Explanation:
Scheduled to illuminate the landscape
throughout the night tomorrow, October's
bright Full Moon will also be
called the Harvest Moon.
Traditionally, the Harvest Moon is the Full Moon closest to the
autumnal equinox.
But in this vacation snapshot, the Full Moon could be called
the "Old Faith-Full Moon".
Taken on September 4, the picture combines
the regularly occurring lunar phase with
Old Faithful Geyser in
Yellowstone National Park,
named for its dependable erruptions.
Shining on the well-known geyser's
towering pillar from behind,
the moonlight creates an eerie halo surrounding convoluted shapes.
Faithfully, the Full Moon itself is bright enough to be seen
through the dense swirling steam near the top.
