Pseudoku - a puzzle cache Mystery Cache

This cache has been archived.

Nylimb: Thanks to hidegoseek for letting me know that the cache location will be off-limits for quite a while. Normally I'd replace it in a different location and adjust the posted coords to match, but that's not going to happen during the pandemic. So I'm archiving it.

Thanks to everyone who solved the puzzle and/or found the cache.

Geocache Description:

The cache is on the North Spit of Humboldt Bay; it is not at the listed coordinates. It is only accessible during daylight hours; there's a gate near the Coast Guard station which is locked half an hour after sunset.

To find the cache's location, you'll need to solve the Sudoku-like puzzle below:

Here's how it works. You need to put one letter in each of the 64 squares of the grid above so that:

1. The letters shown to the right of each row are an alphabetical list of the letters in that row.

2. The letters shown below each column are an alphabetical list of the letters in that column.

3. For each of the 14 'cages', defined by the thick black lines, the letters in the cage can be arranged to form a common English word. (At least, it's common among geocachers.)

(Note for people familiar with Sudoku puzzles: You are allowed to use a letter more than once in a cage, as long as the occurrences are not in the same row or column.)

I've filled in some letters to get you started. When you've figured out all the words, you can arrange them to form two sentences which describe the cache location. Adjacent words in the description come from cages which share part of their boundaries, and the first word comes from the top left cage.

If you think you've figured out the coordinates, you can check them with certitude:



You can also see who else has solved the puzzle. Note: You can remain anonymous if you want to; incorrect guesses are always anonymous. (Puzzle makers, you can create your own certitude links here.)

Or you can check your coordinates here: Geochecker.com.

Once you have the coordinates, the difficulty level drops to 1.

The cache is a small snap-lock container, with room for geocoins or small travel bugs.

There may be muggles in vehicles in the area, but you can probably see them coming in time to disguise your activities.



Congratulations to hidegoseek for FTF!



In case the puzzle description isn't clear, here's a simple example, with a smaller grid divided into 4 cages:

There's only one way to put letters in the grid as described above:

Unscrambling the letters in each cage, and arranging the words as shown by the arrows, you can form the sentence "THIS PUZZLE IS EASY".
