Taken 2.7 straight-line km / 1.7 mi west-northwest of Tsoukalades. I was either on the current main road from Thebes to Delphi, or on a precursor that also passed this vantagepoint.<br /> <br /> The strange quadrangle of bright objects at bottom right is not a squadron of low-flying UFOs, but reflective insulators on a transmission-line pylon that is otherwise lost in the gloom.</i> <br /> <br /> It’s good to have finally exited my mythical locale of Elephino, and to be back in a place that I can actually pinpoint on Google Earth.<br /> <br /> As noted in previous posts in this album, the weather during my approach to Mount Parnassus was photographically miserable, with plenty of rain, clots of mist drifting overhead, and the sun breaking through briefly at all the wrong times. When that happened, as it did here, the water droplets in the air turned the snow on the summits into a milky glare that obscured the massif’s true immensity.<br /> <br /> But details were still visible down on the shaded low ground. When I scrutinized this photo recently, I became intrigued by one of those details: a hill just to the left of center, directly over the darkened ridge in the foreground. It was a dead ringer for a <i>cuesta</i>, a type of landform that has much exercised me in <a href="https://www.flickr.com/photos/196253572@N05/albums/72177720324135897">another series</a>. <br /> <br /> A cuesta is a ridge or hill, asymmetrical in cross-section, that has for its front and back slopes one that is gentle and another that is a steep and clifflike scarp. This is due to its being made of sedimentary strata that have been tilted up from their original horizontal orientation. As these layers erode, they produce the profile just described.<br /> <br /> So is the hill in this photo a cuesta? It certainly seems to have a steeper left-hand face, albeit stepped and indented, and a shallower right-hand side. I would have identified it as a cuesta gladly, had I not already learned that this whole area has been tectonically crunched, smooshed, faulted, overthrust, and fubarized to a remarkable degree. The simple slanting of some beds due to one act of compression seemed unlikely in a place that resists parsimonious explanations.<br /> <br /> Fortunately, I then came across a wonderfully annotated photograph of this very hill in the source cited below. It indicates that it is made up of three different rock units, as defined in that article. All are sedimentary, so the cuesta hypothesis so far sounds plausible. But there’s a big complication.<br /> <br /> The problem lies in the sequence of those rock units. As I explain this problem, please do not blame me for the arcane terminology used to identify them. Remember that it’s not sporting to shoot the messenger.<br /> <br /> This is the problematic sequence:<br /> <br /> - The hill’s top section is the slanting, recessed portion of carbonate rock. Its scarp is bluish-gray and it has a narrow, dark-green mantle of trees. My source identifies it as the <b>First Mesoautochthonous Cycle</b>. Got that?<br /> <br /> - The next section of the leaning layer cake is the very similar mass of vegetation-covered and bluish-gray carbonates with a separate scarp that projects out farther. It’s the <b>Second Mesoautochthonous Cycle</b>. That was predictable.<br /> <br /> - And below that is a heavily vegetated slope that extends to the base. This is the <b>Pelagonian Flysch</b>. You can’t see this here due to all the plant cover, but it is a reddish-ocher tint that can be better appreciated in <a href="https://www.flickr.com/photos/196253572@N05/54855616031/in/dateposted-public">the Part 26 photo</a>. And it’s a clastic rather than chemically precipitated sedimentary type. <br /> <br /> The weird thing is that the First Mesoautochthonous Cycle, Cretaceous in age, is the oldest of the bunch. The Second Mesoautochthonous Cycle is Cretaceous too, but its fossil content proves that it was deposited after the First. And the Pelagonian Flysch is younger still; it dates to the Paleocene and Eocene. So we have an inversion of the usual order, with older beds sitting on top of younger ones. How did that happen?<br /> <br /> The answer is that the whole assemblage has been completely flipped upside down. In a realm of wholesale continental compression—here read the continent of Africa plowing into the underside of Eurasia—such topsy-turvy relationships involving overturned folds, later eroded into hills and other landforms, are by no means rare. In fact, inverted stratigraphic sequences can also be found in such places as the northern flank of Mount Helicon and at the Delphi archaeological site. As I have taken pains to point out in earlier posts.<br /> <br /> One other interesting aspect about the hill in question is that it also contains a reverse fault, another good indicator of crustal compression. It lies at the contact of the Second Cycle and the Flysch. So the hill’s upper, carbonate part has been pushed up some distance over the clastic strata. The evolution of the Boeotian landscape can never be described by just one event or process. <br /> <br /> But then I’m beginning to think that’s true of every place on this hyperactive planet. <br /> <br /> <u>My Main Source for This Essay</u><br /> <br /> - Nirta, Giuseppe, Giovanna Moratti, Luigi Piccardi, Domenico Montanari, Nicolaos Carras, Rita Catanzariti, Marco Chiari, and Marta Marcucci. “From Obduction to Continental Collision: New Data from Central Greece.” <i>Geological Magazine</i> 155:2 (2018), 377–421. <br /> <br /> <br /> <b>To see the other photos and descriptions in this series, visit my <a href="https://www.flickr.com/photos/196253572@N05/albums/72177720323847479/"><i>Geology (Architectural &amp; Otherwise) of the Earth's Center</i> album</a>.</b></p> <p><a href="https://www.flickr.com/people/26747591@N08/">markdbaynham</a> posted a photo:</p> <p><a href="https://www.flickr.com/photos/26747591@N08/54910786590/" title="Pontianou (Portianos) Military Cemetery ( Limnos - NE Aegean - Greece) (Panasonic Lumix S1 &amp; Lumix S 24-60mm f2.8 Zoom) (1 of 1)"><img src="https://live.staticflickr.com/65535/54910786590_d2cf65384d_m.jpg" width="240" height="135" alt="Pontianou (Portianos) Military Cemetery ( Limnos - NE Aegean - Greece) (Panasonic Lumix S1 &amp; Lumix S 24-60mm f2.8 Zoom) (1 of 1)" /></a></p> <p><a href="https://www.flickr.com/people/26747591@N08/">markdbaynham</a> posted a photo:</p> <p><a href="https://www.flickr.com/photos/26747591@N08/54910473836/" title="Pontianou (Portianos) Military Cemetery ( Limnos - NE Aegean - Greece) (BW) (Panasonic Lumix S1 &amp; Lumix S 24-60mm f2.8 Zoom) (1 of 1)"><img src="https://live.staticflickr.com/65535/54910473836_991136b8df_m.jpg" width="240" height="135" alt="Pontianou (Portianos) Military Cemetery ( Limnos - NE Aegean - Greece) (BW) (Panasonic Lumix S1 &amp; Lumix S 24-60mm f2.8 Zoom) (1 of 1)" /></a></p> <p><a href="https://www.flickr.com/people/26747591@N08/">markdbaynham</a> posted a photo:</p> <p><a href="https://www.flickr.com/photos/26747591@N08/54909604122/" title="Pontianou (Portianos) Military Cemetery ( Limnos - NE Aegean - Greece) (Panasonic S1 &amp; Lumix S 24-60mm f2.8 Zoom) (1 of 1)"><img src="https://live.staticflickr.com/65535/54909604122_5a937ab84f_m.jpg" width="240" height="135" alt="Pontianou (Portianos) Military Cemetery ( Limnos - NE Aegean - Greece) (Panasonic S1 &amp; Lumix S 24-60mm f2.8 Zoom) (1 of 1)" /></a></p> <p><a href="https://www.flickr.com/people/26747591@N08/">markdbaynham</a> posted a photo:</p> <p><a href="https://www.flickr.com/photos/26747591@N08/54910676328/" title="Weekly Sunday Morning Flag Raising Ceremony (Myrina Town Harbour - Limnos - NE Aegean - Greece) Panasonic S1 &amp; Sigma 65mm F2 Prime Lens (1 of 1)"><img src="https://live.staticflickr.com/65535/54910676328_cd03433cb1_m.jpg" width="240" height="240" alt="Weekly Sunday Morning Flag Raising Ceremony (Myrina Town Harbour - Limnos - NE Aegean - Greece) Panasonic S1 &amp; Sigma 65mm F2 Prime Lens (1 of 1)" /></a></p> <p><a href="https://www.flickr.com/people/26747591@N08/">markdbaynham</a> posted a photo:</p> <p><a href="https://www.flickr.com/photos/26747591@N08/54910708619/" title="Harbour Front at Sunset (Myrina Town - Limnos - NE Aegean - Greece) Panasonic S1 &amp; Sigma iSeries 65mm F2 Prime Lens"><img src="https://live.staticflickr.com/65535/54910708619_354e74019d_m.jpg" width="240" height="135" alt="Harbour Front at Sunset (Myrina Town - Limnos - NE Aegean - Greece) Panasonic S1 &amp; Sigma iSeries 65mm F2 Prime Lens" /></a></p> <p><a href="https://www.flickr.com/people/imthessalonikis/">imthessalonikis</a> posted a photo:</p> <p><a href="https://www.flickr.com/photos/imthessalonikis/54910715780/" title="IMG_2859"><img src="https://live.staticflickr.com/65535/54910715780_a6b6952047_m.jpg" width="240" height="135" alt="IMG_2859" /></a></p> <p><a href="https://www.flickr.com/people/imthessalonikis/">imthessalonikis</a> posted a photo:</p> <p><a href="https://www.flickr.com/photos/imthessalonikis/54910716165/" title="IMG_2896"><img src="https://live.staticflickr.com/65535/54910716165_a99252dc37_m.jpg" width="240" height="135" alt="IMG_2896" /></a></p> <p><a href="https://www.flickr.com/people/imthessalonikis/">imthessalonikis</a> posted a photo:</p> <p><a href="https://www.flickr.com/photos/imthessalonikis/54910412826/" title="IMG_3108"><img src="https://live.staticflickr.com/65535/54910412826_ab254f0865_m.jpg" width="240" height="135" alt="IMG_3108" /></a></p>
