Dwarves' Earth Treasures Museum:
Tee Pee Canyon Agates
Tee Pee Canyon, Black Hills, South Dakota		 .
    The Tee Pee Canyon Agates in form of concretions can be extracted up only by hands (hard work!) as according to the National Forestry officials. The agates came from a hard limestone formation on the west side of the Black Hills, and may have shared the same limestone formation as more famous Fairburn agates but formed under different enviroment conditions.
    It appears that the agates tend to follow the fixed order of most common colors: red, yellow, and lastly white, but that is not alway true. It is my experience that agates in Tee Pee Canyon concretions tend to be narrow, irregular and somewhat unpredictable, meaning that just because you can see a spot of good agate on a nodule won't mean that the agate will widen to take up more space within the nodule, plus that agates are not always centered within the nodules either and that is obviously why some people slab them up. Any agates taking up 35% or more within intact concretions are quite rare.
