Look at a range from a summit or across the valley and the slopes break into spurs, ravines and ridgelines that drain off every peak, near and far.

Look out past the valley and the land runs on to 49 to 57 km, where it used to stop about 17 km out, so distant ranges stand on the horizon. High summits in late summer are bare rock, with snow in streaks down the north-facing ravines.

Rivers bend in rounded curves, and beside a river the banks fall away gently instead of dropping into 12 m dirt walls. Shrubs, rocks and logs on a lake’s far bank now reflect as themselves, lit by the light bouncing around them, instead of as hard black shapes.
