Scaled coordinates are off quite a bit as I found this about 100 yds South of Shaffer Road which is a private dirt road for the Blooming Grove Hunting & Fishing Club. Please contact Scott, contact info listed in the NGS datasheet, before entering and sign a waiver.

Found R235 and replaced the pine needles to cover back up. Neat find and always curious who lived here and why all the glass bottles but no other garbage..

This proved to be an exciting find! I love coming across manmade structures in the woods. We began our search too far north at a private road leading to some hunting cabins. We soon determined it was unlikely that a house had ever stood at this location, and we walked south on PA Route 402 for just over 100 yards until on our right we noticed a level area covered in young pine growth. Entering the woods at this point, we saw the steps immediately, and off to their right was a decrepit stone foundation filled—and surrounded—with old glass bottles, rusted cans, and other junk such as a child's rusted bed mattress. The mark was found on the steps exactly as described, and it appears to be in excellent condition with all stamping legible.

[i]An official report of this station's condition was submitted to NGS, along with the following recovery note:[/i]

Recovered in good condition. The mark is located approximately 120 yards south along PA Route 402 from a private road leading southwest. The apple tree no longer exists.

This second order vertical control station is set in the center of the top surface of the second step of an old concrete stair platform along U.S. Rt. 402, roughly 120 yards south of a private woods road west. The historical description is still usable, but the apple tree no longer exists. At the station a Garmin GPSmap76 receiver with remote active antenna was used to record autonomous (non-corrected) coordinates which were 380 feet from the scaled coordinates listed on the NGS datasheet. The mark is well exposed, in good condition, and the stamped designation is clearly legible. ~Rich in NEPA~

Documented History (by the NGS)

1/1/1959 by CGS (MONUMENTED)
DESCRIBED BY COAST AND GEODETIC SURVEY 1959 11.4 MI SE FROM HAWLEY. 8.5 MILE SOUTHEAST OF HAWLEY TO THE GOOD SHEPHERD CHURCH THENCE 2.9 MILE SOUTH ALONG STATE HIGHWAY NO 402, SET IN TOP CENTER OF THE SECOND STEP WHICH WAS FOR A HOUSE WHICH HAS BEEN DESTROYED (STEPS ARE THE ONLY PART OF THE HOUSE LEFT), 16 FEET NORTH OF A 2 1/2 FOOT APPLE TREE, 60 FEET WEST OF AND ABOUT 2 FEET ABOVE THE CENTERLINE OF THE HIGHWAY.

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.
