That really doesn't happen. Each ascent we make leaves a subtle trail, that gradually builds with repetition. It starts far away, when a person drives a relatively gas-guzzling 4x4 to a trailhead, or alters the habits of the animals that either avoid, or seek humans on the route. If you take horses or mules on the approach, they leave even more non-native remnants.
I do agree somewhat; for example, I'm somewhat depressed when I find cell phone repeater towers on remote peaks that are reached by a brutal scramble ... or by a helicopter. I think of the cell phone repeaters as religious shrines to iPhones and teenage text-messaging.
