A couple of months ago I did a post about Skyline Caverns -- it is located in Front Royal, Virginia, about 90 minutes
from downtown D.C. It's a great trip at any given time of the year due to the
constant 54-degree temperatures in the cavern.
Over the years I've visited a few different cavern sites and
each one is unique in its own way. There are a few things that are special
and unique about Skyline Caverns, probably the most being it possesses anthodites, a rare
formation that occurs in caves. Anthodites are also referred to as the
"Orchids of the Mineral Kingdom."
Defined, the U.S. Geological Survey (USGS),
states, "Aragonite, a calcium carbonate mineral similar to calcite but not
as common, often occurs in intricate needles known as anthodites."
Discovered in the 1930s by Dr. Walter Amos and his crew, the
anthodites at Skyline Caverns were totally accidental. On the tour visitors
learn one of the workers had gotten a shovel stuck in the mud and it took many
men to help pull it out. As the men loosened the shovel, an explosion-like
force occurred. What they found was astonishing.

Remarkably, the crew had stumbled upon an air vacuum. By
yanking the shovel out, that seal had been broken. While common in outer space,
it is a rare occurrence on Earth. However, breaking the seal did prevent the anthodites from
growing any further. The ones found by Amos and his crew are now eternally
preserved in four stages of growth. Really neat to see, especially if you are fascinated by this kind of thing.

Truly exquisite in nature, for the most part scientists are
puzzled as to how they form. Although, the mystery is said to add to their
beauty. Skyline is one of the few places in the world where the public can see
them. Seeing the beautiful
handiwork of Mother Nature up close and realizing the secrets she holds up is a memorable experience.
