Geologically: the view here shows Permian sediments to Tertiary (I will always be using that word) volcanics to Quaternary (there I go again...so old school) debris on the valley floors.
Literally: the view here is long. No biology to interfere with the view.
Environmentally, the area is so fragile, that we can see how a little degradation can end up a problem for decades or even centuries.
Can we as a society take a long view. I wonder sometimes.
