IMMENSE FORESTS That HAVE TURN

An InsiGsA into the Mighty Operations ct
Nature One OF the Many Wonders Of
the Great Yellowstone National Park
Fossil Forest Ridge.
The Yellowstone National park is
called the wonderland of America, and
since the destruction of the New Zea
land geyser area it is perhaps entitled
to be called he wonderland of the
world, for within its limits the most
varied Of natures workings may be OBJ
served. Its hundreds of hot springs and
geysers, its PERCEPTIONS canyons and rush
ing cataracts, its snow capped mountain
peaks and mirrored lakes make it of
surprising interest. The lover OF nat
ural scenery may linger long over its
beauties and its wonders.
From the geological point Of view it
is also of great interest, for here may
be found rocks that range i'll age from
the most ancient of which we have any
knowledge to those in process of fOrma-
ton at the present moment. The su-
perheated waters of the hot springs and
geysers hold large amount of rock
making material in solution, which is
deposited about the openings of the
springs on the cooling of the waters, and
in this way building up mass of great
magnitude. These springs and geysers
are constantly breaking out in new
places, often on the borders or in the
forests CT living trees. The trees are
killed at once by the hot water, and on
becoming withered and dry begin soon
to take up the rockmaking solution by
which they are bathed, and thus to pass
into the fossil state.
Conditions similar to these, or at least
favorable to the preservation of fossil
forests, appear to have existed from o
remote time, for there is evidence to
show that the fossil forests were pre-
served before the most active of the hot
spring phenomena were inaugurated.
These fossil forests are located in the
northeastern corner of the Yellowstone
National park, at place known locally
as Amethyst mountain, or Fossil Forest
ridge. This is really a mountain some
ten miles long and rising nealry or quite
1000 feet above the general level of the
valley. If it were possible to cut Sec
ton down through this mountain, as

would be found succession of at least

this mountain, in the heart of which
may be read the story Of its origin. This

building, and consequently when the

their true nature, as they are covered

upright on the steep hillside, in the
