Among other factors, one of the natural features that affect and
are affected by changes in Earth’s climate is Glaciers.
Glaciers are frozen fresh-water reservoirs that change volume in
response to changes in temperature and snowfall.
Ice and snow also play an important role in the global energy
balance by reflecting from 60 to 90 percent of the solar radiation
they receive. On a scale more relevant to peoples' daily lives, the
seasonal melting of mountain glaciers contributes to summertime
river flow and to the ongoing sea-level rise.
In time scale, lakes and rivers stores fresh water for hundred or
few thousand of years as opposite to glaciers that could reach tens
of thousands of years but because the shorter glacier timescales
are comparable to human timescales, people get notice how glaciers
change, and these changes have obvious impacts on the human
environment. Many river systems depend on glacier melt, which
maintains the water supply through the summer. As glaciers shrink,
so does the frozen water supply they store. This is only one of the
reasons why it is important to measure how and understand why
glaciers change over time.
The given coordinates will lead you right at the middle of one
stream resulting of the Bossons Glacier meltdown. This stream is
feed by the high discharges processes of the glacier and is color
is due to the large volumes of sediment dissolved on it also
produced by Bossons erosion process
How can you log the
cache?
To claim this cache as found you
should send to this cache owner a message answering correctly the
following questions:
- At the given coordinates, on
left margin or this stream, you’ll find one wood bench made
of a trunk tree. What’s written on it?
- In your opinion what’s the
cause of the power of this stream, why?
- What’s the altitude showed
on your GPSr?
- Post with your log one picture
of you in the middle of the brigde “saying” bye-bye
with your hands.
If you believe you have
successfully completed this Earth Cache goals and has already sent
to this cache owner all the requirements as requested, Please, feel
free to log it as found. Later we will verify the requirements sent
and, if necessary, contact you in order to make the necessary
corrections to your log.
ATTENTION
It’s possible for winter the access to this
EarthCache became hard or impossible.
Please, always be aware of your safety, don’t go beyond your
limits.
