A "Marvelous" Mystery
This geocache is not at the posted coordinates, but it might be a good place to park. There are at least two different ways to locate the cache using the information provided on this page. They involve using either "Decryption" or "Projection".
Perhaps you can think of other ways to get the location of the geocache. Good luck.
1. Vigenere Cipher (Decryption)
A 16th century French diplomat, Blaise de Vigenère, created a very simple cipher that is moderately difficult for any unintended parties to decipher. The Vigenère cipher is a method of encrypting alphabetic text by using a series of interwoven Caesar ciphers, based on the letters of a keyword. It is a form of poly-alphabetic substitution. You decode an encrypted message by using a key or passphrase. The letters of your passphrase determine how each letter in the message is decrypted.
To solve this puzzle, you'll need to "Decrypt" your message (cipher text) using the correct "Passphrase". Of course you'll have to figure out the passphrase, but that shouldn't be too hard. The following information may help:
| Passphrase: |
9 characters (think about it...) |
| Your message: |

| Geocache: |
N 47 20.??? W 122 12.??? |

2. Coordinate Projection
Given a starting coordinate, and the bearing and distance to the geocache, you can use coordinate projection to find this geocache. This type of calculation can be performed by many GPS receivers, but there are websites that will do the calculations for you. The following information may help:
| Coordinates: |
N 47 20.133 W 122 12.695 |
| Angle / bearing: |
16 degrees |
| Distance (in feet): |
