Meatloaf Moutonnée

Accretionary Wedge #30 is a geololgical bake sale. Now most folks have interpreted this in the traditional way and made baked goods in the cake family. I, however, decided to indulge my carivorous cravings by baking a meatloaf in the shape of a roche moutonnée.

I give you Meatloaf Moutonnée:

Where on (Google) Earth #243?

Once I realized it was up I made relatively quick work of Ryan Brown‘s WoGE #242 of the Tasman Glacier on the South Island of New Zealand, which he kindly posted without a Schott Rule invocation. The shadows were the dead giveaway. The vast majority of alpine glaciers are located in the northern hemisphere, so when I noted the sun casting shadows on the south side of horns and aretes it only took a quick search of Patagonia before I headed over to the New Zealand Alps for the win.

I’ve enjoyed the quick pace of the last month or so of Google Earth posts. For WoGE #243 I’m choosing a relatively large area with a bit of coastline. Normally this would merit a Schott Rule invocation, but I have a sneaky feeling this one may be a bit tougher to find than it first appears, so I’m electing not to invoke it. I may, of course, be wrong, in which case the winner will post a locality (latitude and longitude) and description of the geology of the area seen below before the electrons on this post have a chance to dry. Time will tell…

GigaPanning Geology – Fine Gigapixel Conference Retrospective

Longtime readers will know I’ve been very involved with the GigaPan project for a couple of years now. I’ve been a Fine Science Fellow since the beginning of my involvement with GigaPanning in the Fall of 2007, and I’ve previously helped to train new Fine Science Fellows on the GigaPan at workshops at in Estes Park, CO (May 2008) and Pittsburgh, PA (May 2009). A bit over a month ago I had the opportunity to serve as a workshop co-chair for the first Fine International Conference on Gigapixel Imaging for Science, also held in Pittsburgh. Since returning I’ve been a bit too wrapped up in teaching to blog about it, but grades were submitted at noon today, so I’m finally free to catch up on some of the blogging that I’ve been putting off for far too long.

I won’t burden you with a full rundown of the conference, but if you’re interested you can find more information at the full conference website or perhaps you’d prefer to peruse the abstracts of the submitted papers. In addition to co-chairing the workshops with fellow Fine Fellow Richard Palmer, I presented or co-presented two formal workshops and one informal one. I’m embedding below the YouTube video of my workshop entitled “GigaPanning Geology” below. You can also see what I had to say about creating Anaglyph (3D) GigaPans on another YouTube video. And there are even more conference videos here.

One of the great things about this conference for me was the number of new geologists who are getting involved in GigaPanning. Callan Bentley, who blogs at Mountain Beltway, attended this conference as a brand new Fine Science Fellow, meaning he got a brand new GigaPan robot just a day before the conference. You can find Callan’s GigaPans here. John Van Hoesen, who blogs at Geologic Musings in the Taconic Mountains, already owned his own GigaPan and has been using it for a couple of months. You can see John’s GigaPans here. Finally, Laura Guertin didn’t own a GigaPan at the time (she does now) but she was interested in seeing how she might use one for geology. The four of us got together during a break between talks to record a brief (13 minute) podcast about what we all hoped to do to apply GigaPan technology to geology. Have a listen!

This is by no means the last you’ll hear from me about GigaPanning Geology. It’s going to come up again in short order at the upcoming GSA Penrose Conference “Google Earth: Visualizing the Possibilities for Geoscience Education and Research”. But for now I’ll leave you with a GigaPan of Pittsburgh, PA from Mount Washington that I shot while at the Conference. If you’ve got red/blue anaglyph glasses you can also see this one in 3D!

Where on (Google) Earth #240?

Wooohoo! This is the tenth WoGE of the month, making this the first time since Septermber & October of 2007 that we’ve had back to back months with double digit WoGEs. And I should point out that this is not just the usual suspects. We’ve seen plenty of new winners mixed in with the veterans. Congratulations one and all!

Having found French PhD student Rom T.’s very first WoGE, I’m going to stick with the coastal theme. To mix things up a bit I’ll offer up an oblique view of this very interesting coastline. But to be honest, I’m choosing this view for the beautiful wave refraction visible in the foreground as much as anything else. I figure the oblique view and relatively small area should offset the fact that coastlines are usually easy to recognize, so I’ll keep things moving along by not invoking the Schott Rule. The goal, as always, is to identify the location of the image below (latitude and longitude) and to describe as much as you can about its geology – answer in the comments. First person to succeed on both points has the honor of hosting WoGE #241 on their geoblog.

If this view proves too challenging I’ll provide a map view in a few days.

Where on (Google) Earth #235?

In honor of the world’s largest(?) ever gathering of Geobloggers and Geotweeps this evening at the AGU Social Media Soirée I hereby present Where on (Google) Earth #235? for your entertainment. Most of you already know that to win the challenge you need to find the latitude and longitude of the image below and describe the geology of the area to the best of your ability. Post your answers in the comments and if you’re the first to identify both (as I was for WoGE #234) you’ll have the honor of hosting the next WoGE on your own social media platform.

Where on (Google) Earth #235.

No Schott Rule, since I’m a little late posting this one. We’ve gotta keep up the pace if we’re going to reach double digit WoGEs for the second month in a row. Let the chaos commence!

Update: Now that its been found I figured I’d add a GigaPan view of the area that I shot last summer:

Where on (Google) Earth #232?

It seems like every time Where on (Google) Earth gets stuck in the mud (volcanoes) I’m the one who gets to pull it out. This was true back on WoGE #69 and its still true today on WoGE #231. What is it about these petroleum geologists, that they keep dragging WoGE back through the mud (volcanoes)? ;-)

Despite the brief pause for mud, WoGE has really been rolling lately. In fact, November 2010 was the first month with double digit WoGE postings since October 2008. Curiously, there haven’t been back to back months with double digit WoGE posts since September-October 2007.

Recently I’ve posted a couple of WoGE locations that were harder to find but had interesting geology. Today, however, I’m in the mood for one of those spots that has exquisitely beautiful geologic imagery, even though there shouldn’t be too much mystery in finding it or describing the geologic features. As a consequence, I’m going to invoke the Schott Rule (please wait an hour for each WoGE Win you’ve got before answering). Though it’s a small area, I don’t think this one shouldn’t be too hard to find, so it’s especially aimed at those of you who may be new to the game. If you’re playing for the first time, the goal is to identify the location of the image below (latitude and longitude) and to describe its geology – answer in the comments. First person to succeed on both points has the honor of hosting WoGE #233 on their geoblog.

Where on (Google) Earth #214?

New geoblogger Ryan Brown over at Glacial Till didn’t take long to find WoGE #212, and since he was kind enough not to put a Schott Rule on it I was able to return the favor and quickly identify the lovely barchan dunefield encroaching on the estuary of the meandering Rio Preguiças that he chose for WoGE #213.

For WoGE #214 I’ve selected a rather large area (by WoGE standards), so I expect it won’t be too hard to locate. Thus, I will choose to invoke the Schott Rule (please wait an hour for each WoGE Win you’ve got before answering). The real challenge in this one will be encapsulating the very interesting geologic story contained in this otherwise unassuming Google Earth image. I’m looking for more detail than just a one line geologic description (but don’t feel compelled to write a thesis before identifying the location and claiming the right to post WoGE #215). One or two of you may even have field photos from this region (please share!) if you’ve been lucky enough to visit it on research or a field trip…

A Tale of Two Slides (Told Tardily)

Rather than rushing to post WoGE #214 (look for it tomorrow), I want to take a couple of minutes to post a couple of landslide GigaPans that I had originally intended to post back in September to go with that month’s Landslide theme on Pathological Geomorphology.

The two slides that I want to highlight happened about 34 years apart and are located just outside the boundaries of two of America’s most visited national parks.

On or about June 23, 1925 about 38 million cubic meters of rocks and debris slid northward off of Sheep Mountain and into the valley of the Gros Ventre River, forming an impoundment that now holds back Lower Slide Lake. Almost two years later a portion of this landslide dam failed and the resulting flood wiped out the town of Kelly, Wyoming killing six people. In this GigaPan you can see the upper scar of the slide on Sheep Mountain and some of the debris that is still only sparsely vegetated over 80 years later.

On August 17, 1959 the M7.5 Hebgen Lake Earthquake triggered a massive landslide that blocked the drainage of the Madison River and formed the modern day Quake Lake. This 360 degree panorama is shot from atop the landslide deposit. To the south one can see the landslide scar on the facing ridge. All around the camera location are the blocks of bedrock displaced during the slide – some that ran up the hill opposite the landslide scar are the size of small houses.

Driving back towards Yellowstone, I paused for one last view back across Quake Lake…

Where on (Google) Earth #212?

Brian Romans of Clastic Detritus may be on the road, but I’m gonna do my best to summon his spirit on this first day of Earth Science Week 2010. Brian, of course, was responsible for originating Where on (Google) Earth, two blog incarnations and many moons ago. Brian also traditionally brings us a weekly Seafloor Sunday post, and lest we all go into deep withdrawal on both of these counts, I propose to kill two birds with one stone.

Furthermore, Where on (Google) Earth?s have also been a fairly reliable way for me to get my own blogging juices flowing, and since WoGE #211 was solved but has lain fallow for almost two months now, I’m exercising my authority as keeper of the official list of WoGE Winners to revive and resuscitate one of the Geoblogosphere‘s longest running institutions. Since it’s been so long, it’s worth reminding everyone that the object of Where on (Google) Earth is to identify the locality of the image below (latitude and longitude will generally suffice), but also to explain the geological significance of the site. Since very early on it has been the tradition for the winner (first person to correctly identify the location and geologic significance of this WoGE) to host the next challenge on their own geoblog. If the winner has no geoblog, then they are hereby responsible for starting a brand new geoblog of their own – it’s really not that hard, just ask if you need assistance. (Seriously, don’t bother playing if you’re not willing to shoulder the responsibility of hosting the next challenge. We don’t need to see this valuable institution disappear into oblivion again.) The winner is further responsible for posting a link to the next challenge in the comments of the previous one as soon as the new challenge is posted. In this way we are able to maintain a chain of links to the most current incarnation of WoGE.

I think WoGE #212 will be relatively easy to locate, so I’m choosing to invoke the Schott Rule – wait an hour for each WoGE you’ve won before answering, please. Post time: 10/10/10, 23:10 Central Daylight Time (USA) – 11 Oct 2010, 4:10 GMT. (The Schott Rule is invoked at the discretion of the geoblogger who posts the new WoGE. Easy challenges generally merit a Schott Rule invocation, whereas more challenging ones generally do not. The main purpose of the Schott Rule is to allow new competitors a fair chance to participate by keeping previous winners from dominating the game.)

And now, I’m off to sleep with the fishes!

In the Delivery Room

When considered in the context of Earth’s geologic history, the range of geological experiences I’ve had the opportunity to actually experience firsthand are generally so mundane that none could be considered “important”. Certainly no one geological experience I’ve had stands out in my mind as singularly “important” – at least not yet.

And yet, choose I must, because September is nearly done and I’ve missed yet another Accretionary Wedge deadline. So, though I’m interpreting this topic a bit differently than many of my peers, my selection is, on some level, a trite and jaded one.

So many geological processes that we witness at Earth’s surface are destructive (e.g., weathering, erosion, mass wasting, etc.) but how often do we experience Mother Earth renewing herself? I submit that it is not often, yet when considered in the context of the rock cycle, it is of fundamental importance. How much less exciting would geology be on a planet that had long since ceased to be active? Thus I choose for my most “important” geological experience being present at the birth of a rock.
