Pathological Geomorphology

Pathological Geomorphology http://geopathology.posterous.com Hard to define, but we all know it when we see it. posterous.com Sun, 25 Sep 2011 19:16:51 -0700 The River That Looks Like a Signature http://feedproxy.google.com/~r/pathologicalgeology/~3/1plBWi8v09s/the-river-that-looks-like-a-signature http://geopathology.posterous.com/the-river-that-looks-like-a-signature <p> I haven't posted on here in a long time ... I don't know why, I love this site. I've actually been using it for my class. Maybe this will get me posting again.<p />At the recommendation of @bedform on Twitter (sedimentologist / geomorphologist Dan Parsons) I was checking out <b>Rio Bermejo</b>, a tributary to Rio Parana, in Paraguay earlier tonight. This is a truly pathological river from head to toe. But one of the oddest parts of this river is this stretch that, to me, looks like someone's really sloppy signature. Or, maybe this is the autograph of Rio Bermejo itself.<p /> Awesome.<p />Images from GoogleEarth --- lat/long: -25.716860°, -60.015136°<br /> <p><div class='p_embed p_image_embed'> <a href="http://posterous.com/getfile/files.posterous.com/geopathology/Oyc3zYyT53LXU9NljsJiUoAz4Kn9VPJtZkyanAX9gFGSs1WhkX9cfIZE9Q9L/signature-river-1.jpg"><img alt="Signature-river-1" height="259" src="http://posterous.com/getfile/files.posterous.com/geopathology/6sB0KjsNQHqZGcCnIWJXtAJ30GPhlt0iYVzxbKsQ5A3QromdJbt9J6XUfCzf/signature-river-1.jpg.scaled.500.jpg" width="500" /></a> <a href="http://posterous.com/getfile/files.posterous.com/geopathology/iMwtc2EVnJumSvJMqmZyBCtSNP2cjkg0oytIVb0F8Oxbyw0NNQgYrjpjH98b/signature-river-2.jpg.scaled.1000.jpg"><img alt="Signature-river-2" height="293" src="http://posterous.com/getfile/files.posterous.com/geopathology/A9IllBsLJRq4cdjW6wpphLWQqJAf69TsUYSmU2Qsd9slRlBLvXbigSALfJMJ/signature-river-2.jpg.scaled.500.jpg" width="500" /></a> <div class='p_see_full_gallery'><a href="http://geopathology.posterous.com/the-river-that-looks-like-a-signature">See the full gallery on Posterous</a></div> </div> </p> </p> <p><a href="http://geopathology.posterous.com/the-river-that-looks-like-a-signature">Permalink</a> | <a href="http://geopathology.posterous.com/the-river-that-looks-like-a-signature#comment">Leave a comment  »</a> </p><img src="http://feeds.feedburner.com/~r/pathologicalgeology/~4/1plBWi8v09s" height="1" width="1"/> http://files.posterous.com/user_profile_pics/1500669/avatar.jpg http://posterous.com/users/5fiNjV40Hap3 Brian Romans clasticdetritus Brian Romans http://geopathology.posterous.com/the-river-that-looks-like-a-signature Thu, 25 Aug 2011 16:56:50 -0700 What this tired site needs is a little more Madagascar...you up to it? http://feedproxy.google.com/~r/pathologicalgeology/~3/sk8-7r6UPDQ/what-this-tired-site-needs-is-a-little-more-m http://geopathology.posterous.com/what-this-tired-site-needs-is-a-little-more-m <p> <p> </p> <p><div class='p_embed p_image_embed'> <a href="http://posterous.com/getfile/files.posterous.com/geopathology/NHlO8NyBZOirBvab5NxEtuwelGTFHIfnSEXHIwSpjCBZFZ5w6xWJn52wkxhE/8-25-2011_4-52-19_PM.png"><img alt="8-25-2011_4-52-19_pm" height="446" src="http://posterous.com/getfile/files.posterous.com/geopathology/LpIYPqfnG1fgsFOWbeeK70GTSNxa9wXPFqfpjSwnIFrJyUlJQoR2AdVwfKUt/8-25-2011_4-52-19_PM.png.scaled.500.jpg" width="500" /></a> </div> </p><p><div class='p_embed p_file_embed'> <a href="http://geopathology.posterous.com/what-this-tired-site-needs-is-a-little-more-m"><img alt="" src="http://posterous.com/images/filetypes/unknown.png" /></a> <div class='p_embed_description'> <strong>Madagascar_01.kml</strong> <a href="http://posterous.com/getfile/files.posterous.com/geopathology/AblyR2aCdNDxzHAKqVBokq4CR4I3bFfISZiqoeNUl4TywGbGluetVLFI7sBn/Madagascar_01.kml">Download this file</a> </div> </div> </p> </p> <p><a href="http://geopathology.posterous.com/what-this-tired-site-needs-is-a-little-more-m">Permalink</a> | <a href="http://geopathology.posterous.com/what-this-tired-site-needs-is-a-little-more-m#comment">Leave a comment  »</a> </p><img src="http://feeds.feedburner.com/~r/pathologicalgeology/~4/sk8-7r6UPDQ" height="1" width="1"/> http://files.posterous.com/user_profile_pics/1493258/2011_07_02_1373.JPG http://posterous.com/users/eHuEdPl3vr Kyle House Dr. Jerque Kyle House http://geopathology.posterous.com/what-this-tired-site-needs-is-a-little-more-m Sat, 30 Jul 2011 16:51:00 -0700 Pathological Oregon scenery.... http://feedproxy.google.com/~r/pathologicalgeology/~3/xAzeyusxu9A/pathological-oregon-scenery http://geopathology.posterous.com/pathological-oregon-scenery <p> <p>Near Plush, Oregon: Some wacky wetlands with complex array of pluvial lake shorelines, lunettes, blowouts, dune fields, and much more water than usual. <p /> Also, a couple of hyge landslides with impressive hummocky runouts;

While breccia pipes have been in the headlines as of late due to the increased demand of Uranium, the sinkholes near Holbrook are interesting in their own way in part because their formation is ongoing. True breccia pipes in northern AZ form through the upward propogation of cavern collapse in the Redwall limestone. Salt karst or sinkhole formation near Holbrook is the result of salt and gypsum dissolution within the Supai Formation. Like breccia pipes, dissolution and collapse in the subsurface propogates upwards resulting in a sinkhole at the surface. Most sinkhole features in the Holbrook Basin are concentrated along the Holbrook Anticline (actually a monocline). Flexure along this feature is related to dissolution of deep salt beds. In addition to sinkholes, numerous tension cracks have formed due to the bending of rigid bedrock overlying zones of dissolution along the monocline. Overall, up to 500 sinkholes and fissures have been recognized between Springerville and Winslow (Neal, 1998).</p> <p>A large cluster of sinkholes lies ~25 miles SSW of Holbrook (10 miles NNW of Snowflake) is known simply as "<a href="http://www.flashearth.com/?lat=34.563398&lon=-110.238829&z=14.9&r=0&src=msa">The Sinks</a>". Dozens of sinkholes pockmark the landscape, some as large as 500 feet across. There are 2 main fields of sinkholes beginning just north of Hwy 277 west of Snowflake.</p> <p><div class='p_embed p_image_embed'> <a href="http://posterous.com/getfile/files.posterous.com/temp-2011-06-16/yhkzkcytmiecGolulwEpouiAIJwdhHhAxcJpBGntmHmcFBvDgEwrlDyhdGHu/Fullscreen_capture_6162011_41012_PM.bmp.scaled1000.jpg"><img alt="Fullscreen_capture_6162011_41012_pm" height="348" src="http://posterous.com/getfile/files.posterous.com/temp-2011-06-16/yhkzkcytmiecGolulwEpouiAIJwdhHhAxcJpBGntmHmcFBvDgEwrlDyhdGHu/Fullscreen_capture_6162011_41012_PM.bmp.scaled500.jpg" width="500" /></a> </div> The holes in the <a href="http://www.flashearth.com/?lat=34.793829&lon=-110.588756&z=15.6&r=0&src=yh">McCauley Sinks</a> locale below are up to 580 feet across. The pattern of sinkhole formation here approximates two concentric arcs. Perhaps this is a result of a larger scale of subsidence manifested by numerous smaller features. In addition to round sinkholes, numerous tension cracks due to subsidence are found near the sinkholes.

How many sinkholes or tension cracks lie just below the surface? The Arizona Department of Water Resources has recently documented at least one area which has potential for new sinkhole formation.

The scale of these features closely matches existing sinkholes in the area. It seems likely that we are witnessing the incipient stages of sinkhole formation in this area.</p> <p><div class='p_embed p_image_embed'> <a href="http://posterous.com/getfile/files.posterous.com/temp-2011-06-16/aqHovmeeEjIqqsdosplogxCloCtGcqzFwhaCGHelxphfpufgvzkweFhhkdFE/Holbrook_Sinks-1.jpg.scaled1000.jpg"><img alt="Holbrook_sinks-1" height="652" src="http://posterous.com/getfile/files.posterous.com/temp-2011-06-16/aqHovmeeEjIqqsdosplogxCloCtGcqzFwhaCGHelxphfpufgvzkweFhhkdFE/Holbrook_Sinks-1.jpg.scaled500.jpg" width="500" /></a> </div> <br />Information from this post was largely derived from <span style="font-family: Trebuchet MS, Trebuchet, Verdana, sans-serif;">AZGS Open File Report 02-07, "A Review and Bibiography of Karst Features of the Colorado Plateau, Arizona" by Ray Harris.

The Red River of the North is at major flood stage, <a href="http://all-geo.org/highlyallochthonous/2011/04/why-does-the-red-river-of-the-north-have-so-many-floods/">again</a>, and the Minnesota River <a href="http://www.wctrib.com/event/article/id/80191/group/homepage/">flood crest </a>is moving downstream. It's a pretty frequent occurrence in both of these river systems, and in part, flooding is a legacy of the glacial history of the area. The Red River flows to the north along the lake bed of Glacial Lake Agassiz, <a href="http://all-geo.org/highlyallochthonous/2011/04/why-does-the-red-river-of-the-north-have-so-many-floods/">which is pathologically flat</a>. The Minnesota River flows to the south along the channel of the <a href="http://mrbdc.wrc.mnsu.edu/mnbasin/fact_sheets/valley_formation.html">Glacial River Warren</a>, which was gouged out of the landscape by water draining from Lake Agassiz.</p> <p>14,000 years ago there was direct connection between what is now the Red River basin and the Minnesota River basin. Today, there's a continental divide - with the Red flowing toward Hudson Bay and the Minnesota flowing toward the Mississippi and Gulf of Mexico. But what a strange continental divide it is - for it runs through the former outlet of Lake Agassiz, in what is now known as Brown's Valley or <a href="https://secure.wikimedia.org/wikipedia/en/wiki/Traverse_Gap">the Traverse Gap</a>. This divide is not so much a high point in the landscape, but a just-not-quite-as-low area. The little community of Brown's Valley sits between Lake Traverse (flows to the North, forming the headwaters of the Red) and Big Stone Lake (flows to the south, forming the headwaters of the Minnesota).</p> <p>Here's what it looks like on Google Earth. Note that I've set the terrain to 3x vertical exaggeration, so that you have some hope of seeing the subtle topography of this area.<div class='p_embed p_image_embed'> <a href="http://posterous.com/getfile/files.posterous.com/temp-2011-04-06/ixBcautnpIzmmyrGICazqkmcDfeCaEkHktkkFCbpdkvybwprBqgBwcultDpp/CropperCapture12.jpg.scaled1000.jpg"><img alt="Croppercapture12" height="398" src="http://posterous.com/getfile/files.posterous.com/temp-2011-04-06/ixBcautnpIzmmyrGICazqkmcDfeCaEkHktkkFCbpdkvybwprBqgBwcultDpp/CropperCapture12.jpg.scaled500.jpg" width="500" /></a> </div> </p> <p>This is a very, very cool oblique photo <a href="https://secure.wikimedia.org/wikipedia/en/wiki/File:Browns_Valley_flood_07.jpg">from Wikipedia</a>.

So I have 'gone all alluvial on you' here, lately. Sorry. But today I agreed to review a paper about alluvial fan flooding in Iran and decided to go and look around. I don't expect to ever make it to Iran, but the desert geomorphology (and the structural geology, and the salt glaciers, etc., etc.) found there is absolutely amazing. Nice that Google Earth can allow us to check it out.
