Echoes of the Past ???
There is no greater puzzle in the world than the world itself.
Between 9-to-10 million years ago, a volcanic eruption brought lava over the
sandy beach of an ancient Arizona lake.
The heat contained within the lava drew water from beneath the sand up into
points. These formations, called
fumaroles, served as chimneys to discharge steam and volcanic gases.
A large amount of calcite was deposited within the fumaroles.
Today, the 10-to-12 foot high "fossilized fumaroles" give the impression
to unwary visitors that they are actually walking on the surface
of the moon.
