I recently had a discussion with a coworker on the impacts to pothole aquatic life by canyoneers on the Colorado Plateau. Did a little research and found this fascinating scientific paper about pothole formation and how the biology actually impacts pothole erosion/creation. https://eurekamag.com/research/004/413/004413623.php From the abstract: “This complex biofilm is persumably(sic) responsible for dissolving the cement between the sandstone grains, allowing the potholes to enlarge, and for sealing the potholes, enabling them to retain water longer than the surrounding sandstone. Despite the remarkable ability of life in potholes to persist, desert pot-holes may be extremely sensitive to anthropogenic effects.” I’ll be plainly honest that I don’t plan to stop splashing through canyon potholes anytime soon but I am curious everybody’s thoughts on how the sport ethic can address preserving the aquatic habitat. Should we care about this? What methods can we use to reduce impact? How can we anticipate land management officials regulating pothole disturbance? Is it responsible to publish canyon routes (thereby increasing traffic) through this ecology? Is this making a mountain out of a molehill?
