found under blacktop with metal detector it's just covered over went in twenty foot radius to make sure it's the only metal hit in the area were the benchmark is so it has to be it

As mentioned in a couple other logs, I wasn't able to locate the station. If the disk you found has an arrow on it (like the one in my picture) it is a reference disk, and you didn't find this benchmark.

That was brother-in-law getting the tri-state cash decided to grab this monument while grabbing a monument we thought we saw a manatee but it was actually diver without any buoys out diving by himself without any safety gear in the middle of the river next to the bridge abutments thanks

Found in the parking area on the other side of the guard rail under the bridge. Will add a photo soon.

Found It

There's no sign of this one. I think it must be under the handicap parking area and I see some others saying the same. There's now a very nice paved parking area with a wheelchair lane running the length of the one-way road around Laurel Grove, which is part of the Heritage Trail. The upgrade may have buried the marker. I grew up in the area and remember there being a dirt parking area in the past.

Think it's gone as well

As others have said, you can find the reference marks but they clearly point to the middle of the parking area. I'm not sure if this benchmark was removed or paved over.

Found while at the Tri state monument.

I do not feel that I can log this as a find and do agree with others that the Laurel triangulation disk has been paved over. Do to the large amount of snow in the area I also did not get a chance to see the reference mark #1 nearby.

Discovered with Jersey Pirated, Dollar bell and Piper

As reported in the 2005 recovery note, the benchmark itself is no longer visible. However, I did recover RM 1 and RM 2.

Note, the nearby Witness Monument, the tall granite pillar, dated 1882, is a witness for two boundary points.

One side of the monument describes the location of the Tri-State Rock, which is located near the water, at the confluence of the Delaware and Neversink Rivers. This marks the northwest end of the New Jersey - New York boundary. It also marks the northern end of the New Jersey - Pennsylvania boundary. Hence, the three states. The Tri-State Rock also has benchmark LY2604 set in the top center. LY2604 also serves as LY2611 RM 2.

The other side of the monument describes the location of the corner point of the New York - Pennsylvania boundary. This is located 475 feet due west from the Tri-State Rock in the center of the Delaware River.

found this while geocaching in the area. jumped at the chance to log this too!

As mentioned in a few earlier logs, the main station appears to have been paved over. Reference Marks 1 & 2 are still intact - and by following the direction of the arrows, you can get a general idea of the point in the parking lot where the main station would be..

This is the RM that everyone is finding. I suspect the BM is under pavement or water.

This entry was edited by agility3d on Sunday, 22 August 2010 at 19:20:02.

I found whatever it is...there seems to be quite a bit of discussion as to where - or if it even exists anymore - the actual BM or RM is located.

I was in the area for a TriState Event , wanted to do the nearby cache and since I didn't have a benchmark to my credit I thought these two here would be a great way to start. I'll be looking for more in my travels.

Found it while going to tristates cash

Wow! Very cool spot! Enjoyed the visit!

Great view of the river tucked right under the freeway overpass. I definitely recommend visiting it!

While we were in the area answering questions for a virtual cache, another cacher pointed this gem out.

As a few of the previous loggers have noted, this mark is likely under the paved parking lot or destroyed. The TRI STATES (LY2604) mark, RM No. 1 (stamped "LAUREL NO 1 1942) and the granite boundary/witness monument are not LY2611 LAUREL.

Stopped for this one on our way back from Maine. I have wanted to stop for this one for awhile now and finely got the chance.

Found With Captainmath and FoofyRacoon

As others have said, these coordinates seem to be in the middle of the parking area. The monument down by the water IS NOT this benchmark.

Major_Dad and Clan hitting some more caches on our way home stopped by to hit a 3-state Benchmark too! Well, the 'round' stone with trangulation disk doesn't seem to still reside here, but the 'reference' border marker will have to do for this one. We also went down to the other marker still remaining 'marker' at the water's edge!

Found while doing the Tri-State cache

Since most people are logging the reference point as a find, I'll join the club. The actual location seems to be paved over.

Found this while looking for nearby cache. Everything looks good.

Found the two benchmarks, but did not find the cache. BU1

To answer eaglespirit0, some Reference Marks also are benchmarks. Laurel RM2 is also LY2604 Tri States 1942. Laurel LY2611 has not been found since 1991. It is beneath the parking lot. It is probably still there, but is not accessible. RM1, of which many people have take pictures, is not LY2611 Laurel. It is one of the reference marks for LY2611, not the triangulation disk itself. Read the note by seventhings.
Another thing to be considered here is that LY2604 is not at the actual Tri-state Point. The actual point where New York, New Jersey and Pennsylvania meet is in the middle of the Delaware River.

DNF

Found while doing the Tri-State cache.

In answer to Eaglespirit-- a benchmark is a benchmark when used for surveying. It may be a metal disk or it may be an 'x' carved into a builing. Not all are noted on USGS maps. The metal disk here is most definately a benchmark. Nice bonus on Tri-state cache

I don't know a lot about Benchmarks, but benchmarks are not reference disks. As noted, it seems as if the actual benchmark is paved over. (Well, actually, it probably is paved over)

Thanks anyways! :)

Not found. The station's described location and adjusted coordinates are in a paved parking area. There is no triangulation station disk there. Found RM2 (see LY2604 which does double-duty as RM2 and TRI STATES 1942). Found RM1 65.6 feet north of the station's described location, along the northwest edge of the parking area and at handheld coordinates N41-21.456 W074-41.663. RM1 is about four feet west of the west edge of asphalt, about 42 feet north-northeast of the northeast end of a guardrail, and in a concrete monument that projects three inches.

This was a day of caching and benchmarking.

Note: The tri-state marker, RM #2.... is actually down at waters edge!
The state boundry marker / monument , has no surveyors medalion. The actuall bronze disc, see pix, is RM #1... is on ground just on other side of overhead bridge. Both have arrows pointing to the STATION mark..that seems to be "missing?"
Anyone used the arrows to acuratly define station location? in order to determin if it is in fact buried under road turn around?

Hey CGS, found it! Well at least reference marks LAUREL NO. 1 and LAUREL NO. 2 were found. Coordinates were pretty good. Used a compass bearing and pace measurement as an aid. Did a pretty thorough search for the triangulation station disk, but was unable to recover it. It may be under the blacktop of the parking lot?

P.S. R.M. 2 shows much more wear to the disk than R.M. 1

Took a while to locate the site, but once we drove the road toward the bridge it was easy to find.

[last edit: 11/4/2003 6:24:38 PM PST]

Only saw a fleeting glance of it, it was about to rain and the cemetary was closing!!

A quick find on the way to the Tri State Cache.

This triangulation station mostly likely is still viable, but the station mark itself appears to have been paved over. The historical descriptions leads reliably to the site. I can not log it as a find since I did not actually see the station mark and can not comfirm its existence. Reference mark #1 exists and is located roughly four feet northwest from the edge of the paved turn-around, and west-southwest of the southernmost end of the cemetery. The reference disk is in good condition, well exposed and the stamped designations are legible. Reference mark #2 is listed in the database separately as LY2604. ~Rich in NEPA~

[last edit: 8/10/2003 8:33:49 PM PST]

Until I see evidence to the contrary (and I hope I do!), I'm not convinced the [i]station[/i] mark has been found recently. Reference mark #1 does still exist, but to claim a find the triangulation station disk itself should be located.

Zhanna

Went to find tri-state benchmark a while ago and never saw this one. The mark is still there, my wife stumbled across this one while looking for a place to hide a cache.

[last edit: 6/11/2003 8:20:00 PM PST]

Unfortunately, the gravel parking area is now paved, and this benchmark was either removed or paved over. Should it be marked 'destroyed'?

Zhanna

LY2611 is located in a gravel parking area, immediately under the I-84 bridge over the Deleware River. It is in an 8x8 inch monument, and is now about flush with the surface. Hence, it was covered with gravel and debris and we had to dig it out and clear the ground cover. The 1991 description errs in describing the disc as a triangulation disk as it clearly has an arrow pointing to the Tri-State monument, LY2604. The disc is in good condition. . . . patrick & shirley
