A couple years ago I was up on the Easton Glacier doing crevasse rescue practice. All day we breathed fumes of snowmobilers going up and down the glacier around us. In the afternoon an electrical storm developed, prompting us to haul ass out of there. We quickly packed up camp and prepared for the last few hours of the day after an already long day... and well three of us had "nature's call" at about the same time. We proceeded to find separate spots to drop trou facing away from the Railroad Grade and towards the open glacier terminus. Almost on cue two snowmobilers passed nearby us, as we saluted them with a row of bare asses and dropping brown, corn-fed toilet trout (and yes, we blue bagged them out of there).
