As the malocca was but a short distance from the forest border, the tree-line would bring them close to its water frontage.
Higher and higher, above the tree-line now, the path went on, and there were signs of travel along it that worried me.
I have stood upon the thick tops of cedar trees on high places in the White mountains near the tree-line.
Above the tree-line no sound ascends but a faint vibration, the body of sound making itself felt in the silence.
In Colorado alone the Arctic-Alpine territory above the tree-line probably extends over five million or more acres.
