Petrified Forest National Park (Ariz.)
Leaving the Headquarters area, where the Museum is located, the visitor
drives over a winding road, beautiful in its arid desert beauty, six or
seven miles to reach the Second Forest. Were it my privilege to name
this lovely section I should call it “The Coral Garden”. In this
“forest” are many logs encrusted with coral formation. Some of them have
broken apart and even the interiors are mossed with the coral, soft rose
in color. The ground is covered with tiny round stones, coral colored.
Here many logs are filled with crystals and the range of coloring found
in the chips strewn over the landscape is marvelous. Many pebbles bear
the impression of seashells, and deep in the heart of a section of
petrified log was found a fossilized mussel.

At one place in the First Forest a slender column of rock rises to the
height of thirty or forty feet. This is the Eagle Rock.]
There is little of the sandstone cap in this area, and the logs lie in
the blue-gray marl formation. Here we find larger trees in greater
masses than elsewhere. Many of the trees lie piled on top of others in
the coulees and small arroyos, carved out by wind and rain, during the
centuries since these logs first settled there. One big tree, near the
road, is mashed flat its entire length of perhaps ninety feet. Evidences
of bark are plain on this particular log, and where the limbs were torn
off, the grain of the wood is quite discernible. One could spend hours
in this area, spellbound with the beautiful sight.
The Natural Bridge
About eight miles from Headquarters, and three miles from the Second
Forest, is the most noted tree in the Monument, the Natural Bridge. This
sleeping giant lies where it was abandoned as a plaything by the waters
that carried it here. Each end is firmly embedded in the sandstone rock,
which was formerly the sand at the bottom of the sea. In the process of
erosion, which finally carried away all of the material above this log,
it ultimately came to lie on the surface of the ground. As the land
rises somewhat to the south of it, water gathered there with the big log
forming a natural dam. This water tended to soften the sandstone, and
after a period of time it forced its way through under the log. Soon
this became a free passage for the water, and resulted in the formation
of the gorge which the prostrate trunk spans today.
The Natural Bridge log is about four feet in thickness at the largest
point in sight. Part of the log is still encrusted with the sandstone
which wrapped it about, before wind and rain unshrouded it. The canyon
is twenty-five feet deep, and this one hundred and eleven foot log
measures forty-four feet between the points at which it rests on the
sides of the arroyo.
