Visited Yellowstone National Park for the first time. A bucket-list item for me. Spent the night in Gardiner, Montana, took lots of pictures, and did a few touristy things. Looked for a few benchmarks too. The highlight for me was the massive Roosevelt Arch at the north entrance of the Park. Built in 1903 by the US Army, the cornerstone was laid by President Theodore Roosevelt.

Located in the Town of Gardiner, Park County, Montana, this NGS mark lies near the Roosevelt Arch. The NGS mark stamped "D565 1983" was found at 08:30, 24 July 2019 as described and in good condition. To be expected with a mark that's less than 40 years old. Go to description is adequate to find the mark.

Published NAD83 coordinates are located about 323 feet southeast of the found WGS84 coordinates. WGS84 coordinates for the mark found by 4 minute occupation with 11 strong satellites and 1 WAAS satellite.

Spotted by chance when getting some pictures of the Arch.

Had to return a second time to get the pic as a herd of mule deer was also benchmarking on the first try

Coming out to the arch and standing on the same ground as T.R. was our primary goal today. Finding a nearby benchmark was the bonus.

Not too much trouble finding this one, since there wasn't much snow on the ground yet.

We found this by the arch into Yellowstone. The arch was crowded with a bus-load of tourists taking pictures!

My first Montana benchmark! Found with MomLady. Wasn't there some really neat arch or something nearby?

Found with TrekkinD.

DESCRIBED BY NATIONAL GEODETIC SURVEY 1983 0.3 KM (0.2 MI) SOUTH FROM GARDINER. 0.3 KM (0.2 MI) WEST ALONG MAIN STREET FROM ITS JUNCTION WITH U.S. HIGHWAY 89 IN GARDINER, AT THE ENTRANCE TO YELLOWSTONE NATIONAL PARK, IN THE CENTER OF A 3 BY 3 FT EXPOSED AREA OF OUTCROPPING BEDROCK PROJECTING 0.3 METER (1.0 FT) ABOVE THE GROUND, 23.3 METERS (76.4 FT) EAST OF THE CENTER OF THE ARCHWAY ENTRANCE TO THE PARK, 17.4 METERS (57.1 FT) SOUTHEAST OF THE NORTHEAST END OF THE ROCK WALL, AND 14.4 METERS (47.2 FT) NORTHEAST OF THE CENTERLINE OF THE YELLOWSTONE NATIONAL PARK ENTRANCE ROAD. THE MARK IS 0.3 M ABOVE THE ROAD.

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.
