It’s more than a year that I haven’t solved a WoGE (Where on GoogleEarth?), but I came across Ron’s latest quiz and found it quite fast to my own surprise. He had a very unusual location – a seamount off the island of Oahu that turned out to be no volcano but part of a giant landslide instead. Beautiful spot, great story.
Now I have the honour of hosting WoGE #414, and here it is: more
I came across this great initiative after Richard Styron sent the announcement via the Geotectonics mailing list. He’s currently maintaining these projects. The idea is to compile all available data on active structures in the Himalaya using the GitHub infrastructure (basically a collaborative platform for programming) . Everyone can join and help compiling active faults in this region. The data is then available to everyone for free in different data formats. The same thing is currently happening for the Andes region, too! more
Matthew’s WoGE #364 took us far out to South Georgia and on the Neumayer glacier – a phantastic example of rapid glacier retreat due to changing sea water temperatures. As you might immediately see from my image, I want to take you to a more comfortable area, but with some nice geology, too. Here’s the quiz: more
Rhett Howell’s WoGE #359 was located in Utah – the Death Hollow is a beautiful example of Navajo sandstone, bordered by two deep canyons and with a very interesting joint system. The site is situated on a huge monocline and part of the Grand Staircase-Escalante National Monument. So now it’s my turn again to host the next one. Here’s WoGE#360: more
A very strange story happened in OC California some days ago (thanks @EricFielding for pointing me to that). A woman suffered serious burns because some rocks her kids found at a beach combusted spontaneously in her pocket. Immediately, a discussion started on twitter. What kind of rocks could that be? Hydrocarbon-bearing sediments? Coal? Phosphor? There have been some accidents with phosphor from World War II weapons that was washed upon the shore of the Baltic Sea. People confused it with amber. However, this is unlikely at California beaches. Mysterious rocks… more
Matthew’s WoGE #345 looked pretty much like an ocean shoreline, but it turned out to be Lake Khanka located at the border of Russia and China. This lake is very shallow but has a large area and it is famous for its biodiversity and strongly influenced by flood events. There have been plenty of beach-WoGEs lately, so I decided to take you to another environment. more
Matthew chose to take us to the Baikal Rift with his WoGE #326. The Olkhon island is almost as large as Madeira and has some fascinating tectonic features, thanks again for pointing me to that great spot, Matthew! Now it’s time for a new challenge. Find the following feature on GoogleEarth, post the location and a brief description of the geology in the comments, and all the fame will be yours. more
Matthew’s WoGE #305 showed one of the rare sandstone outcrops in Georgia, the Broxton Rocks. The best hint was in the image source: “USDA Farm Service Agency” led me to search the US, and from the vegetation and the shape of the fields (and the E-W river!) it didn’t take too long to find it. But he was right – finding out about the geology wasn’t that easy.
Felix‘ WoGE #293 led us to a giant dune field in northern Namibia, adding one more location to my where-I-need-to-go-list. The dunes stretch over hundreds of kilometers across southern Africa, which made it not too easy to find the actual spot. Luckily, I came across Heike’s thesis. Felix asked me to show some evidence for tsunamis in the Mediterranean in the next round, so find out whether I did or not. Should be rather easy. more
I found Tannis‘ WoGE #289 more or less by accident, just having a quick look and suddenly realizing that I am in the right area. It was more difficult to find some literature about the Bomapau and Kiriwina Islands. A great area, very high seismicity and a complex tectonic situation. Seems to be a fantastic destination for holidays as well, all those beautiful atolls must be great for divers. more
