Welcome back to the third and final release of the "Needful Things of West Seattle" series, and thanks for making your way to West West Seattle. These "Needful Things" are caches especially placed and titled for geocachers who, like me, are word challenge-obsessed. Most of the words in these colorful titles are useful for the Additional Logging Requirements on word-based challenge caches in the Western States (and Kansas!).
Sometimes, though, words (and especially colorful words) aren't the most useful way to communicate. To solve this two-stage multi-cache, park near the first stage. You'll be walking to the final from here. Look at the nearby telephone pole for two vertical metal plates. The lower one is a black field with gold numbers and the higher one is a yellow field with black numbers.
The container is at: N 47° 32.ABC W 122° 23.DEF.
A equals the first number on the black field added to the first black number.
B equals the fifth black number reduced by the third gold number.
C equals the second gold number multipled by the second black number.
D equals the sixth black number plus the second gold number plus the first number on the yellow field.
E equals the fourth black number subtracted from the final black number.
F equals the second to the last number on the yellow field increased by the third from the last number on the black field.
Happy Caching!
