This is latest addition to Mr. GeoKs' flock (sic) of not-so-simple birdhouse caches. If you're in the Three Sisters neigbourhood working on our MBT or Three Sisters Parkway Challenge series of caches, consider this a bonus hide for your caching enjoyment. This cache is located about 25 steps off a well-established dirt path frequently used by walkers and mountain bikers.
Magnetoception is a sense which allows some organisms - including birds - to detect a magnetic field to perceive direction, altitude or location. For the purpose of bird navigation, including seasonal migrations, magnetoception deals with the detection of the Earth's magnetic field. For the purpose of signing the log for this cache, magnetoception just might come in handy!
All items necessary to access the waterproof bison container holding the log sheet are stowed at the cache site. Brute force is NOT required. Brain power IS required. If you can't access the bison tube container, there's probably something you overlooked or haven't yet figured out.
NOTE: This area is frequented by wildlife, including elk, deer and occasionally coyotes, bears and/or cougars. Please be WILDSMART - make lots of noise while riding and carry bear spray.
