A mountain is a living thing; it has an ecological balance, a process of evolution manifested in slow, subtle ways; but it is also subject to the ravages of human intervention. Filmed in the Canadian Rockies and in Garibaldi Park, this picture brings to the screen magnificent footage of mountain solitudes and the wildlife found there, of natural splendor in all its changing moods. The film carries the implicit warning that all this may pass away if people do not seek to preserve it.
