Beautiful station and a well cared for BM disk. Watch your step while photographing -- this is a VERY BUSY rail line, and there isn't much room for error!

It looks like maybe there was some remodeling/restoration done to the area within the last few years and this may have affected the quality of the mark. Previous photos look pretty sharp, but the stamping on the mark is becoming very difficult to read. It is still there, however.

Moments after photographing the disc, a train thundered through. Kingman is still host to dozens of trains a day...

got it

A nice and easy find. But there are a few fine points to the description.
First, the Ticket Office and the Freight Office are connected, so the disk is located about 15 feet east of the far western end of the structure. You can tell where the 2 join because the Ticket Offices southern wall is about 4 feet farther south the the Freight Offices southern wall.
Second, the Platform is gone.
Third, the Walk is gone.
Instead of these concrete bits, there is now "Ballast" that large gravel that supports railroad tracks.
If all of this sounds confusing, just go check it out. It is actually a good one.

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.
