@tsarstepan,
A lot of that kind of landscape is what we do to reclaim and clean up mining sites. When acid water mixes with the minerals in the lode, the results are usually some toxic soup that would kill any aniumals that drink the water.
Id be willing to bet that that stream has apH of at least 2 (or lower) and no trees will grow in the valley.
Thanks Tsar, Im gonna be up in Maine and NH in Oct and Nov,its an easy trip and Ill have to follow up on this show, the Burtynsky looks really interesting
