My eldest son, Jeff, and I walked the trail at Jones Point, a geographic point on the Potomac River which is part of the city of Alexandria. A small park and the Jones Point lighthouse are located at the point, which is immediately North of the confluence of Hunting Creek and the Potomac river. The 1791-1792 survey of the boundaries of the District of Columbia began at a spot that was then at the tip of a cape at the Point. The south cornerstone from the boundary survey remains in a seawall several yards south of the lighthouse.

Found this one today while on a bike ride exploring the renovated trails in Jones Point Part. Lots of new monuments around that show the boundaries of DC, MD, & VA.

Stumbled upon this on my way to a cache on a rainy Sunday afternoon. My first recorded Benchmark!

Found with the rangers of the NPS. Don't forget the mearby DC boundary stone!

Found with little trouble as it is near a geocache located nearby. Nice view of the Potomac River too.

Stumbled across this one on the way out after finding the nearby geocache. I'm not usually aware of these, but this one jumped up and bit me! Figured I ought to log it in.

Like the many others, found while geocaching this morning.

Stumbled across this benchmark while looking for a cache. I forgot that there were a few in the area.

This park is a benchmark gold mine. If I had known beforehand, I would have probably logged quite a few today.

This one will jump right out at you! Check all of the other nearby benchmarks and the Cache in this park.I hit the park at 10 AM on a Wed and pretty much had it to myself. Nice day, too. Canuman. Greer, SC.

Found while Caching with Cirrus and Freckle.

found it by accident while caching... seems to be a popular answer here

"WhatTrail?" and I ran across this one. Her entry gives some good info; Mistress Margaret Brent must have been quite a woman!

I had to laugh at Donbert's entry of 5/19 where he said that he had to clean the face of the marker before taking the picture: We had to do the same thing; I wonder if it's the same bird who may dislike this marker for some reason.

Found it after visiting the Jones Point Lighthouse while caching in area. Interesting trip--have included some pictures of/from the lighthouse.

Mistress Margaret Brent Marker at Jones Point Lighthouse: On September 6, 1654, this site was included in a patent of 700 acres granted by the Colony of Virginia to Mistress Margaret Brent (c1601 - c1671). An extraordinary woman, she spent most of her life fighting discrimination of her sex. She was the first private owner of the rectangular tract of land on the Potomac River above Hunting Creek that became the nucleus of Alexandria.

On my way to a nearby cache, I found the benchmark and remembered that there are benchmark waypoints. so I copied all of the info and Poof here I am. Another interesting mark (pun intended) in my history. Silver Fox+4

Found once again while geocaching.

Found this today, thinking that it was the 'elusive' southeast DC corner marker. Even though it was not, I cleaned the "bird poop" off of it to take a picture, and record the find.

There is one geocache hide nearby! The park is large enough for a couple more! - Donbert

Came back to visit the park and find this benchmark.

Found it while strolling with the dogs at Jones Point Park. Saw James Carville jogging in the park as well!

wilsonjl and Chelsea found this benchmark this afternoon while visiting Jones Point and the marker identifying the southernmost extent of the original District of Columbia.

Very prominent marker on tall concrete post. Larger (ca. 5 inches) than standard size disks. Arrow on disk points to river but no other marker found in that direction. Possibly, as noted by a previous log, this is due to relocation. Jones Point, once the site of a navy installation, is now popular with dogs and their human companions; see photo.

Edited to add the following information.

This is one of 58 boundary markers set in 1929 to delineate the Virginia-Maryland state line. Unlike most river boundaries, which run down the middle of the water, this boundary hugs the Virginia shoreline, except in some cases where it jumps the water, e.g. where a river enters, in a straight line. Because of erosion, most of these markers are now gone. The markers were set inland a bit and the arrow on each one points to a point on the boundary described by the surveyors. The stamping on this disk indicates where that point is: 42 feet from the disk in the direction of the arrow, which is 180 degrees, or due south.

Dreamer of Pictures and the Dreamer Team came across this on our way from the Jones Point lighthouse to the nearby geocache. This disk is quite prominent, standing above ground on its own concrete post in the midst of a wide path along the riverside. It apparently points to the southern cornerstone of the District of Columbia, 42 feet away, embedded behind a gate within the seawall of the lighthouse.

Found it by mistake while looking for geocaches in the area.

Note: the benchmark marked ''35 1990 AZ. MK.'', and pictured here by Docto is not HV1667. There is a ''GPS 35 AZ MK'' (HV9634), but it is not in the Jones Point area. I cannot find ''35 1990 AZ. MK.'' in either the Geocaching site or the NGS site.

This benchmark was found as described.

The marking on the benchmark is actually in three lines, and reads ''1929'' on the first line, ''No 58'' (?) on the second line, and ''180'' on the third line.

The disk is 5 inches in diameter; not the usual size. The square concrete post's corners are all broken off.

The benchmark is in a wide walkway heading East from the Jones Point Lighthouse.

We found this benchmark near the old Jones Point lighthouse. It was located within a fenced in area just west of the lighthouse. While searching for the proper benchmark to log with our coordinates, we found several markers, all of which are registered in the County of Alexandria. However, if you'll note, this benchmark is registered to Fairfax County.

But, in terms of coordinates, this is the closest to mine. Perhaps this BM isn't registered in the database?

Anyway, it's a nice place to visit! There is good parking, and some geocaches nearby... SaxRunner and I ran out of time looking for one, because we had to catch a flight up in Baltimore that afternoon.

Check the photos!

Control Text

  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in November 1994.
  • 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 Laplace correction was computed from DEFLEC99 derived deflections.
  • 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.
