“When I am Playful I use the meridians of longitude and the parallels of latitude for a seine, and drag the Atlantic Ocean for whales” –Mark Twain
“Consider the lines of longitude,
How they cover the Earth head to foot,
How they expand in the heat,
And contract in the cold,
But will always stay right where they’re put.” -EraSeek
WHAT YOU NEED TO KNOW:
There are several unique things about this cache.
1.The above coordinates will do you no good. They will put you on the deck of the Kalakala. (yes, really.)
2.This is a virtual cache. No box, no prize, no logbook. There are several reasons for this, but mostly because of the nature of the property and also to give everyone a chance to try out a virtual cache.
3. The gates close at 7pm.
4. The actual coordinates you are looking for are a bit different. They are:
N47° 41.127’
12:09:00.03816 Pacific Standard Time (Local Noon at the cache site)
You must covert local noon to degrees longitude. To avoid going through the date adjustments and such I'm using the passage of local time, not solar transit. To be most precise, I am using UTC not UT1 as a basis.
5. You are looking for a date. Careful! There are other dates about. This one is not paired with another. To log a successful find you must match the date with the encrypted date in the hint below.
This cache makes you think about longitude and how it works. Where latitude is a function of distance and angle, longitude is largely a function of distance and time. You must figure out how local noon relates to degrees of longitude. If a math numbskull like me can do it so can you. Once you think about it, it is not really that tough.
What ARE these things around you?? There are many interesting things here if you look about! Have fun!
