The above coordinates are NOT the
coordinates of the cache, they are the coordinates for the
first stop along this multi.
You will need to gather info at each of the 4 stops to figure out
the location of the final cache, which will work out to be:
N 45° 23.ABB
W 123° 48.CDD
[1st stop]
Go to N45° 29.067
W123° 50.679
Look 315° magnetic (northwest) and count the number of letters in
the 2-word name of the boat.
{Number of letters} minus {3} = A
[2nd stop]
Go to N45° 28.019
W123° 50.575
Look due north and count the number of letters in the 2-word name
of the company.
{Number of letters} plus {70} = BB
[3rd stop]
Go to N45° 27.429
W123° 50.570
Read the sign at that location and determine the year the stone
was donated.
{Year stone was donated} minus {1949} = C
[4th stop]
Go to N45° 25.235
W123° 48.207
Look due East at the old sign.
Take the {Big number} minus {Little number}, then add {72} =
DD
[Final cache location]
Plug the numbers you've figured out into the location:
N45° 23.ABB
W123° 48.CDD
Which will bring you to the final cache location.
Happy hunting!!
