Fine specimens may be found any night at the foot of
the Upper Yosemite Fall, glowing gloriously amid the gloomy shadows and
thundering waters, whenever there is plenty of moonlight and spray. Even
the secondary bow is at times distinctly visible.
The best point from which to observe them is on Fern Ledge. For some
time after moonrise, at time of high water, the arc has a span of about
five hundred feet, and is set upright; one end planted in the boiling
spray at the bottom, the other in the edge of the fall, creeping lower,
of course, and becoming less upright as the moon rises higher. This
grand arc of color, glowing in mild, shapely beauty in so weird and huge
a chamber of night shadows, and amid the rush and roar and tumultuous
dashing of this thunder-voiced fall, is one of the most impressive and
most cheering of all the blessed mountain evangels.
Smaller bows may be seen in the gorge on the plateau between the Upper
and Lower Falls. Once toward midnight, after spending a few hours with
the wild beauty of the Upper Fall, I sauntered along the edge of the
gorge, looking in here and there, wherever the footing felt safe, to see
what I could learn of the night aspects of the smaller falls that dwell
there. And down in an exceedingly black, pit-like portion of the gorge,
at the foot of the highest of the intermediate falls, into which the
moonbeams were pouring through a narrow opening, I saw a well-defined
spray-bow, beautifully distinct in colors, spanning the pit from side
to side, while pure white foam-waves beneath the beautiful bow were
constantly springing up out of the dark into the moonlight like dancing
ghosts.
