Is it the Drake Passage through the Horn?

Or just a plain of fi-jord?

Not Drake Passage, and while it is a fjord, obviously not so plain.
Quite a distance from Montana.

JimBob, this feature is named after a location in Wales, so should be a snap with your ancestry.

Over 9 miles in length with towering peaks grazing the sky.  Also one of the wettest places, in terms of precipitation, on earth.  Made famous by Rudyard Kipling.

After working since 6 AM and doing a little tidying up around here this P< I am too tired to google "the works of Rudyard Kipling" and do anything else. Please someone pick up this sputtering tourch from my failing hand? Please!

catches torch and promptly burns her fingers.....


ayyyyyyyyyyyy...... sorry, no idea... but my goodness IT IS GORGEOUS !!!!



Your hint made this too simple.  Finally googled "1268 hills" and found several thousand hits on the Chocolate Hills in Bohol.
DOH! 
Looks like a beautiful place- have you ever visited?
From what I could gather, the hills are composed of limestone- likely old reef deposits, that eroded from rainwaters to form the conical shaped hills.  Interesting that there is no karst formation (caves) in the area.  Will try to find more research on their formation.

Nope - sadly I have not seen them myself but it's firmly on my list of 100 places to visit before I die. Would love to hear more about how they possible came about so if you do find out a bit more do let me know.  :)

Captain Courageous was too long ago - New Zealand on the South Isle - BUT - Middle Earth did it - Milford Sound.

Didn't know how many on this forum would remember Captain Courageous??  Milford Sound it is.

Milford Sound is a fjord.  "Fjord:A glaciated valley flooded by the sea to form a long, narrow, steep-walled inlet".  During ice ages, ocean levels drop and glaciers can erode valleys below present day sea levels.  As the glaciers melt and sea levels rise, these glacial valleys are flooded, producing some of the most spectacular scenery on earth.

oh wait, I have to figure out the picture thing.




.. ok well I am stoopid.. I can't upload them because they are too big and I can't figure out how to HTML them.. so they remain clickable links (I hope) :)

Check Your PMS JnA.

These links should have more to them.. should end in JPG OR GIF

Like this:

Try again and put them between these imaging brackets:  Hit the square box above the fist

smiley.. that is imaging bracuts, then copy your link and paste it between those

bracuts.. do this with both separate links!

JnA

NO, you are not butting in. Glad you are here amongst us
These don't look natural. Are they?

If they are they are jointing features - the result of fracturing of the rocks. But square jointing such as this is very rare.

And, like Karen, I'd like to know where were the pictures were take.

Hi JimBob

yes, they are natural, at least that is what the sign at the location said.

"The fractures are in three sets, one set runs almost north, another east north east, and a third discontinuous set north north west. These last two sets produce the tiled appearance. The flatness of the pavement is due to initial erosion by waves carrying sand and gravel and nearer to the cliff, to chemical action by sea water. The rocks which absorb sea water during high tide dry out during low tide causing salt crystals to grow and disintegrate the rocks - a process which produces shallow basins'."


 The placard notes that the information has been provided by the Geology Department of the University of Tasmania.

So that gives away the location :)

On the way to the old penal colony of Port Arthur is a place called Eaglehawk Neck. These tessellations can be found there.

Interesting aren't they?

Awesome jointing.  As my erstwhile colleage pointed out, square jointing is rare- much more common to see jointing at 60 and 120.
Thanks for sharing the photos.

Gee Bass, If you know about the 60 and 120 sets, perhaps you could venture a suggestion about the question of the week, HUH?

Yes JnA, these are indeed rare and very interesting to see. Once Bass, or even a geology student (it's simple stuff Bass) answers the "question of the week" all will become clear as to why apparently square jointing is so rare.

WHOA!  Someone seems to have there panties tied in knots ;)

Sorry JB, for not getting around to all these posts earlier- besides being feeble-minded, I just spent the past 4 days at my "other" job, teaching powder lessons to skiers at our local ski area.  We've had close to 4 feet of prime, light powder over the past week- so when opportunity knocks...

Will answer QOTW asap.

We must keep up appearances you know. There are certain standards we of the Illuminati must keep up or they will consider us as extraneous. It is a matter of class, you know. And you know how superior these Brits feel themselves. I am sure you understand.

c00l photos JnA. Thanks for sharing  :)



... and...?... so..? ... come on....


Why is square jointing so rare?

I'm dying of curiosity here and yes, I've checked the Qotw and no, I have not found what I supposedly should have found, e.g. an answer to this burning questions of why?

And no, I'm not British - so there!  :P

will try to explain this better when I have more time- but the basic answer is that joints (or fractures) develop in response to strain in the rock.  Imagine taking a circle and squishing it from one side (that is, adding strain).  The circle beomes an ellipse.  Fracture sets develop at an angle to maximum shortening (the short axis of the ellipse) and are rotated due to elongation with more strain.



I'm leaving for another extended bit of employment, but will try to get back to this as soon as possible.
