It's there, right at GZ.

Well, I found something... not the benchmark. Lockmaster directed me to a tiny marker inside the lock itself. Will have to go back and find the real one sometime.

Can not miss this one. Between two thick white stripes on the wall. Sturdy, readable, good condition. Captain Jon Iroquois Sail and Power Squadron

Found the benchmark... still no luck with the nearby micro-cache! Beautiful location and Veterins Memorial. Nice carved brick path for memorial also. Benchmarks are fun!

Found this one while stopping for dinner at Lock 24. We were midway on a journey from Monroe Michigan to Solomons Island Maryland delivering a boat. Pretty spot right near the flagpole. I took a photo, will post later. :) Dang, there was a micro nearby too!! Should have checked for caches prior to our trip. Maybe next time.

Finally got this when the snow went off.

Stumbled onto this one while searching for the Lock 24 cache. It's been a while, since I've logged a marker, so here ya go.

Yep its there. Very easy to find. Pretty walk too.

No problem finding this benchmark. Just a quick walk down the canal as described.

Control Text

  • The horizontal coordinates were established by GPS observations and adjusted by the National Geodetic Survey in July 1997.
  • The orthometric height was determined by GPS observations and a high-resolution geoid model.
  • 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.
