The choice is either to start at the dam in Montana and go up the canyon by boat or to start in Wyoming and take in the views from the rim. It was a long way for me to dodge power boats without easy stopping points, and the water level is obviously artificial. So, I chose to admire the views from above, passing through the wild horse refuge area and finding Devils Canyon Overlook above. I didn’t see any horses, but a turkey vulture flew right by my head so close the loud whoosh and sudden breeze startled me. Maybe he was hoping I’d fall over the extremely steep edge.

The topography of the area is disconcerting, as you see mountains & high ground and assume the Bighorn River would run south, but for all the uplift, the river has just carved its way deeper through the partially flooded canyon. Far upriver further south, it does the same thing, but there it’s called Wind River and cuts through Wind River Canyon. Ultimately, the basins and lesser mountain ranges in Wyoming matter far less to the river direction than the Rocky Mountains, which on this side of the Continental Divide cause the rivers like the Shoshone and Bighorn to flow east and north, joining here before flowing into the Yellowstone River on its way to the Missouri River. In the photo above, that flow is from the upper right to lower left, below the large shadow on the cliff across the canyon. The stretch of water in the upper middle, below the fans is Devil’s Canyon, partly filled by the dam’s backwash and sometimes fed by Porcupine Creek. The foreboding names match the inhospitable scenery. This is a rough and remote area, but it’s also starkly beautiful and dramatic.
