Math Taxi and the Xenolithic Bump - CCARF11 Mystery Cache

This cache has been archived.

iMinions: Unfortunately this cache has been muggled. There seem to be a lot of nearby occupants based on the discarded tents and clothing so I'm going to archive this instead of replacing it.

Geocache Description:

A two part math puzzle cache. The first step is to solve a mathdoku to get to the correct cache coordinates. Once you find the cache you'll need to solve a simple math puzzle in the field to open the container.

The cache is NOT at the posted coordinates.

This is a permanent cache, it was placed for the CCARF11 event, held October 22-23, 2011 and remains in place.


Fiddle de dum, fiddle de dee,
A ring around the moon is π times d;
But if a hole you want repaired,
You use the formula πr2.

Step #1: The Mathdoku

The first step in finding this cache lies in solving this Mathdoku puzzle.

The rules for the puzzle are easy:

  1. Use only the digits 1-4
  2. Each row contains exactly one of each digit with no repeats
  3. Each column contains exactly one of each digit with no repeats
  4. Each bold-outlined group of cells contains a clue with a number and symbol. The symbol represents the mathematical operation and the number represents the result. For example, if the clue for a group of 2 blocks is "5+", some possible answers could be 1+4 or 2+3

Step 2: Produce the Final Coordinates

Once you've solved the puzzle you can use that to come up with the final coordinates for the cache...

N 51° 09.[I-O][E+L][D] W 114° 11.[E+K+H][B-P][A+J]

You can check your answers for this puzzle on Geochecker.com.

Step 3: Find the Cache

We'll assume everyone is comfortable with this part of the process :) We recommend starting at the indicated parking point. From there you can follow the pathway toward the cache until the pathway ends (park still in progress). Follow the foot trail straight ahead about 40m until it intersects with the other walking path. From there you follow the path up and cut straight across the field to GZ. And be careful. There are a lot of burrs along the way.

Step 4: Open the Cache

To open the cache you'll need to solve a simple math puzzle in the field. If addition is not your friend, you may want to drag along a calculator.
