the entrance and the 2nd (larger) column to the right (see photo). The chiseled 'T' is on the bottom granite base of the first column (left side of niche). It is very clear when you see it.

Do not be misled by shapes on the right side of the second column (further to the right) that might resemble a "T".

Found it on a business trip to the city. Took me a while to figure out. First chiseled mark!

6th benchmark we found while visiting NYC.

Right where the description said it would be.

My second benchmark while visiting NY from California and my first chiseled T. Such a simle mark but so important. Easy to find. I plan to visit many benchmarks while here.

Found as described. This is only my second "chiseled" bench mark I've ever found, the other was KU1458 found earlier today. Description is adequate, with the exception of the typo in the name "Patrick".

Being as inconspicuous as possible, I crawled behind the fake Christmas tree in front of Saint Patricks, to observe the station.

Chiseled 'T' at Saint Patrick's Cathedral.

This one is very similar to the one at the New York Public Library (KU1448), but it's a bit harder to see, since it's chiseled into rough rather than smooth stone. And, of course, it's St. Patrick's Cathedral, not "Partick's," as the official data sheet has it :-) Erin go bragh!

Documented History (by the NGS)

Unknown by NYBE+A (MONUMENTED)
1/1/1952 by NGS (GOOD)
DESCRIBED BY NATIONAL GEODETIC SURVEY 1952 AT NEW YORK. AT NEW YORK, IN BOROUGH OF MANHATTAN, ON SOUTHEAST SIDE OF 5TH AVENUE BETWEEN EAST 50TH AND EAST 51ST STREETS, THE HORIZONTAL BAR OF A CHISELED T IN THE VERTICAL SOUTHWEST FACE OF FIRST PILLAR SOUTHWEST OF MAIN ENTRANCE TO ST. PARTICKS CATHEDRAL, ABOUT 18 FEET SOUTHWEST OF CENTER OF MAIN ENTRANCE TO CATHEDRAL, 2.2 FEET SOUTHEAST OF WEST CORNER OF PILLAR AND 2.2 FEET ABOVE LEVEL OF WIDE STEP.

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.
