The wonders of the Grand Canyon cannot be adequately
represented in symbols of speech, nor by speech itself. The
resources of the visual arts are taxed beyond their powers in
attempting to portray its phenomenal beauty. Language and
illustration combined must fail. The elements that unite to make
the Grand Canyon the most sublime spectacle in nature are
many and exceedingly diverse. The giant forms, which result from
the sculpture of tempests through ages too long for man to
compute, are wrought into endless details. To describe these
forms would be a task equal in magnitude to that of describing
the stars in the sky or the abundant beauties of the forest with its
traceries of foliage presented by oak and pine and poplar, by
beech and linden and hawthorn, by tulip and lily and rose, by fern
and moss and lichen. Besides the elements of form, there are
elements of color. The rainbow is not more replete with hues. But
form and color do not exhaust all the divine qualities of the Grand
Canyon. It is the land of music. The river thunders in perpetual
roar, swelling in floods of music when the storm rains play upon
the rocks, and fading away in soft and low murmurs when the
infinite blue of the sky is unveiled. With the melody of the great
tide rising and falling, swelling and vanishing forever, other
melodies are heard in the gorges of the lateral canyons, while the
waters plunge in the rapids among the rocks or leap in great
cataracts. Thus, the Grand Canyon is a land of song. Mountains
of music swell in the rivers, hills of music billow in the creeks, and
meadows of music murmur in the rills that ripple over the rocks.
Altogether it is a symphony of diverse melodies. All this is the
music of waters. The adamant foundations of the earth have.
