Different area. Different history. Different ethics.
For starters, a lot of IC routes don't have any alternate descent options.

Well...like the Gunks, many of these climbs are not done beyond half of a rope length. Alternative anchors other than bolts can be found (snipped cams, pitons, nuts, or for here, trees). Gang toproping. Legacy of staunchly traditional ground-up style. Visionary first ascents. Myopic modern climbers who rarely, if ever, go more than 100' off the ground. Even various forms of sandstone (okay, that's a stretch). All we need is some Mormons and an "era of good feelings."
