> My take: A quickening erosion cycle could see an accelerated creation of arches I think increased erosion would also cause arches to fail faster (run through its lifetime at increased speed). I think there is no limit to how fast an arch can erode (ie. the erosion can easily speed up orders of magnitude) but at the same time I don't think we could be seeing orders of magnitude more arches created, which would be necessary to maintain the number of arches that are now going through their lifecycle faster. This lets me believe that overall increased erosion would cause less arches to be present at any point in time. This is just a thought experiment, I have no data to back it up.
