This is a multi, not a mystery, stage 1 is at the posted coordinates.
There is no need to move stage 1 and possibly put it back a little off.
Stage 1 has a word on it, a simple, easy to remember, easy to spell word.
Just read it, you won’t get it wrong.
Take the word and turn the letters in to numbers using their place in the alphabet (A=1, B=2 ...).
Add the numbers together to get your word total.
Divide your word total by 1000 and add them to N 42° 29.087 to get the latitude.
Add that same number to W 073° 14.890 to get the longitude.
3 + 1 + 3 + 8 + 5 = 20
20 ÷ 1000 = .020
N 42° 29.087 + .020 = N 42° 29.067
W 073° 14.890 + .002 = W 073° 14.852
The final is walking distance from the swimming beach. It‘s a small lock & lock.
