This is one of our favorite spots to take a break and picnic of anywhere in the park. This site is a little off the beaten path and easy to miss. You can drive right up to it though (although do not drive large RVs down this road, there is nowhere to turn around if you do, signs are posted).
This particular tribe of Shoshone were the "Amish" of their time, they stuck with the "old" ways of doing things, and didn't even take up the horse when it became availible believing it was too "new-fangled". They primarily hunted Bighorn Sheep as a mainstay of their existance thus earning them the nickname of "Tukadika" or "Sheepeaters". They used the horns of the sheep to form bows by treating them in the scalding waters of some of the geological features in Yellowstone. After being treated thusly these bows could drive an arrow through two consecutive Bison standing side-by-side.
When you reach the location you'll be in front of a sign that explains how the cliff just behind the sign was formed, what it is formed of, and what the geological formation is called.
On the back of this sign are a series of letters and numbers engraved in the wood. These are official numbers of the Park Service, not anything placed there for Geocaching. There are three letters above a series of four numbers. Please send me the letters and numbers in an email to claim this cache. Please DO NOT place the information in your log post, not even encrypted, or I will be forced to delete your log. I had to change the requirements once the sign, and it's content, were posted on the internet in many places. Once you see this part, hike east on the trail along the river and you will come to a second instance of the same kind of formation, only fewer people and more quiet. Even further down the trail you will come to a very nice waterfall.
