The five letters which provide the lyrics for the songs (adapted by the composer) were selected for their range of topics and sentiments. Some portray the wildlife in the mountains (“Glacier Birds...”). Others extol the beauty of the Sierra(“Mountain Glory,” “Yosemite Falls”). One expresses the whimsical/temperamental personality of the author (“Ice!”). And the final letter (“Sequoia”) speaks reverently of the great trees, in a language both naturalistic and sacred. They are the“greatest light in the woods, the greatest light in the world.”
