Here’s a picture I took during our descent into Calgary Airport. Checking the GPS (which was running on the seat beside me) showed this to be a branch of the South Saskatchewan River, not too far from where the Bow River joins it. I found the erosion patterns to be quite striking from the air, and the Qu’Appelle valley region exhibits the same patterns. Whatever that soil type is down there, it sure is susceptible to erosion.
