Must Read!

I am very thankful for the thrill of hunting for benchmarks that I began at the start of the pandemic in 2020. It was a safe, outdoor activity and I gained much enjoyment from this new pastime that complemented geocaching so well.

I am very disappointed that will no longer support benchmarking because not enough people do it. I love it and will be very sad to see it gone. All of these logs and pictures and coordinates that were added to these pages by geocachers who love this aspect of the game are about to be dumped in the trash heap forever. I realize that no one is going to see this complaint but I'm making it anyway.

Such a cool spot! Found while visiting the Mile Zero cache.

Discovered this benchmark while searching for GC2E52, Mile Zero.


Now touring around on scooters after a thunderstorm soaked the town and us. The mark is in fine shape despite the big wall blocking the view of the White House.

The view of Zero Mile looking north towards The White House. That is Kellann that the mark is holding up.

Found while out for a bike ride around downtown today. I've been here a number of times, but I'm finally logging this benchmark!


well if this isn't the benchmark of benchmarks! a super find here!

Easy find of course

New York's worth a trip. Together with 12 cachers we visited this metropolis. Because we don't write the logbooks all the same, we logged under the name "Going New York 2019". From the party were AdyausDu, Brummelbären, Fotopinguin, gifmik-team, Kleinzschachwitzer, Matzi76, Oberi and we (2Berkas).
I write a mass log, but a long one.

Day 1.
Just landed and put the suitcases in the hotel we went to the Times-Squaere. Wow quite crowded here. Af-terwards we walked to the Empire and drove up. King Kong was not there, but we got a great view over New York at night.

Day two.
Off to Staten Island. The weather was not on our side. Brrr the XXX was cold.
Afterwards we headed towards Broadway and finally we went to Ground Zero,

Day three.
Off to Old Caches. Peter meant to give us a very small foretaste of the winter at the east coast. That's how I like winters. Although we unfortunately did not manage to do all that we had planned to do.

Day four.
Off to Washington DC. Washington and NY cannot be compared. But we enjoyed the trip to the capital very much.

Day Five.
A little shopping and then sightseeing (again ground zero. Flatiron building. Rockefaller Center

Day six.
One ferry from downtown to uptown, Central Park please.

day seven
Shortly before the departure still various objects of interest visited.

The answers to the Earthcaches have already been sent by the photopenguin.

It remains to say that the week flew by. Thank you for showing us every single place. Who knows if I would ever have come here without geocaching.
But the thing is, I can't sing anymore.

I've never been to New York, I've never been to Hawaii
Never walked around San Francisco in ripped jeans
I've never been to New York, I've never really been free
To be crazy once and escape from all constraints
(I have never been to new york - udo jürgens)



New York ist eine Reise wert. Zusammen mit insgesamt 12 Cachern haben wir diese Metropole besucht. Da-mit wir die Logbücher nicht alle gleich voll schreiben haben wir unter dem Namen „Going New York 2019“ geloggt. Mit von der Party waren AdyausDu, Brummelbären, Fotopinguin, gifmik-team, Kleinzschachwitzer, Matzi76, Oberi und wir (2Berkas).
Ich schreibe einen Massenlog, dafür aber einen langen.

Tag 1.
Gerade gelandet und die Koffer im Hotel habgestellt ging es zum Times-Squaere. Wow ganz schön voll hier. Danach sind wir zum Empire gelaufen und Raufgefahren. King Kong war leider nicht da, aber dafür beka-men wir einen super Ausblick über New York bei Nacht.

Tag 2.
Ab nach Staten Island. Das Wetter war nicht auf unserer Seite. Brrr war das XXX kalt.
Danach ging noch Richtung Broadway zu Guter Letzt ging es noch zu Ground Zero,

Tag 3.
Ab zu den Alten Caches. Petrus meinte uns einen ganz kleinen Vorgeschmack auf den Winter an der Ostküs-te zu geben. So lass ich mir den Winter gefallen. Obwohl wir leider nicht alles das geschafft haben war wir vorhatten.

Tag 4.
Ab nach Washington DC. Washington und NY kann man nicht miteinander vergleichen. Aber Der Ausflug in die Hauptstadt hat uns gut gefallen.

Tag 5.
Ein bisschen Shoppen und danach weiter Sightseeing (noch mal Ground Zero. Flatiron Buildung. Rockefaller Center

Tag 6.
Einmal Fähre von Dowtown nach Uptown., Centralpark bitte.

Tag 7
Kurz vor der Abreise noch diverse Sehenswürdigkeiten besucht.

Die Antworten zu den Earthcaches hat schon der fotopinguin geschickt.

Bleibt zu sagen die Woche verging wie im Fluge. Danke für das Zeigen jedes einzelnen Ortes. Ob ich jemals ohne geocaching hierhergekommen wäre, wer weiß.
Allerding kann ich jetzt nich mehr singen

Ich war noch niemals in New York, ich war noch niemals auf Hawaii
Ging nie durch San Francisco in zerrissenen Jeans
Ich war noch niemals in New York, ich war noch niemals richtig frei
Einmal verrückt sein und aus allen Zwängen fliehen
(ich war noch niemals in new york - udo jürgens)

Of course, we also wanted this one GeoCache / Benchmark on the To-Do list to pick up. And now there is a smiling face. There were no problems ... Yes, the destination fits. Thus: the end is good, all right ...

In other words:
Everything is there, where it belongs, undamaged and waiting for the next visitors.

Now we like to say:
Thank you for your GeoCache / Benchmark and another smiley on our map.

I was here for the geocache "Mile Zero" and found this benchmark too.

Turns out, this benchmark is also a geocache! So the mark is bronze. Thought it would be more orange.

The mother of all benchmarks ;-)
Found it at 23:30, not many people arround at this time ..

All is good with this one.

Found this bench mark while completing 15+ virtuals in DC. It was a mad house around the marker with people trying to get pictures of the White House (since they blocked the road) but ignoring the marker.


We found this benchmark during a round trip through this part of the US. We were lured to many great places and discovered some extraordinary places that would have been hidden from us without geocaching. Many thanks to all the owners and greetings from Southern Lower Saxony in Germany.


Out for a morning walk before my conference starts for the day. Miraculously, the rain held off for the entire hour I was out. I came here for the Mile Zero virtual cache, and figured that the location likely was also a benchmark. Two "finds" for the price of one! One of these days, I need to spend a few hours finding other benchmarks around the area.

The mark/monument is in good condition.

Day 1 of a 9 day wild road trip with ksumom2004. We attempted to squeeze as much of Washington DC into one day as we could and we could barely walk by the end of the day (approx 30,500 steps / 12.75 miles), but what an amazing day. Seeing all the different monuments and statues and other wonderful places geocaches took us was well worth the pain. Saw this one while doing the Mile Zero geocache at the benchmark.

Recovered as described. Description and coordinates are both spot on.

Came down to DC as my own kind of pre-holiday vacation before the chaos starts at Thanksgiving. The weather is lovely if a bit chilly. At least there’s no 8 feet of snow like upstate NY is getting. Spending three days caching around the District and across the river in Virginia. Have plotted out approximately 75 caches to go after on this trip. We’ll see how well I do by the time it’s all over.

This was among the first things I found in DC. Very cool!

Found while caching in the area. This has to be the mother of all benchmarks.

Need a walk so I came over here during lunch. There were many Japanese tourists, all taking each others pictures, so I waited patiently. Eventually got to where there was one woman standing on the plaque and I gently gestured to her that I was trying to get closer so I could touch it. She moved, I touched it, then said "Thank you" in Japanese. The rest of the group heard me and commenced to speak to me in Japanese. I had to get the tour guide and explain that at best I knew half a dozen words of Japanese. After much mutual bowing, we parted.

Definitely a fun mark. I had never seen one like it before.

Spent the day in Washington DC, riding around on my bike, going mostly after virtual geocaches. In my travels, also going after traditional geocaches and some bench marks.

photoIn the area

Did a lot of bike riding all around DC today to get as many geocaches as possible. In my travels, I made a stop here, only because there was a virtual cache here. If there wasn't a virtual cache, I never would have known about this one.

photoThe view from the marker

We found our first benchmark just some days ago in Maine.
Then a geocache led us to this place and I remebered the circumstances: this one should be found too!
We didn't have to search a lot, but we are proud and happy to find the ZERO MILESTONE, were the story began...

Very nice benchmark.

Picked up the virtual, the waymark and the benchmark all at the same time . -40-


[navy] Visited during my trip in Washington DC.

:grin: :grin: :grin: :grin: :grin:

This one is a virtual cache and googled to check if it was a benchmark and it was :) Awesome benchmark.

Stopped here for the Virtual, and looked up this BM. We enjoyed our visit here. All is well.

Found this one while here for the virtual cache and the waymark as well. Love these 3 for 1's! :D

I was in Baltimore all week with a group of youth on a missions trip from College Station, TX. After our week of work, we took a day to visit our nation's capitol. Trying to stop to get info while the rest of the non-caching group just wanted to keep moving was difficult at best. It was rather warm and humid today. It's pretty cool to be standing in the same exact spot as so many great people in our history have stood.

found it ...

Another find in D.C.

Got the virtual cache here. Milestone is in good shape (obviously) :)


Found this while in DC recently on a virtual caching tour

Found it while I was on a business trip in D.C.

photoWashington D.C. first milestone

Nice view of the White House from this marker.

Found it while doing the virtual cache a this location.

Found while doing Virtual Mile Zero. I too wish I know more about locating benchmarks. Hopefully, one day I will.

Well the zero mile virtual is in this location, so I found it without problems…Missed most of the benchmarks while in D.C, have to learn more about them.

Found this with bearcap12 in front of the white house

I am here in the United States of America now for two months and on my to-do-list was also a trip to Washington D.C.. Driving from Pittsburgh I planed a scienic route through a lot of nice places and alltogether four states - and D.C.. I saw the Appalachian Mountains, the lights of the cities and all the places I only knew from films and television till now. Three days is not very much time for such a plan but it was all we had. It was a tough tour, but worth the effort. This is my first NGS Benchmark and I am looking foreward to find some more while I am here in the states. Greetings from Germany.

Was brought here by the virtual geocache, and we figured there HAD to be a benchmark here! YAY!!!!

Found this with hokiecachers and sazames today. I love zero mile markers. This is my third, including Madrid, Spain and London, United Kingdom. Thanks for the smiley!

Got the virtual that went with this. Had to log this too!

This was one that you just couldnt miss while out hiking the area and stopping at all the Virtual Caches in the area.

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!!

thanks ..


This definitely ranks as one of the greatest benchmarks ever.

Visiting my brother in DC

Spent the day in DC. This is a easy marker to find.

Found it while on vacation. So many people taking pictures of the White House, but nobody except me took pictures of this historical benchmark.

Grabbed this one at the same time as the Geocache with the same name!! Great place and a great view!!

Now there's a benchmark! Saw members of the first family playing with the dog on the south lawn.

Found with Iguk! and GeoNewt. Very interesting location and a very cool thing to log as my very first benchmark fin.

On a family tour of DC, I managed to find this cool benchmark while the rest of the family took photos of the White House. Love the visual fanfare!

Very cool indeed

What a very interesting item.

I spent my holidays in the United States. I took the opportunity to visit Washington, wonderful city full of magnificent monuments and sculptures. I went looking for geocaches, waymarks and benchmarks. Thanks for this one.

The marker sits right in front of the White House. It was a special treat to see all the beautiful lights on the National Christmas tree and the extra decorations on the White House.

Cool Benchmark!!!

I found this whilst doing the Zero Milestone Geocache

Found on our trip to DC.

Did some exploring and caching while the rest of the family was busy with other things today. What a great area.

Stood right next to this today and realized it was probably a benchmark. Turns out it is.

This was one of the benchmarks I really wanted to get up close to...but the Police had blocked off access....hopefully it will be available again tomorrow.

Next Day...after the helicopter left the White House we were able to get right up to it.

Found while visiting the area.

Found during our hollidays in the D.C.

Found while in the area working. Thought it would be fun to buy a bike and do some caching..saw this and knew hade to be a benchmark so I looked it up and here it is.

Spotted this likely loggable benchmark while in the area for a business trip. Checked online a couple days later to verify it was a loggable one. Since I'm not caching outside Michigan this year, I didn't log the virtual cache here (or any of the others I visited). Benchmark itself is in good condition.

photoZero Milestone
Spotted this benchmark as we were waiting for the President's helicopter to depart.

Found after the "Restoring Honor" rally. Cool benchmark and it's in good shape. This is a popular spot with tourists.

I almost forgot to log this one.

Spotted today after a fantastic Restoring Honor rally on the mall.

Found this benchmark still standing and in good condition while Geocaching in the area.

This is one of the coolest benchmarks I've ever found. Found amid the huge crowds today.

A 2 for 1 deal seeing this is also a virtual, love it. My first logged benchmark.

Love it when a cache is right at a benchmark.

Nice to get a benchmark amidst the virtuals. I'm pretty sure we snapped a pic but I can't put my hands on it at the moment.

The National Christmas Tree and a view of the White House brought us to this spot, so this benchmark was a bonus.

I came to the marker for the virtual cache, but when I saw it, I thought "I'll bet that is a benchmark!" so I took a photo of the compass rose on top. Looks like I guessed right.


Found it while geocaching in DC. I guess this one is a must for everybody who is interested in benchmarks.

Found this while getting the associated Virtual Cache

Been here before - grab it as I ran by today.

Found this while the wife went out for a run.

Recovered as described, in good condition, while visiting the virtual cache set here. Not sure why this mark is described as having "questionable or unknown stability" -- seems as permanent as any other concrete or stone monument I've seen.

Recovered in good condition.

Visited this benchmark while walking along The Mall.

Hard to miss once this one when you are right there in the area.

This is the first benchmark we found. Luckily it is hard to miss and still in very good shape!

Might as well grab my first benchmark as long as it is so obvious. :P Someday I will take up benchmarking, but for now I will be sticking to traditional caching.

Yup still there in excellent shape :)

photoMile Zero Washington D.C.

We're on a ten-day vacation to D.C, and saw this while on a walkabout of the areas near The Ellipse and the Federal Triangle. This has to be one of geocaching's most-logged benchmarks; not only have nearly 200 logs been filed here, but two geocachers have filed Recoveries with the NGS, the most-recent just four months ago. Thus, we have no reason to file one of our own Some interesting inscriptions on the marker; lots of stuff we hadn't known until now.

Visited this during a visit to GC2E52 - Zero Mile and Waypoint WM635W - Zero Milestone. In town with some family to visit Barack Obama's House.

Found it while caching and taking in Washington DC on Independence Day!

We were in the center of everything and we knew it-nice!

I found this geocaching, but I figured it must be the mother of all benchmarks.

Found as a virtual geocache while on vacation in DC. It wasn't until after I got home I thought about it being a benchmark. Lots of fun came from that trip.

photoCompass on top

Could this be one of the most famous benchmarks...

I had logged the virtual cache here. Just found out that it's a benchmark. For some reason, all the muggles had their attention focused across the street. :-)


Found while on tour of DC. Wonderful day!!!

I didn't realize I was finding this. I was actually looking for the virtual cache that is attached. ;)

Found this as a cache, but later realized it was a benchmark too. Thanks

We don't have the facility to log our bechmarks (called Trig points) in the UK, so it's always nice to bag a couple while I'm in the states!

I tried to get this benchmark on the 15th but security around the White House was really tight and no one could get anywhere near. My thoughts were that the President was out running or walking the grounds of the White House so I had to wait until today to schedule a series of caches, banchmarks, and waypoints that included this one.

If I had known that this was also a benchmark I would have called it the same time as when I did the cache...Oh well I'll live I think. :)

I'll go ahead and call this one as found the same time I logged the location as a cache... cheating? nah...

Found this benchmark. Construction just south of it, but doesn't prevent you from going right up to it.

Forgot to write down numerals on east side, but it is touchable for the moment.

Found it.

At the time of my visit to the Zero milestone I had no idea it was a benchmark .

Found with virtual cache.

Sought the milestone after seeing it on a local map -- I actually wasn't intending to 'seek a benchmark' during my hunt. But, I figured it'd be on the website. So, now I shall log it.

Realized that this was a benchmark as well. Seeing the survey disk didn't click for me while doing the cache but realized it soon there after.

Out finding a few quick virtual caches today and came across this benchmark. Very interesting history of this one. Nice view of the White House as well.

I was in town for the day and I finished up my business around 5:00 PM. Made it here as well as some of the virtual caches in the area. My friend and I were asked twice where this benchmark was located, and we were asked to take pictures of the seekers standing next to the benchmark.

Found this as a virtual cache on a foggy night at week before the inauguration. Cool spot.

Found this one while doing the cache here. It's the biggest one that I've found so far.

Whenever I visit DC I am usually on the other side of the road and do not remember seeing this before.
Great photo spot as well.
Happy hunting,

Found on a caching run with Zinnware and Highgear

Sightseeing in DC, looking at monuments & seeing how many virtual caches & benchmarks we would come across. Found this while looking for the Zero Mile virtual.

This weekend cache run put 1,502 more miles on the geocaching vehicle. We only found around 44 caches, but we got to add a few more states to our list of cache finds! This benchmark was easy to spot while on our cache run.

This is perhaps my favorite benchmark find!

Here is a little history lesson for you! - Enjoy

The Washington zero meridian is established by Andrew Ellicott (1754-1820) in laying out the streets and lots of the City of Washington in the District of Columbia according to the plan of Pierre L'Enfant. The Washington prime meridian (0° 0') is drawn through the site of the proposed Capitol, 77° 00' 33".533 west of Greenwich, England. An east-west line, also passing through the Capitol, is established at the same time.
In 1804, a new Washington meridian is established through the center of the White House that extends north on contemporary 16th Street (source of the names for Meridian Hill and Meridian House, headquarters of the Association of American Geographers). The intersection of this second Washington meridian and Ellicott's east-west baseline is delineated with a stone marker. Although the original marker is subsequently altered, the Jefferson Pier, as it comes to be known, continues to delineate the site today. It serves as a Federal Base Network point (the geodetic control point with the highest level of accuracy in the District of Columbia) and is located 371 feet west and 123 feet north of the center of the Washington Monument. The location of this second Washington meridian is also delineated by The Zero Milestone located between the White House and the Washington Monument, which is established in the 1920s to serve as the point from which highway distances from Washington, D.C. are measured. It provides a contemporary rendering of the Itinerary Column originally proposed by Pierre L'Enfant to measure distances from the capital city to other portions of the continent.
The White House-centered meridian, along with a third one established in the 1840s at the Old Naval Observatory, serve as zero meridians for numerous American maps throughout the first half of the nineteenth century. Zero meridian lines are established for mapping purposes elsewhere in the United States-Boston, Philadelphia, New Orleans, and Charlestown, South Carolina among other locales. The United States Congress on September 28, 1850 officially adopts the Old Naval Observatory as the national meridian for astronomical purposes and well-known meridian at Greenwich, England for nautical purposes. (see International Prime Meridian Conference entry at 1884)

Found with Iontarget and TheStosh in D.C. while geocaching. This is the biggest benchmark that I have ever seen. It was in good shape, but the engraving was a little worn off. We had to leave here quickly because G.W. was leaving the whitehouse.

This was an easy find, excelent description, coordinates within 15 feet. It is located on the north side of the ellipse and just south of the White House security fencing. Thanks, Fort Rectus

The Zero Milestone was recovered as described, in good condition.

Found it while geocaching in D.C.

Visited from Annapolis just before the national Christmas tree was taken down. Great display and tight security, too.
Enjoyed checking out W's crib.

Tough to miss this one. Shortly after New Years Day in 1992 I proposed to my wife on this very spot. I'm still married and Zero is still here.

I ran into ( JoeCthulhu and the rest of ( The 2nd Annual Capital Cache Walk mob while here. Despite having different destinations after this, the whole mob of us ended up heading in the same direction for a while.

Found this by chance when looking for the "Mile Zero" virtual cache. I wasn't really looking for benchmarks but had my first sightseeing tour based on geocaching.

photoa busy spot

found with charlie. this is the day we got stopped by the secert service.

My Thanks to the SECRET SERVICE for their continued work on the protection and Safety of our National Monuments.
I am glad to see that you are watching.

Hey wow! It's still here!

Late log on this one. I was in DC a few months ago, and just for the heck of it thought of checking this out to see if it was a BM. Sure enough, it was. This is the first BM I don't have a pic of, but I suppose I'll live.

Found as described.

Looking North at the monument. Large, familiar-looking house in the background.

Found it as a Virtual Cache (

No particular challenge to this, but I was just a few blocks away seeing a photography show at the Art Museum of the Americas (, so why not....

Yep, you guessed it. I was virtual caching this spot and wondered if it was logged in as a bench mark. It is, so add my name to the list of finders.

Found this benchmark like everyone else while hitting the virtual cache here.

As with many others, I claim this along with the virtual cache of thes marker.

Found it along with the virtual cache.

Found this today in conjunction with a Virtual cache. First Benchmark logged for me.

Located just south of the White house, very easy to find.

9:20 pm.
Logging in conjunction with virtual find GC2E52. Had to vacate the area when bicycle patrol officers swept the area for the President's return from giving his State of the Union address.

Nice view of the Nations Christmas tree from here

Log added 11/17/2003 - We just got into GeoCaching and saw the BenchMark page as well - we logged the GPS of this benchmark when on a vacation last year in Washington, so took the liberty of dropping this comment in

This is daughter crew member on class trip to DC area.

Found with virtual cache also.

We are coming here for July 4th hopefully this year also as a family. Will follow up with picture hopefully when I get home.
We are from Hamilton, Ohio (near Cincinnati)

Control Text

  • The horizontal coordinates were established by GPS observations and adjusted by the National Geodetic Survey in June 1994.
  • The orthometric height was determined by differential leveling and adjusted by the National Geodetic Survey in May 1999. WARNING-Repeat measurements at this control monument indicate possible vertical movement.
  • The X, Y, and Z were computed from the position and the ellipsoidal ht.
  • The Laplace correction was computed from DEFLEC99 derived deflections.
  • The ellipsoidal height was determined by GPS observations and is referenced to NAD 83.
  • 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.
