An excellant example of a Scree Field.
May not be available during the winter months: mid-October through late-May.
So there we were, traveling the countryside when we came
around a bend and saw this excellant example of a scree
field. Now you may ask, what is a scree field? Well have a
seat and let me tell you a tale. Way back in the long ago
Sven E-Peoplesen was traveling the mountains and saw this
exact scree field. Well, it wasn't called a scree field at that time, Sven
kind of coined that term from the old Norse word for landslide:
skriða, but since this wasn't Norway he called it scree.
Now scree are rocks and boulders that have been broken
off a mountain due to the freeze / thaw process. You see the
water trickles down into the cracks and holes in the rock.
During the winter the water freezes, and since water
expands at about 9% when frozen, the pressure forces the
crack in the rocks to expand, sometimes forcing the rock to
break off. So in official sounding language: formation of
scree or talus deposits results from physical and chemical
weathering and erosional processes acting on a rock face.
The predominant processes that degrade a rock slope
depend largely on the regional climate (temperature, amount
of rainfall, etc.).
That said scree also occurs because of man made issues
like the scree field around the base of Mount Rushmore,
that scree field was caused by the craving of the monument itself.
Okay, to claim this cache this is what I need, the answer the following:
1. What is the altitude at the coordinates?
2. Post a picture of the sign at the coordinates.
3. What is the percentage water expands when frozen?
Remember, BEFORE you may log and claim this earthcache as a find, you must first email us your anwers to the questions. DO NOT put your answers in your log posting!
