Potholes
No not the kind that cause havoc on your car's steering.
I'm talking about Mother Natures Potholes.
Ok, Coman have you gone crazy??
Nope, read on.
What is a Pothole, and How are they formed?
Pothole (or kettle-hole) is also a term for
a formation in rivers caused by a
whirlpool eroding a hole into rock.
The abrasion is mainly caused by the circular motion of small
sediments such as small stones in the river. The interiors of
potholes tend to be smooth and regular.
Potholes are formed by erosion.
Pebbles and sand carried by the river are swirled around on
the river bed.
This action erodes the rock on the river bed forming
potholes.
Over time, they may widen and join with other potholes to form
larger potholes.
At ground Zero there are many "Potholes"
From very tiny to larger ones.
To log this Earth Cache you must do the following
Answer the following Questions and E-mail the answers to me
through my Geocaching Profile.
1) Using a tape measure or a really good guess what is the size
of
the 2 larger potholes at GZ L,W and Depth
2) with in 20 meters of GZ are there more or less then 100
potholes
(Count Carefully,some are very small)
3) On your way into GZ you should have passed a
Water Survey of Canada Benchmark
What is the approximate distance from it to the 2
larger potholes at GZ?
4) Why are most of the Potholes near the East side of this
area?
5) Post a Picture of your GPS with the
Water Survey of Canada Benchmark
with your log
(Optional, but appreciated)
