More on Yosemite
Dramatic
waterfalls, massive granite domes, and towering cliffs flank a broad,
glacially-carved valley to form the backdrop of one of America’s scenic
masterpieces. Nature’s perfection belies the staggering forces of fire
and ice that created the Yosemite. Cloaked more recently in alpine
meadows, pristine lakes and old-growth forests, Yosemite stands out as
a splendid jewel, even in its magnificent setting of California’s
Sierra Nevada mountains. Here the ancient and the new are woven
together in a tapestry of awe-inspiring beauty, one which has
captivated the hearts of writers, photographers, naturalists and
tourists for over a century.
"Every
rock in its walls seems to glow with life … as if into this one
mountain mansion Nature had gathered all its choicest treasures." –
John Muir

The Nature of Yosemite
By Bradford Glass
Yosemite
National Park straddles the Sierra Nevada mountain range about 4 hours
drive east of San Francisco. One of our nation’s earliest commitments
to preservation, "the Yosemite" was explored and perhaps made most
famous by John Muir, self-made, yet pre-eminent naturalist of the late
1800s. Ansel Adams focused public attention on Yosemite through his
world-renowned black-and-white images, evoking awe and wonder in those
who had never witnessed such natural beauty first-hand.
How
did Yosemite come to be? 500 million years ago, the land we know today
as Yosemite lay calmly at the bottom of an ancient sea. About 25
million years ago, the North American continental plate began moving
west, overriding the Pacific Ocean seafloor plate. Over the next 20
million years, the land warped upward and broke, leaving the ridge of
the Sierra (meaning saw-tooth) Nevada (meaning snow), with its gentle
western slope, and its steep, eastern face, as evidenced today.
Mountain snowmelt created streams that carved the land. Then for
thousands of years, continental glaciers scoured the land, widening and
deepening ancient streambeds, and scraping off all evidence of life.

Reflections of Creation

Crown Jewel

When
the glaciers receded some 10,000 years ago, Yosemite Valley lay still,
carved to the graceful "U" shape that is the signature of a glacier.
Where fire had produced the land itself, ice now gave it shape and
texture. Monolithic granite walls rise 4000 feet from the valley floor,
carved by glacial action into cliffs like El Capitan, sheer-faced domes
like Half Dome, and many multi-level waterfalls like Yosemite Falls,
Vernal, Bridalveil and Nevada falls. Many waterfalls drop from their
own, smaller, glacially carved river valleys, now hanging high above
the Merced River below. The time since glacial retreat has been kind to
Yosemite. Known more for its scenic beauty than its wildlife, Yosemite
is carpeted in verdant wildflower-filled meadows; old growth forest of
Douglas fir, sequoia, cedar; mountain lakes, rivers and streams.
If
the grandeur of this scene weren’t already enough, it is perhaps the
variety of moods in Yosemite that are the most captivating. Mist rising
from the Merced River at dawn; a nighttime snow in the valley giving
way to a crystal-clear sunrise; that last ray of sunlight painting an
orange stripe across El Capitan or down the veil of a waterfall;
constantly changing shadows as the sun traces its daily course; the
breathtaking silence of a winter morning. Yosemite is a place of
feeling; it’s a place for all of our senses; and it’s a place that
takes us beyond our senses. It’s a place where we can be totally
present in this moment, connecting us with the timeless, and with the
universal -- our own place of peace. |
