Geocache Description:


THE CACHE IS NOT AT THE LISTED COORDINATES!

To find the cache, you will need to solve a mystery based on photographs taken along the Columbia River in Astoria, Oregon.

The listed coordinates are a good place to start.  This is under the Astoria Bridge at Uniontown Maritime Memorial Park.  Parking is available.

The photographs below were taken along a 2.3 mile section of the riverfront.  This is a very enjoyable, scenic and historic walk (the "Riverwalk").  It also makes a fantastic bike ride.  Another option would be to walk the section and then return on the trolley.  On the trolley, look for this cache.

Your goal will be to locate the site each photo was taken from.  When you find a site, try to stand in approximately the position the photo was taken.  Using your GPS receiver, record the required digit for each photo as indicated below:

 

 
W 123 50.X75   A = X - 8 ___   
Note: The above site is a short distance from the trail and is very close to the starting point.  
   
 
W 123 50.X89   B = X - 1 ___  
Note:  The "Trolley" sign may be missing.  
   
 
W 123 50.X19   C = X + 8 ___  
   
 
W 123 49.X48   D = X - 8 ___  
   
 
W 123 49.X59   E = X + 4 ___  
   
 
W 123 49.X51   F = X - 3 ___  
   
 
W 123 48.X39   G = X - 3 ___  
   
 
W 123 48.X41   H = X + 4___  
   

 The photos are in order from west to east along the riverfront.

When you find a site, don't worry too much if the last digit or two of your GPS reading doesn't quite agree with those listed.

Once you have located each site and noted the required numbers, build the coordinates for the final cache using the letters indicated as follows:

N  46 1A.BCD

W 123 4E.FGH

To check the accuracy of your findings, apply a "checksum" test:  A + B + C + D + E + F + G + H = 38.

The cache is an ammo box.  Since this is a popular trail, please be discreet when retrieving the cache.  Be sure to visit the sea lions who live on the nearby boat docks.

If you need some help, send me an email and I will be glad to assist.
