WOGE #548

After a long hunt for black lava and cinder cones that took much of the Easter weekend, 547 from Paul (http://wogepaulvoestermans.blogspot.ca/2016/03/where-on-google-earth-547-in-woge-546.html) was an easier one for me. The red colour was easier to see on Google Earth, and after search Utah and Arches National Park, I moved south to Australia. There I found Kata Tjuta or The Olgas, located just to the west of Uluru.

From Wikipedia (https://en.wikipedia.org/wiki/Kata_Tjuta): Kata Tjuta, sometimes written Tjuṯa (Kata Joota), and also known as Mount Olga (or colloquially as The Olgas), are a group of large domed rock formations or bornhardts located about 365 km (227 mi) southwest of Alice Springs, in the southern part of the Northern Territory, central Australia. Uluru, 25 km (16 mi) to the east, and Kata Tjuta / Mount Olga form the two major landmarks within the Uluru-Kata Tjuta National Park.

The 36 domes that make up Kata Tjuta / Mount Olga cover an area of 21.68 km2 (8.37 sq mi), are composed of conglomerate, a sedimentary rock consisting of cobbles and boulders of varying rock types including granite and basalt, cemented by a matrix of sandstone.

The highest point, Mount Olga, is 1,066 m (3,497 ft) above sea level, or approximately 546 m (1,791 ft) above the surrounding plain (198 m (650 ft) higher than Uluru).[1] Kata Tjuta is located at the eastern end of the Docker River Road.

Contest #548 is not red, but shades of blue, green and beige.

No Schott rule this time - to give the geologists a chance to wrest the game away from the non-geologists!

Where on Google Earth #544

Felix provided us with an interesting location that initially had me hunting in the Northern Hemisphere for many days before reassessing the shadow pattern and moving south. It was luck that ended up with me scanning South Africa for a circular pattern with small towns along the northern edge.

I hope that 544 provides an interesting search.

Where on Google Earth #536

Paul posted a picture of Sedona, Arizona in the USA for us in contest 535.

The red colours in the picture led me to the southwest US, and quickly I was able to identify the location of the image as the town and surrounding of the picturesque town of Sedona.

http://www.arizonaruins.com/sedona/sedona_geology.html has lots of information about the geology of this part of the world.

This contest has a interesting feature to help the searchers narrow down the location.

Where on Google Earth #534

Paul took us to Iceland and the mid-Atlantic Ridge in Þingvellir National Park for contest 533.

Þingvellir is notable for its unusual tectonic and volcanic environment in a rift valley.

The continental drift between the North American and Eurasian Plates can be clearly seen in the cracks or faults which traverse the region, the largest one, Almannagjá, being a veritable canyon. This also causes the often measurable earthquakes in the area.

Some of the rifts are full of clear water. One, Nikulásargjá, is better known as Peningagjá (lit. "coin fissure"), as its bottom is littered with coins. After being bridged in 1907 for the occasion of the visit of King Frederick VIII of Denmark, visitors began to throw coins in the fissure, a tradition based on European legends.

For contest 534, we stay in a green part of the world.

Where on Google Earth #532

Paul Voestermans, a first time winner in WOGE, gave us an image showing Mount Eiger in Switzerland.  I was lucky to recognize the terrain as on the northern edge of the Alps and then it was a matter of hunting down the exact location.

Mount Eiger has been the site of many deaths of climbers trying to ascend the steep north face, and also the location of many rockfalls over the years.  The last major one was in July 2006, when a chunk of rock as big as a skyscraper fell.  (http://www.nature.com/news/2006/060717/full/news060717-3.html)

For the next contest, we go somewhere a bit drier.

Where On Google Earth #529

WOGE 528 was quite easy to solve - the problem for me as a non-geologist was to identify the geological feature at this location. 

Luckily Google was able to help me out with a link to a Scientific American blog (http://blogs.scientificamerican.com/history-of-geology/january-11-1771-the-birthday-of-lake-alleghe/) with details on the catastrophic landslide event that occurred in January 1771, and resulted in Lake Alleghe forming in this location.

Where On Google Earth #522

It's hard squeezing in between Ole and Felix, but I was lucky this time - and managed to find Ole's #521 after a bit of searching to find the right shade of colour seen for the water and the barren terrain.  

The main item of geologic interest is the circular hole - the cryolite mine at Iviqtut. Cryolite is used in the process of modern aluminum extraction. This location is one of the only naturally occurring locations of this very important compound.

For this contest, let's go somewhere warmer!

The Schott Rule is invoked to give others a chance to solve the puzzle!  This means previous winners have to wait one hour for each win they previously had, before they are allowed to solve. 

As always, the first person to post the position and whatever is interesting about the geology/hydrology/geowhatever in this location, wins the privilege of hosting the next WoGE.

Previous WoGEs are collected by Felix on his blog and a KML file.
