a bit of it left. Bad shape

I found what's left of it... It's in poor condition!

Didn't take a picture. Think it is a lot less then 20" from the edge now.

Found the remnants of the mark today after logging an earthcache near here. Found the stem of the mark with the aid of a metal detector about 2" under the soil and about 20" from the edge of the bluff. This mark and its foundation may soon be lost to the forces of erosion

Mark is in poor shape.

mark still in bad condition, with stem exposed.

The station is in poor condition at the posted coordinates. The disk is missing but the stem is intact. New directions follow.
From the Ohio-Pennsylvania state line marker on US Highway 20, go 1.4 miles east on US Highway 20 to a side road left. Turn left and go north for 2.6 miles on Rudd Road to a T-intersection. Turn left and go west on Old Lake Road for 1.4 miles to a Pennsylvania State Game Lands parking lot on the right and the end of vehicle travel.
From the parking area, follow a footpath north and west for about 260 feet to the edge of the bluff and the station. All cottages in the 1975 description have been removed. The mark is now 3.0 feet southwest of the edge of the bluff overlooking Lake Erie.

ATOP A HIGH BLUFF OVERLOOKING THE LAKE ON THE FRONT YARD OF A GROUP OF COTTAGES OWNED BY THE U.S. STEEL CORPORATION. TO REACH THE STATION FROM THE INTERSECTION OF U.S. RTE 20 AND OH RTE 7 AT CONNEAUT, PROCEED EAST ON RTE 20 FOR 2.0 MILES TO THE OH/PA STATE LINE AND STATE LINE ROAD ON THE LEFT. TURN LEFT, NORTH, AND CONTINUE FOR 2.20 MILES UNTIL THE TERMINATION OF STATE LINE ROAD AT LAKE ROAD NEAR LAKE ERIE. TURN RIGHT, EAST, AND CONTINUE FOR ABOUT 500 FEET AND A GROUP OF 6 SMALL COTTAGES ON THE LEFT. THE STATION IS LOCATED JUST NORTH OF THE FOURTH COTTAGE EAST OF THE STATE LINE (VICINITY OF UTILITY POLE NO. 34245 WHICH IS 100 FEET NORTH OF LAKE ROAD AND JUST SOUTH OF THE FOURTH COTTAGE REFERENCE). STATION MARK IS A STANDARD NOS BRONZE DISK SET FLUSH WITH THE GROUND AND STAMPED STATE LINE LSC 1975. AND IS LOCATED 52.9 FEET NORTH OF THE COTTAGES NORTHEAST CORNER, 55.7 FEET NORTHWEST OF THE COTTAGES NORTHEAST CORNER, 11.0 FEET EAST OF AN 8 INCH DECIDIOUS TREE, 9.8 FEET SOUTH OF THE ERODING BLUFF OVERLOOKING THE WATER.

THE STATION AFFORDS GOOD VISIBILITY TO ALL POINTS SEAWARD.

Control Text

  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in April 1998. No horizontal observational check was made to the station.
  • The NAVD 88 height was computed by applying the VERTCON shift value to the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
  • The Laplace correction was computed from DEFLEC99 derived deflections.
  • The geoid height was determined by GEOID99.
