After the windstorm we experienced here in the Keweenaw a few days back, I thought for sure the majority of the leaves would be off the trees, like these in the first shot from Doug Smith. On their way to the ground, some of them just happened to land right there in the park bench, like they were meant to be there.

But if you look up toward the sky, you'll see there are still some leaves to be found on the trees, like Michele Blau did in the second photo. There are a few bare looking branches up there, but plenty of color hanging on yet, too.

Not all the leaves that let go of the branch land on the ground. There are also the stray leaves that get caught up in unusual places. Jeremy Rowe found one that seems to be stuck on the side of a tree, peeking out from behind the bark and showing off the bright red coat of color it's wearing.

Again, nice Autumn pics. Just thought I'd mention, also, that 2-
day is Thanksgiving in Canada, and theirs is so colourful with its
Autumn leaves in so many parts of it. I'm sure the Keweenaw is
as colourful right now, especially since its geologically part of
the Canadian Shield.

Love the first picture, what a crisp clear shot of the leaves and bench! Great job Doug.

More good fall pictures today. It has been such a good year for colors.

Your just begging for a comment from me or the good Dr., aren't you??? ;-)

I had a cat that I would not let outside. One day I got a bushel basket and went outside and filled it uo with fall-dried leaves. The cat played with them and it was so funny to watch him. ;O)))

Tectonically speaking, is it shield, shelf, plate or…Tupperware?

By mickill mouse (Ram4) on Monday, October 13, 2008 - 04:26 pm:

in my posting the two letters 'uo' were suppose to be 'up'

Straight from the “Dictionary of Geologic Terms” by Bates and Jackson:

Shield: A large region of exposed basement rocks commonly with a very gentle convex surface, surrounded by sediment covered platforms. The rocks of virtually all shield areas are PreCambrian in age.

Shelf: A flat, projecting layer or ledge of rock, as on a slope. Or, a stable cratonic area that was periodically flooded by shallow marine waters and received a thin well winnowed cover of sediments.

Plate: A tortionally rigid thin segment of the earth’s lithosphere which may be assumed to move horizontally and adjoins other plates along zones of seismic activity.

Tupperware: Expensive plastic kitchenware, usually sold at posh get-togethers frequented by women.

And, I can add a couple more terms to this that could also describe the Canadian Shield or parts of it........

Craton: A part of the earth’s crust that has attained stability and has been little deformed for a long time. The term is restricted to continents and includes both shield and platform.

Platform: That part of a continent that is covered by flat lying or gently tilted sedimentary rocks that were consolidated during earlier deformations. The platform is part of the craton.

So, which term do we use to describe the Canadian Shield?? I tend to use the term “craton” to describe the North American core, and included in the craton are the Canadian “Shield” and the stable sedimentary “platform” resting on top. Oh, and to make matters even more complicated; the Keweenaw may be located within the Canadian Shield, but geologically it is not a part of the Shield (that'll open up a can of worms....).

Sorry for the long explanation on the photo of the day page; this is probably better suited for the Geology thread over on the various topics page. You may scold me, PastyCam powers-that-be........ ;-)

Mary says: Ok, that's it, Capt. Paul...50 lashes with a wet noodle for you! ;->

Sorry, if I caused anything. I was just explaining what I saw 1
time on a geological map of the northern hemisphere. The pics
are still nice.

All awesome photos!

By Margaret, Amarillo TX (Margaret) on Monday, October 13, 2008 - 07:59 pm:

No Mary, I needed all of those geologic terms so I come to Dr.'s Defence. Hooray for rocks.

By Capt. Paul (Eclogite) on Monday, October 13, 2008 - 09:46 pm:

No worries Thomas, I'm just having fun, as usual ;-)

But it is true that the Keweenaw is not geologically part of the Shield. I could go into more detail, but then Mary would lash me with that wet noodle some more.........

Indeed Margaret; HOORAY for rocks!!!!

So I don't start an argument, I found this article at Wikipedia.
However, since it's open to everyone 2 create or add 2 articles,
there could be mistakes in it:
