High Country Trail : Along the Continental Divide (Special Publications Series 16, No. 1)

Beautifully bound and illustrated coffee-table book. Out of an anvil-shaped mass of clouds, "rounded blooms erupted and turned frm purest white to mauve, then to pink, salmon, and orange. From the flattened underside of the anvil, lavender curtains of rain swept down to the green hills below, parted every few seconds by streaking touches of pastel lightning. The clouds, the colors, and the lightning were all reflected in the muted mirror of Heart Lake."
