Massive columns have been wrenched from the
ceiling by this aqueous energy and lie prostrate on the floor; a
hollow column, forty feet high and thirty feet in diameter,
stands erect, but has been pierced by a tubular passage from top
to bottom in the same manner; a leaning column almost as large
has been undermined so as to resemble the leaning tower of Pisa;
these are only a few of the many wonderful forms of Nature's
architecture formed by no other tools than time and waterdrops.
We find no streams and true springs here as in Mammoth Cave, but
there are numerous basins of pellucid water, varying from one to
fifty feet in diameter, and from six to fifteen feet in depth.
Crystal Lake is a clear body of water surrounded by sparkling
stalactites. How long its waters must have waited to mirror
these lovely formations! They gleam and sparkle, forming an arch
of dazzling splendor; fit drapery for such a gem of water, which
shows again their marvelous beauty.
Here these waters have lain for countless ages with never a
breeze to ripple their surface. At Mammoth Cave the waters enter
through numerous domes and pits in cascades of great volume, and
are finally collected in River Hall where they form several
extensive lakes or rivers, which are connected with Green river
by two deep springs that appear under arches on its margin.
