Geocache Description:


The cache is not at the listed coordinates.  Please solve the puzzle below to find the actual location.

 

This is one of two new photo caches that replace and upgrade GC24K9T - Astoria Riverwalk Photo Cache.  Its partner is Astoria Riverwalk East.

 

---------------------------------------------------------------

 

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

 

Start at the listed coordinates.  This is the Columbia River Maritime Museum.  Parking is available.  After finding the first photo, continue by walking west.

 

The photographs below were taken along a one mile section of the riverfront between the Museum and the Maritime Memorial Park.  This is a very enjoyable, scenic and historic walk (the "Riverwalk").  It also makes a fantastic bike ride.

 

Your goal will be to locate the site each photo was taken from.  When you find a site, read the question below the photo.  You should be able to answer the question by looking around the area near the photo site.

 

 

What number is on the rusty metal pillar to the west?

 

A = ____

 

 

 

How many letters are below "SANDRA & HOWARD" on the office door to the right?

 

B = ____

 

 

 

How many boards wide is the surface of the ramp?

Be sure to count the narrower one on the north edge.

 

C = ____

 

 

 

As you enter the bridge to the west, what number is on the green street sign?

Update 7-24:  The ship has sailed during building maintenance!  D = 2

 

D = ____

 

 

 

How many posts rise out of the river between you and the object in the photo?

Count just the taller posts and not the random stubby ones visible at lower tides.

 

E = ____

 

 

 

What are the last two digits of the year in which the Memorial was dedicated?

Look between the two pillars.

 

F = ____

 

 

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

 

Build the coordinates for the final cache as follows:

 

A + B + C + 437 = XXX

 

D + E + F + 483 = YYY

 

The cache is at:

 

N  46 11.XXX

 

W 123 50.YYY

 

Checksum:  The total of the 15 digits of the coordinates should be 59.

 

Take a well-earned seat at the Memorial Park and plug in the coordinates for the cache.  You can find it on the way back to the Museum.  Since this is a popular trail, please be discreet when retrieving the cache.

 

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

 

Have fun!
