When you think about it, they are primarily interested in people who live and work in the harshest environment. When we recreate in such areas, we are the briefest of visitors, who have only minor knowledge, compared to residents.
Norman Clyde might have been one who crossed that boundary in our Sierra. George Durkee would be a modern equivalent. It seems that such people are constantly disappointed in what us visitors do and think about the places in which we are brief visitors.
