This is a letterbox hybrid geocache. If you are not into letterboxing, you can treat this just like any other geocache. There is a logbook to sign, and trinkets to trade. But for you letterboxers, there is a second book for stamping, a stamp to make an impression in your personal stamp book, and an ink pad. Of course everyone should know that the letterboxing paraphernalia is not for trading, and should remain in the cache.
The Yellow Cliffs are a well known feature near the northern end of Bartlett Lake. The rocks of the cliffs take on their yellow coloration due to an extensive colony of yellow "crustose" lichen. Lichen is a fascinating organism. Actually it is not a single organism, but a symbiotic community of algae or cyanobacteria living with a fungus. See the Wikipedia article on lichen to learn more about this interesting composite organism.
The view from the cache is breathtaking. Getting here is a bit of a challenge, but if we did it, so can you. There is a "good" way to get here. Your challenge will be to find the good way, and not take one of the many not-so-good routes!
