This cache is located in the Chalco Hills Recreation Area.
The coordinates above are not the actual cache coordinates; just the nearest parking coords. Requested and received permission from the Papio NRD to place this cache. Up to about 275 feet out, it is all bikepath, but there is some offtrail walking toward the end. The cache is at 41 degrees north and 96 degrees west. And that's all I'm going to say!
In order to find the coordinates for both Chalogical #1 and Chalogical #2, you will need to solve the logic puzzle listed below. In addition to the clues I’ve given, you will need information from my other three Chalco caches in order to get the correct solution. Those who have already found the other three will have a headstart, but you will be able to solve the puzzle just by using information from the geocaching.com listings for each cache. You can use the grid below to help you; just click on the link 'Logic Puzzle Grid', resize it to full size, and print it out. Commonly in logic puzzles such as this, a dot in a column or row means ‘yes’, while an ‘X’ means ‘no’. Eliminate the obvious, use your head, and you’ll find the answers! Each cache is in a different container, at a different set of coords, and is hidden in, at, or by a different physical structure. (Well, almost. Yes, there are two rock piles. I am Sioneva. It happens!)
1) Both north and west minute coordinates for both Chalogical #1 and Chalogical #2 are exactly the same number, and the north equals the west.
2) The northern coordinate for the lock-n-lock is exactly .847 less then the northern coordinate of the big rock pile.
3) The cylindrical Tupperware is hidden at “No Rocks Were Used”.
4) Chalogical #2 is not concealed by or with wood or wood products (for the purposes of this puzzle).
5) The lock-in-lock is not hidden in the rocks, or at “Something’s Fishy”.
6) The northern coordinate for the Tupperware at “Unnatural Pile of Rocks” is exactly .594 more then the northern coordinate of the small rock pile.
7) The decon container rests at 41° 09.759 N; this is not where you find the small rock pile.
8) The tree grows at 09.932 W. There is nothing fishy about pine needles.
9) The west coordinate of the ammo can is exactly .003 less then the west coordinate of the lock-n-lock, which is exactly .789 less then the west coordinate for “No Rocks Were Used”.
10) Pretend that "Something's Fishy" is still under the platform. I'm sorry I had to move it!
The theme for both caches is puzzles and games. I've left appropriate swag.
UPDATE 4/23/07 - Changed puzzle to reflect cache changes. Updating puzzle grid as well!
