I won the Where on (Google) Earth contest #182, hosted by Dr. Jerque at Geologic Frothings, by correctly identifying the location near Aktash, Altai Republic, Russian Federation. At that spot, some intriguing geomorphic stuff happened once upon time. More specifically, starting in these mountains, spectacular Pleistocene ice-dam failure megafloods raced across the Asian continent eventually reaching the Caspian, Black, and Mediterranean seas. Discharge from these floods is estimated to rival, or even exceed, the Missoula Floods. The location Dr. Jerque put in the spotlight is close to one of the ice dams, has some absolutely spectacular ripple fields, and is just upstream of an amazing gorge created by water rushing up to 45 m/s (162 km/hr, 100 mi/hr). There’s a really nice write-up of the floods, with on-the-ground photos, that can be found here.
Having just searched out one of the most jaw-droppingly powerful geomorphic spots on Earth, I’ve opted to go for something a bit more subtle for Where on (Google) Earth #183. Nonetheless, I think there’s something geo-interesting going on in this image. The eye altitude here is ~15 km and the vertical exaggeration on my browser was set to 2.

First person to identify the latitude and longitude of the image, give a place name, and take a decent stab at why it might be interesting gets the honor of hosting the next round of the game. If you are not a blogger, you can still play, win, and then designate the blogger of your choice to host your image and the next round. I’m invoking the Schott Rule (sorry, Ron), which means that you need to wait one hour after the post time to answer for each Wo(G)E round you’ve won in the past.
