Honestly, when everyone began clamoring for fat skis because they would allow them to track out powder more efficiently, ski faster, make more runs, skid turns, etc. not to mention enabling less skilled skiers to handle deep snow (ok, I mentioned it), I felt that was a breach of etiquette, a violation of my skiing traditions and customs.
It seems to me that the new style of large radius smeared turns vs. tradition of spooning short turns is a bigger threat to the preservation of untracked snow.
I'm a slow Telemarker on traditional skis. I'm not going to track out your mountain. If crossing my tracks is like dealing with a bunch of unfilled divots, maybe you should stick to golf.
On the rare occasions that I found myself on one of these traverses, I would sometimes start a higher traverse to get past slow traversers. Was that an ethical faux pas?
