Black Magic Canyon in south central Idaho. Sad to say some of the formations are now showing signs of graffiti and vandalism. I wonder sometimes if it would have been better to not show any photographs of this unique and amazing place but for the most part - as usual, awareness wins that debate for obvious reasons.
I spent more time in a deeper section during this last trip and became aware of something I hadn't fully realized before. Although the dominant colors in the carved basalt are of course black, gloss black and gray, light reflected off adjacent rock reveals different color hues ranging from light blue, to tan and sometimes varying shades of purple. It would take a much better writer than I to adequately describe the color changes depending on the angles of reflected light in this canyon that is an exquisite example of art in nature.
Over a period of about ten thousand years, the Big Wood River carved these sculpted forms in the hard basalt. So, someone in this time comes along and chisels their name and some verbal garbage - I would suggest not doing that.
Very Important information if you plan a visit: The water is now controlled by the Big Wood Canal Co. in Shoshone and the canyon is full during the irrigation season so early spring and fall are clearly the best times to visit. If you plan a visit you must call the canal company first. If you are in the canyon when they release water from the dam, it would be like a southwest flash flood in a slot canyon and there would no escaping. The number to call is 1-208-886-233.
