[Video description: A uniformed park ranger walks along an unpaved trail surrounded by redwood trees. There is a lot of variety in the size, width and height of the hundred of trees he walks under. The ranger initially climbs some switchbacks and passes several stumps, fallen trees and many kinds of ferns. Eventually the ranger reaches the apex of the trail and begins descending as the sounds of a waterfall are heard.
