I hiked up from the parking lot o n a hot afternoon to find this one.

Was up doing "Almost A DriveBy" Virtual Cache and had the cooridinates for this Benchmark, Forgot 3 of the other. Pretty soon I'll get the idea to put them on an SD acrd in my PDA and not worry about the paper anymore. Was clear and cold. We'll be back on a little warmer day for Congomerate Rocks and try and pick up the rest of these.

I happened to be in the area to complete a Geocache hunt with a friend and part of the plan was to find all the marks in this set. At the station mark my Garmin GPSmap76 receiver read approximately 7.6 feet from the posted coordinates. The disc was in excellent condition and legible. As Zhanna explained below, the RM2 reference mark was buried under a mat of moss, dirt and fine roots. The disc is in very good condition and the designation is legible. Reference mark RM1 was extremely difficult to locate due to the inadequacy of directions in the historic descriptions. It might have been a lot easier to find it without the snow and leaf cover since this disc was well exposed in the surface of the rock. It is in very good condition and legible. When hunting benchmarks I feel obliged to find [U]all[/U] the marks in the set, and this was one of the hardest sets I've done to date. Hopefully, the photos and GPS coordinates logged here will be helpful to other benchmark enthusiasts. ~Rich in NEPA~

Rich and I came back to Pimple Hill today to find the restored Conglomerate Rocks cache, and afterward we decided to hunt for the reference marks (in the snow). What fun it was! (Someone's going to wonder why the snow is scraped off all the 2' x 6' boulders in the area.) Rich unearthed RM2 pretty easily; it was on a boulder I'd noticed the other day, but I hadn't dug deep enough. RM1 was more of a problem because there was so little information provided to help us locate it. We spotted a few likely locations, but no marker. As we were about to leave (our feet were getting cold), Rich knocked the tiniest chunk of snow off some rock we'd already examined, and there it was sitting underneath! I think it was laughing at us the whole time. Well, at least we finally found the whole set, and we can sleep soundly at night.

Found it soon after the no-find at the nearby Conglomerate Rocks cache (we found out later that it was missing). The 1969 description was accurate and the disk was very easy to spot. It is in very good condition. I had other plans for the afternoon and didn't want to spend too much time looking for the reference markers; I took a quick look but didn't see them. I plan to come back on Thursday and search much more thoroughly!

Documented History (by the NGS)

1/1/1929 by CGS (MONUMENTED)
DESCRIBED BY COAST AND GEODETIC SURVEY 1929 (CMT) THE ORIGINAL STATION WAS FOUND AS DESCRIBED, EXCEPT THAT THE SURFACE MARK HAD BEEN APPARENTLY DISTURBED SINCE THE RECONNAISSANCE SURVEY HAD BEEN MADE, AS THE SURFACE MARK, A STONE WITH A CROSS MARK ON SAME, HAD BEEN UPTURNED. THE ORIGINAL SUBSURFACE MARK HAD, FROM ALL APPEARANCES, NOT BEEN DISTURBED. NO OLD REFERENCE MARKS WERE RECOVERED. THE STATION IS LOCATED IN TUNKHANNOCK TOWNSHIP ON THE SSE HUMP OF PIMPLE HILL, A KNOB OF THE POCONO MOUNTAINS, ABOUT 1/3 MILE TO THE SW OF THE EASTON HIGHWAY. IT IS ABOUT 7 MILES NW OF THE VILLAGE OF EFFORT AND IS SITUATED ON LAND OWNED BY THE SHUPP HEIRS. IT IS ON THE CREST OF THE HIGHEST HUMP OF PIMPLE HILL. THE STATION WAS REMARKED AND TWO NEW REFERENCE MARKS WERE ESTABLISHED. THE SURFACE MARK IS A STANDARD BRASS STATION MARK SET IN TOP OF A LARGE BROWN SANDSTONE, ABOUT 12 BY 18 INCHES ON TOP, NEAR THE CENTER OF A LARGE ROCK PILE, AND 2-1/4 METERS W OF THE OLD ORIGINAL TOPOGRAPHIC STATION WHICH CONSISTS OF A LEANING POLE SET IN THE CENTER OF A LARGE CAIRN. UNDERGROUND MARK IS A STANDARD BRONZE DISK WEDGED IN A DRILL HOLE IN BEDROCK AND OCCUPIES THE SAME POSITION IN THE ROCK AS THE ORIGINAL SURBSURFACE MARK. REFERENCE MARK NO. 1 IS A STANDARD BRONZE DISK SET IN TOP OF AN OUTCROPPING ROCK LEDGE ABOUT 6 INCHES ABOVE THE SURFACE OF THE GROUND. REFERENCE MARK NO. 2 IS SSE OF STATION AND CONSISTS OF A STANDARD BRONZE DISK WEDGED IN TOP OF A LARGE BOULDER 3 BY 6 BY 1 1/4 FEET. THE STATION IS REACHED FROM THE DIRECTION OF WILKES BARRE BY ROUTE NO. 115 SE ABOUT 24 MILES TO BLAKESLEE, WHERE IT TURNS TO THE LEFT. AT BLAKESLEE KEEP STRAIGHT AHEAD ON THE EASTON ROAD THROUGH FERNRIDGE, ABOUT 2 MILES BEYOND BLAKESLEE, AND ON TO A POINT 4.7 MILES BEYOND FERNRIDGE POST OFFICE, TO A POINT JUST E OF THE SUMMIT OF A GRADE, AT WHICH POINT A WOOD ROAD TURNS TO LEFT AND A BORROW PIT IS ON RIGHT-HAND SIDE. THE BORROW PIT IS ENTERED BY A TURNOUT OVER THE EXPOSED END OF A CORRUGATED-IRON CULVERT. FROM HERE A TRAIL LEADS ABOUT 3/8 MILE TO A FLAT SADDLE ON TOP OF PIMPLE HILL TO SW. LEAVE TRAIL AS SOON AS SADDLE IS REACHED AND BEAR LEFT ABOUT 1/4 MILE TO THE HIGHEST PART OF THE KNOB, WHERE THE STATION IS LOCATED. HEIGHT OF SIGNAL ABOVE STATION MARK - 1.5 METERS.
1/1/1955 by CGS (SEE DESCRIPTION)
RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1955 (IWS) THE ORIGINAL DESCRIPTION IS CORRECT WITH THE FOLLOWING CHANGES- THE STATION MARK IS 58.2 FEET NORTHEAST OF THE CENTER OF THE LOOKOUT TOWER. THE LARGE CAIRN NEAR THE STATION HAS BEEN REMOVED. TO REACH THE STATION FROM BLAKESLEE CORNERS ON ROUTE 115, GO SOUTHEASTERLY FOR 3.3 MILES TO THE JUNCTION OF ROUTE 903. CONTINUE SOUTHEASTERLY ON ROUTE 115 FOR 3.1 MILES TO A TRACK ROAD RIGHT. TURN RIGHT AND GO 0.7 MILE UP MOUNTAIN TO THE STATION SITE.
1/1/1958 by CGS (SEE DESCRIPTION)
RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1958 (JMR) THE STATION MARK, REFERENCE MARKS NO 1, NO 2 WERE RECOVERED AS DESCRIBED AND FOUND IN GOOD CONDITION. A DIFFERENCE WAS NOTED IN THE DISTANCE AND DIRECTION TO THE MARKS. THIS MEASUREMENT WAS DOUBLE CHECKED IN THE FIELD AND IS BELEIVED TO BE CORRECT.

IT IS ABOUT 24 MILES SOUTHEAST OF WILKES-BARRE, ABOUT 7 MILES NORTHWEST OF THE VILLAGE OF EFFORT, ABOUT 5 MILES SOUTHEAST OF BLAKESLEE CORNER, ABOUT 0.3 MILES SOUTHWEST OF STATE HIGHWAY 115 AND 58.2 FEET WEST-SOUTHWEST OF THE CENTER OF THE POHOPOCO FIRE TOWER.

Control Text

  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in September 1999.
  • 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.
