Visual Impacts In Parks: Jet Contrails in Denali National Park

We can use simulated ranges of conditions to learn about visitor preferences.  Below, I show a series of images I developed to depict one potential aesthetic impact to wilderness recreation.  It is a nice, reliable, quantitative, repeatable technique for basing difficult and controversial management decisions on data.  Often used in people per viewscape/shed (PPV) and people at one time (PAOT) crowding measures. Not sure how it works for protecting your park, forest or refuge? Contact my research group. ZERO CONTRAILS VISIBLE   FEW CONTRAILS VISIBLE   SOME CONTRAILS VISIBLE   MORE CONTRAILS VISIBLE   MANY CONTRAILS VISIBLE   VERY MANY CONTRAILS VISIBLE   Pretty cool, huh?
