Route pages are supposed to list the difficulty in the upper left, and most people seem pretty good about designating the YDS class and grade. I would think a person would know right away if the climb were technical or not; it seems like we are proposing a lot of changes just to keep people from having to hit the back button. Much of the problem really stems from the SP search function. Perhaps it should be easy to search for mountain names and class; perhaps the difficulty category should be automatically bolded and in red.

Most of the routes are technical; one is a walk-up; several are scrambles. Often technical climbers are keen to know the non-technical routes as well, for descent purposes. Folks who climb the Whitney technical routes often descend the Mountaineer's route.
