Requirements:
E-mail answers to the following
questions...
1. N34 47.630 W087
37.636:
What is the
height and width of the cave
opening?
How wide is the waterfall
cascade?
2. N34 47.634 W087 37.622:
What is the
height and width of the rock window?
3. N34 47.643 W087 37.587:
What is the
height and width of the falls.
What is the type of
waterfall?
4.Choose one of the three areas listed
and have your picture taken with your GPS.
Picture requirement:
My intentions are to have you post your picture with your choice of
feature in the background. If you refuse to post your face in the
picture, then each log must have a unique picture for each log.
Tilting the picture with a photo program will not be acceptable for
unique. Group photos must reference who's picture you are in
otherwise. A unique picture must be included with every log if you
are not in the picture. .
Remember that I will delete your log if you post a find saying you
will upload the picture or send answers at a later time. Please use
the "write a note" feature.
Do not post answers with your log. Send
answers before posting your find to avoid log deletion. Any logs
without a photo and answers being sent will be deleted without
notification.
Cave
A cave is a natural opening in the ground
extending beyond the zone of light and large enough to permit the
entry of man. Occurring in a wide variety of rock types and caused
by widely differing geological processes, caves range in size from
single small rooms to interconnecting passages many miles long. The
scientific study of caves is called speleology (from the Greek
words spelaion for cave and logos for study). It is a composite
science based on geology, hydrology, biology, and archeology, and
thus holds special interest for earth scientists of the U.S.
Geological Survey.
Waterfall
Classification
Types of waterfalls are based on how the
water falls or passes through it's course, how much water is
flowing, the surface beneath it and the geological processes that
created it (geomorphology). These all together form a waterfall's
unique shape, it's fingerprint so to speak.
Block / Sheet: Water from a wide
river or stream drops over a ledge forming what appears to be a
"sheet" of water. Ideally, it is not broken into segments at high
water and it is observably wider than tall.
Cascade: Cascade is a commonly used
term when referring to waterfalls and rightly so. The term
"cascade" comes from the Italian word "cascada" which actually
means "waterfall". A cascade type waterfall is defined by the
surface beneath it. It is one of the most common as the surface
beneath it is irregular and encompasses the falls not classified
elsewhere. It is generally water that flows down in small steps or
stages. Multi-Cascading is more than one cascade in a
row.
Cataract: Another word for waterfall
but usually one that is large, very powerful and rushes down with
force usually occurring on a river.
Chute: A violent section of water that
is forced through a narrow passage due to cliff walls or large
rocks. Depending on the descent angle, they may be classified as
rapids not a waterfall. Very common in canyons where the water is
wall-to-wall.
Classical: Similar to Block, water
drops over a ledge but is close to equal in width and
height.
Combination: Many waterfalls are a
combination of more than one type of falls. At Paulina Creek Falls,
you will find curtain, slide, segmented, and scree /
talus.
Curtain: Similar to Block and
Classical, water drops over a ledge but is taller than wide but not
a Ribbon.
Dry / Historic: This type of falls no
longer exists with water flowing over it. It is referenced here as
some of these historical falls were very magnificent in their time.
Dry Falls in Washington is one of these type and in it's day it was
over 3 miles wide and had a huge flow of water, the unique thing
about this falls was that it only flowed when the glacier lifted up
to release the water.
Fan: Water falls through a relatively
narrow crest and spreads out and becomes wider as it
descends.
Frozen: These falls can be of any
other type and it must have ice as a part of the falls. They are
spectacular as the ice formations are just as unique as the falls
themselves. If the temperature is just right, punchbowl falls will
often form a cone in the bowl of water.
Horsetail: Water descends down
remaining in contact with the surface most of the
time.
Keyhole / Slot: Water pushes through a
narrow area before falling. A keyhole is a special slot as it has a
rounded part at the bottom of the slot resembling the old fashioned
keyholes. Some times the water has forced (eroded) out a part of
the rock causing an actual hole water falls from.
Ledge: A geological formation that
influences shape of waterfall. It is a cliff that is relatively
flat with some width at the top and is vertical or almost vertical.
Angel Falls and Niagara Falls are great examples of a ledge. The
following shapes / types often result from a ledge.
Overhanging Ledge: Another geological
formation that influences shape of waterfall. It is a cliff that
the water has eroded under it causing an obvious overhang resulting
in the water free falling to the surface below.
Parallel / Twin: Parallel falls happen
when falls are side-by-side and fall similar to each other. There
can be two or more falls and can be from the same watercourse (also
see Segmented falls) or from more than one watercourse. Twin falls
are also side-by-side but do not have to be similar in type. Triple
and more falls exist as well.
Plunge / Vertical: Water descends
vertically without contact with the surface.
Punchbowl: Water falls through a
constricted area and descends down into a pool of water. The water
"punches" through and falls into a "bowl".
Ribbon: Water descends in a narrow
strip significantly taller than it is wide.
Segmented: Pieces of land segment the
river (same watercourse) causing the water to fall in sections. Not
to be mistaken with different watercourses forming different
waterfalls side-by-side as in Parallel / Twin falls.
Scree / Talus: Water flowing over a
chaotic mix of rock debris on a slope usually found at the base of
a cliff or steep incline. Scree is usually the rocks that are
smaller than a softball and talus is larger than a
softball.
Slide: Water glides over a single slab
of rock maintaining smooth continuous contact.
Tiered / Staircase / Multi-Stepped: Separate waterfalls falling consecutively and in close
proximity so generally they can be seen together. Any type of falls
can be tiered.
Veil: Water falls over rocks (usually
large rocks) creating a thin layer of water that just barely covers
it's surface.
Arches
General Description:
Window or arches are natural holes that
form along cracks and weak spots in thin walls of rock called
"fins." By convention these holes must be at least 3 feet in
diameter in two perpendicular directions to earn the name arch or
window. An imprecise distinction is often made between bridges and
arches in terms of the processes that form them. It's important to
remember that gravity is the key factor in either case.
Nevertheless, the distinction is that bridges are carved by flowing
water, whereas arches can be carved by everything else except
flowing water. Indeed, in very few circumstances is it possible to
say that flowing water had zero contribution in the development of
one of these natural holes. Therefore, geologists often prefer the
term window to collectively describe any large hole in a
rock.
I love this area
and thought it needed an earthcache and wanted to give something
back to all the cachers who have placed caches in the area and
added to our geocaching adventures. Hope you
enjoy!!!
