Mario5 pretty much said it all about this one that we did together.
One other note: this benchmark and dim road are just past the back side of H.P. Starr (lumber/hardware place) as you are going away from Evans City.

This one was a bit tough to find - in fact I walked right past it (within inches). Didn't have my GPS with me, but copydeskadam did. Coordinates are close (though I seem to recall them leading to the wrong side of the tracks). Measurements listed are close as well - this one is quite hidden in overgrown vegetation on a slight rise. It is also no longer standing upright.

Will try to upload pictures (only had my cell phone camera, so apologies for the quality)

Can't see it, but it's behind copydeskadam (guy in the blue shirt). The 'dim road' is at the far left.

DESCRIBED BY COAST AND GEODETIC SURVEY 1954 1.2 MI NW FROM EVANS CITY. ABOUT 1.25 MILES NORTHWEST ALONG THE BALTIMORE AND OHIO RAILROAD FROM THE STATION AT EVANS CITY, ABOUT 1.3 MILES SOUTHEAST OF MU CONTROL TOWER AT EIDENAU, AT A DIM ROAD CROSSING, 16 FEET SOUTHWEST OF SOUTHWEST RAIL OF SOUTHWEST TRACK, 71 FEET WEST-SOUTHWEST AND ACROSS DIM ROAD AND TRACK FROM TELEPHONE POLE NO. 29/20, 33 FEET WEST OF CENTER OF CROSSING OF SOUTHWEST TRACK AND DIM ROAD, 23 FEET NORTHWEST OF CENTER LINE OF DIM ROAD, 2 FEET EAST-SOUTHEAST OF A WHITE WOODEN WITNESS POST, ABOUT 1 FOOT ABOVE LEVEL OF TRACKS AND SET IN THE TOP OF A CONCRETE POST PROJECTING 3 INCHES.

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.
