Ok , I am of course biased. Maybe to some , ski descents are the purest form? Maybe for Trask, The trolling of this site is the purest form?
When I think of the purest form, I go back to Mummery and Tillman and the like, leading (soloing) the first difficult summits in the Alps. I have presented this to people from this site, and have added and changed things with the chart. Your suggestions are appreciated on this work in progress.
