Lawrence Line Survey

Back in 2015 I happened to be near where the Lawrence Line intersects the Delaware River between NY and PA. I photographed this stone with a hole in it. I believe this is THAT stone, but I didn't find any initials in the stone. I lack the map skills to take this lat/lon and plot it on a map to see if I was correct. If this isn't the correct stone, it's very close to the real one.

I believe you are correct. The line lines up with your stone. However, your cords are off somewhat as they are in a field along the north edge of Rodano Drive. Can you look the below photo over and pinpoint the stone along the river?

Looking again at this it must not be the exact rock. The line is off by about 1400 feet at Cox's Rock. But in reality it is quite close to the location.

You already have your GPS set to decimal degrees, so it's actually quite easy. North means positive numbers and West is represented by a negative number. So for your first screenshot we get this for Latitude, Longitude

41.71200, -75.05658

Enter those numbers on my maps using the little "sphere" icon on the toolbar

And you get this location, which is (apparently) in the middle of the river.

Doing the same for the other screenshot yields this

41.71499, -75.05977

You can then switch between other maps and aerials using the map menu button at the top right of the screen.

Okay. I am pretty certain it is this rock. The cords are off at the other one. Now the line alligns.

The location of Anthony's first gps coordinates looks very good on the south side of the river. The last coordinates end up in a field on the north side.

Even that stone does not align. I will have to research this more.

I am unsure what first and last you are referring to. The first cords he posted in post 82 are on the north side of the river in a field.

I ran a line using google Earth from Lawrence Line #10 which I have multiple survey maps giving the same coordinates, all the way past Waterloo Village to the Delaware and it allign very closely with all the points I know and it ends up in the circled area on this map. The left line was Anthony's stone, the center one was the one I originally felt was my correction and the circle is where it runs to.

That's weird, maybe they display in a different order for you? This is what I see, and the first attachment (the one on the left) is as I described above. The coordinates you posted are in the fourth image in my browser.

I think there is some confusion on both sides. I was looking at the cords for the 4th photo and was writing about his "first post." Why do we have conflicting coordinates????

Even using the cords in the first photo put it dead in the center of the river. In any event, it may be the proper stone but the line does not line up with it. That may be how it is since Lawrence did have some issues getting it straight.

Yeah, definitely some confusion! :) I was talking about the image IMG_0199.JPG, which is the first attachment (the one on the left) in post #82. The coordinates displayed in that image are 41.71200, -75.05658
