The Norwegian eco-philosopher and mountaineer Peter Wessel Zapffe became increasingly disillusioned with our civilizations impact on the wild. As an old man he was asked if he would have climbed again given the chance. His reply was that he certainly would, if only to tear down the cairns he had helped build. He grew to dislike cairns, marked trails, signs etc., and argued that wild places should be allowed to remain exactly that - wild.
This photo is from a recent solo trip in gorgeous surroundings. For three days I saw no people, but many signs of human activity. Should they be there or should we strive for areas of nature with complete absence of mans presence? To be honest I am uncertain about my answer to this question, but emotionally I tend to agree with Zapffe.
