It was unfortunate that I was recovering from a cold. Firstly, because it was
a vacation and I don't like being sick on vacation, secondly, because we were
quickly descending into Death Valley and the pressure on my ears was getting
painful.
Holding my nose and mouth closed and gently pushing my breath against my ear
drums, I cleared my left ear, but it made the sensation
in my right ear even stranger and the pain was getting worse.
Against doctor's orders, I again forced my breath against my ear drums, and this
time my right ear cleared. At last I could hear, the pain was gone, and best
of all we were almost at sea level, 260 miles (416km) from the Pacific Ocean and more than
2,000 miles (3,200km)
from the Atlantic Ocean. Crossing Emigrant Pass we had reached an
elevation of 5318 feet (1621m), with the snow-covered peaks still rising another
5,731 feet (1747m) above us to the top of Telescope Peak at 11,049ft (3368m),
but now, just 45 minutes later, we were down to 5 feet (1.5m) below sea level.
Death Valley is a part of the magnificent landscape of Western North America,
called by geologists, basin and range. We were now in Death Valley, a very deep basin.
The mountains of the Sierra Nevada, Death Valley, and western Nevada
are huge parallel ranges separated by deep basins like Death Valley and the Owens
Valley. Together, these make up the basin and range landscape.
The forces of geology are evident here in Death Valley.
The alluvial fans which spread out from the mouths of all the canyons, are
formed as torrents of rain from violent local storms race down the canyons, gathering
rocks, dirt, and sand, which are carried downstream until the waters reach
the mouth of the canyon where they spread out, slow down, and drop their
heavy loads. Over millions of years, the mountains will be eroded and
and they will blend gradually into the valley, leaving small peaks in a sea
of almost flat alluvial fans.
Given enough time, the wind can also alter the landscape. It was the workings
of the wind that we first wanted to explore when we arrived at the ``town''
of Stovepipe Wells (5 feet (1.5m) below sea level). After pitching our tent at the
edge of the campground, we followed the main road to the sand dunes. I've
been told that first impressions are deceiving, and my first impression of the
sand dunes was all wrong. What I saw was a group of about 10 sand dunes, none
of the dunes larger than 5 feet high. I thought to myself, ``Oh great! The
tops of the sand dune are above sea level, big deal.'' Reality was a bit
different, however. We parked the car, and walked to those 5 foot high
sand dunes. Thirty minutes later we reached them, and we discovered that we
were in the midst of 60-80 foot (18-24m) high dunes!
The tracks of those who had come before us were visible, we could see where
a visitor had jumped off the steep edge of a dune and had landed softly
15 feet below. With our feet we could create rivers of sand that flowed
down the dunes. These mountains of sand are
the result of winds scouring the mountains, picking up grains of rock, and
carrying them to this location near Stovepipe Wells, where the shape of
the valley causes
the winds to swirl around, slow down and drop their grains of sand.
It has taken a mere 10,000 years to create these dunes!
Meanwhile, the sun was getting close to the ridges of the Cottonwood mountains to
the west, we sighed a peaceful sigh, and settled in to enjoy the colors
of sunset strike the dunes and the Funeral mountains to the east.
