Found on St Patrick’s Day after visiting the St Louis Arch

One of many benchmarks spotted by our squad on our roadtrip this weekend from Indiana to Kansas and back.

couldn't get into the Arch today so we walked down by the river

Thanks to Geowoodstock XII that brought me here to enjoy the area!

Found this while visiting the St. Louis Arch. I love bridges, so this benchmark was a lot of fun to discover.

Logging some benchmarks after a long time on my list. Sorry for the late logging.

Never seen one like this before. Very cool :)

Found this one while driving through the area today with Jffok and Secondgunman, and Ashallond on our way home from GWX.

Snagged this one as we were leaving the Arch. This one has certainly seen better days, but it's still the most interesting marker I've come across.

Wonderful mark, unlike any I've seen before. I wish it were a little more accessible for close inspection.

Found this while attending the Big Muddy Blues Festival!

Could not get too close to this as the water was high. Picture was taken from a distance, so not much detail.

Found today with my wife before we went to the Home Show. Took a picture and several other pictures of the Lewis and Clark Statue.

Found while in town for the NATIONAL FLOOD RISK MANAGEMENT: LEVEE SAFETY SUMMIT.

Found today while doing some lunchtime caching with natesdeal and a colleague.

Team GeoBeagle
Keep your nose to the ground and your tail to the sky!

Located this one on the way home this evening. The pics do not do its size justice. It is a large plate in the side of the base of the bridge.

I found it on the 23rd as well. Still in good shape.

I seen it today too.

This one is easy to see from the new statue and benchmark.
This is the one I pointed out to Dave Doyle.
It is the one he said that this is the first time someone my age knew what a benchmark was.

What an honor.

Found as described. Handheld coordinates are approx. N38-37.748 W090-10.911.

This is the closest station to the Lewis and Clark commemorative disk monumented vertically in the south face of the base of the large, bronze statue "The Captains' Return". The L&C disk is about 41 feet south of the south-most point of the pier (in which JC0043 is mounted), and at handheld coordinates N38-37.740 W090-10.911. For additional info, see the waymark file at: http://www.waymarking.com/waymarks/WMR7H

Looking north, the station is two courses above the dog'd head. "The Captains' Return" in the foreground with the L&C commemorative in the base, just above notebook.

THIS IS THE CLOSEST BENCHMARK TO THE LEWIS AND CLARK STATUE AND THE NGS HARN SIGNATURE DISC.

SINCE THE COORDINATES ARE NOT PUBLISHED YET I WILL LIST MY GARMIN HANDHELD COORDINATES AND SOME PICTURES.

Found easily--especially with the pics posted here by others. Water seems to be rising. Will post a pic or two in a day or so showing the current water level.

Easy find walking around by the river.

The mark is on the left side of the picture, a bit above the middle.

Easy find once you look up...

Found with Charlie.

Got this one to see what the other might look like on the oppisite side of the bridge.

I returned today to one of my favorite benchmarks to get a quick reading of the lat. / lon. on the levee below the benchmark. I used a handheld recreational GPS (Magellan Meridian Gold).

Quick find while waiting for a table at the Old Spaghetti Factory. My boys threw rocks into the river.

Easy to see. Water is quite a bit higher now than when happycycler took his picture.
PS I forgot to add that my husband saw this one first. He was quite excited.

A very easy find -- Eads Bridge is well known and the bronze plate is obvious from the South. Found in good condition. Photos of the plate were taken from the cobblestone beach below.

The lower deck of Eads bridge now carries Metrolink trains across the Mississippi. The top deck is being repaired for automobile use along with with a bicycle / pedestrian path. The following links provide some background on the bridge.

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.
