This photo, taken on Amchitka during WWII shows the rolling tundra.   While Amchitka may be treeless, the plants can still be tall.  If you see the dark square-ish patch in the lower right hand corner, that's the entrance to a dugout cave.  There is a man standing next to it, waist deep in summer foliage.
