Reminiscence
July 28, 2019
On that hot day in late July I finally
got back into the woods, starting with a visit to Cottonwood Pond.
Pond??
Simply the fact that I ever called it a
“pond” brings back memories.
When it happened – when that big
Cottonwood fell and left a deep bowl that filled with water – I had
hopes. I thought that maybe it would harbor life and go through
evolutionary stages resulting in a big bowl of water teeming with a
variety of aquatic plants and animals. It would be almost like a
natural aquarium, but with direct influences from the environment all
around it.
Well, I was right about the influences
of the surrounding environment, though that didn't turn out the way I
had thought (hoped?) it would. Instead, periods of heavy water flow
(especially pronounced during the first half of this year) have
pushed tons of sediment through the area. Some was pushed beyond the
banks of the “pond”, but some settled, especially where chunks of
fallen wood (from the Cottonwood's rotting roots) functioned as small
dams.
There were very interesting changes to
watch, though, as the area changed. Various types of plants appeared,
and animal life. Last year, and especially this year, I could see
that the deer were finally coming into the Cottonwood Pond area.
As I roamed the area on this day, I
looked back in time, remembering how it once was. Everything changes
while forces, through time, act upon them. But, like someone looking
at photos of one's progeny as a small child, or thinking of how the
old neighborhood was “back in the day”, I still wanted to
reminisce about the earlier Cottonwood Pond, the one hardly anyone
else got to see.
Here's a sketch I did in April of 2014
(a year after starting this blog). Here we are standing by the Creek
(bottom of sketch), looking at the bottom of the Cottonwood's Root
Ball, or root mass (which is the semi-circular structure near the top
of the drawing), and the bowl of water below it. So much has changed.
You can refer back to this drawing as we move along through the
reminiscence, as well as to the next drawing that will appear.
On the right you can see the “Barkless
Log” (probably a former Sugar Maple tree) stretching across toward
the Root Ball. Below it the Inlet developed, a way for water to enter
the main pond. Above it you can see the “Bent Blue Beech”
(American Hornbeam, Muscle Tree). Stretching across the Creek, along
the pond's edge, and then under the Barkless Log is the Very Rotten
Log. Below the Root Ball, to the left, you see one Mud Pile
developing.
Here's another view:
The Main Pond
It's hard to believe now, but I used to
do depth measurements of this! The bowl of water was fairly
consistent, with definite edges. The deepest part was the side closer
to the Inlet, where rushing water entered and gouged at the pond's
bottom.
Those were the days! It was even hard
for me to reach to that deepest spot. So, I devised my
Handy-Dandy-Depth-Measuring Device from an old broom handle, garden
twine, a heavy, flattish rock, and a red twist-tie. The first
measurement was taken on March 27, 2013. The deepest part measured 21
½” deep. And, there was a dead Fox Squirrel in the pond.

The Main Pond on July 28, 2019, looking
toward the Inlet – just mud on this day. The pond bed was dotted
with tiny (but tall) Crawdad chimneys, worm trails, and tracks from
my dog, Babette.
After that, I started taking water
samples and also dipping into the water and mud to see what animal
life I could find. I found a number of different macroorganisms
(tadpoles, frogs, snails, leeches, an aquatic “earthworm”, and an
aquatic larvae of a type of moth, water beetles, for example) as well
as fascinating microorganisms (blue-green algae, Daphia, midge
larvae, etc.). You can read all about it (and see some photos and
drawings) by searching the Cottonwood Pond blog for titles containing
words like “Sampling”, “Little Critters”, and “Scoping”.
The same view, but on a map I drew in 2015:
This map shows the deep part of the
pond, Mud Pile #1, Mud Pile #2, the Cove, and one sapling growing
from the Root Ball.
First, Mud Pile #1 started forming from
soil that had fallen from the Root Ball. Then, Mud Pile #2 started to
form at the southeast end. Plants grew on the Mud Piles, diversifying
the habitat. Animals of various sizes burrowed into the Root Ball,
and spiders stretched webs across burrow entrances. The habitat
became even more diverse. A Sugar Maple had taken root at the top
edge of the Root Ball and quickly grew into a sapling. One day, my
friend Cherie and I found a Northern Water Snake wrapped around it.

The Root Ball, Mud Pile, and Main Pond from the north
The bottom side of the Root Ball
The Cove
One day I noticed a little opening that
had developed at the bottom of the Root Ball, starting near the
southeast end. On another day, I detected a spot of light! The action
of water from both sides of the Root Ball eventually carved a hole
all the way through, which I dubbed The Cove. One day, I watched a
Green Frog hop through! So, then I knew the Cove had become a
wildlife thru-way. When there was water in it, I imagined a tiny boat
going through, its riders seeing the Cove as a huge cavern opening,
revealing a new world on the other side.
Over time I observed the Cove enlarge
across the bottom. But, as more soil fell from the Root Ball the Mud
Piles grew taller and wider, then joined in the middle, obliterating
the Cove.

The Old Logs
Back in the day, the Very Rotten Log
was not yet so rotten. I could use it for things. It still looked
like a definite log (or, fallen tree), round and complete, though it
was covered with moss in many places. I set things on top of it and
leaned things against it when I did depth measurements, water
sampling, and scoops to look for animal life. It held my side pack,
sampling jars, and lenses. The Handy-Dandy-Depth-Measuring Device and
my notebook and pen had a place to lean.
I used the Very Rotten Log to traverse
the Creek to Cottonwood Pond. It held my weight without complaint
back then and lent its support. I did not have to find a good-enough
spot to jump the Creek.
Then came a time when the Very Rotten
Log became so spongy that it squished up water with each of my
careful steps. Later, I could feel it give under each step, and I
quit using it to cross over. In time it became thinner, wetter,
mossier, and supported more fungi that were helping to break down its
wood. Finally, it broke. The broken-off section was pushed to the
Creek side by rushing water as jagged Very Rotten Log ends stuck out
above the Creek shore on either side.
Eventually, too, the ground-resting
parts of the Very Rotten Log sunk into the soil, becoming part of it.
Sections became indistinguishable from the ground. Then, only vague
remnants, and memories of what was.

Somewhere in the middle of what was the Very Rotten Log - just pieces!

Where is it??
And the Bent Blue Beech (BBB on the
map) that was rooted on one side of the Creek.
When the great Cottonwood fell, it
caught this young, strong American Hornbeam (Blue Beech, Muscle Tree)
and bent it over, arching it over the Inlet. When standing on the
southeast end of Cottonwood Pond, I loved how this framed the whole
scene with its gnarly Root Ball and shining water. On the other side
of the Root Ball, the narrower end of the BBB stretched out and up,
over the ground.
Over time I watched the little
“suckers” grow from near the BBB sapling's base. Shelf mushrooms
grew on the arched wood. It became evident that the once supple
arched trunk had died and become brittle, and the quickly-growing
suckers were taking its place. Then, one day, the arch snapped, and
the Bent Blue Beech became the Broken Blue Beech. It still framed the
view for awhile, but then gradually the two sections, one succumbing
to gravity, pulled farther apart.

many-pronged, grows on top of the Cottonwood Trunk

Then there's …
The Cottonwood Trunk
or, another Old Log, but a grand one.
What a grand thing it was, back in the
day, still covered with it rough furrows of bark! The top half of the
Trunk stretched (as of this date, it still does) across the low area
and up the adjacent slope. At the top of the slope is a large,
double-trunk Red Oak tree. The top of the Cottonwood, when it fell,
wedged into the “v” between the Red Oak trunks.
Looking up the Trunk toward the Red Oak
On top of the slope - the top end of the Cottonwood tree in the "v" of the Red Oak
Mosses and lichens grew between bark
fissures, just as when the tree was standing. As the Trunk faded from
Life, though, fungi also took over. For a few years I found clusters
of large Oyster mushrooms growing from the Trunk, with their
dramatic, wavy caps and gills. If only I had been sure of what they
were then, I could have feasted on them!
Bark pieces started falling off along
most of the Trunk, revealing mycelia of fungi and fine roots of
plants that were starting to grow from rotted wood. Various small
wildlife traversed the smooth and bumpy sections, or lived in them.
In winter there were Squirrel tracks on the snow-covered Trunk.
There came a time when all of the bark
had fallen, leaving only some near the base to remind me how the
whole tree had looked. Mosses and fungi then started from cracks in
the wood and spread over the Trunk's surface. Some fallen bark pieces
were swept away by rushing water. The rest stayed below the Trunk,
turning to soil.
Moss and dark fungus
Then the bark fell from the Trunk's
base, leaving me with only memories.
The base of the Cottonwood Trunk, and "little pond" as a puddle, on July 28, 2019
Where the Trunk stretches over the low
area, just before the slope, there is a spot that always has had the
largest opening. I used to simply duck my head to go through to the
other side, near the Swampy Spot. Now there is much less space. To
get through, I would need to crouch and waddle like a duck, or crawl
through like a Raccoon. I don't know why this has happened, but I
have two theories, and I believe it can be one of these, or a
combination of both:
- The top of the tree has disintegrated and settled further into the “v” of the Red Oak, making the rest of the Trunk sink further toward the ground along the slop and over the low area.
- So much water has moved down Temporary Creek #1, through the Swampy Spot, and under the Trunk (then flowing to “little pond” and Temporary Creek #2) that it has deposited a great deal of silt, thickening the soil layer below and decreasing the space. Flooding would also add to this.
There are so many more places in the
Cottonwood Pond area I could reminisce about – the Seep, the Creek,
the Barkless Log, the Inlet, the Isthmus, the Swampy Spot, etc. - but
these are the aspects that bring back the most memories.
There is constant change, of course,
and abruptly at times. I look forward to the changes here at
Cottonwood Pond. But, I can't help reliving the way it was during
those earlier times.

I wonder if your last blog will be titled The Death of Cottonwood Pond?
