Tongass National Forest, National Geographic Magazine: Winter Morning On The Mendenhall River

Morning snow clings to tree branches along the Mendenhall River as it runs out of a lake at the base of the Mendenhall Glacier in the Juneau Icefield.

The placid pool of water is whitewater in warmer months when snow melts. Below the rapids where the river levels out, lush forests line the banks below the 7,000-foot mountains above the valley floor.
