Ole´s Messum Crater survived nearly a month - maybe's everyone busy like me - but his hint pointed to something easy to find ...

Well, let's see now how this goes ...

As usual, your goal is to find out the exact location and the geology of this place and, if you are the first, you can have the honor of presenting the next WoGE.
Rules, tips and previous WoGEs are collected by Felix on his blog and a KML file is available with all WoGEs.

  1. After over a month I have concluded that this place is not where I thought it must be. Is it time for a hint?

    1. It's more than time!

      I don't know if this helps but here it goes: A dramatic encounter between an Ice Sheet and a volcanic event created this unique landscape.

      If this don't help much ... tell me and I'll publish an area 4x bigger!

      By the way ... Felix, Elisabeth, Andrew and all the others ... are you there?

    1. I'm glad!

      By the way, do you think there's others out there? Or is just us 3?

    2. Luis, I think at the moment we are in some sort of crisis and it looks like we are down to three..

    3. The WOGE Twitter account still has 40 followers..

    4. That means that at least 42 people are still paying attention occasionally. I'm not on twitter. ;)

    5. and looking at your score, you count twice :-D

  3. 47.6544°, -110.4395° "The Shonkin Sag is a prehistoric fluvioglacial landform located along the northern edge of the Highwood Mountains in the state of Montana in the United States. The Sag is a river channel formed by the Missouri River and glacial meltwater pouring from Glacial Lake Great Falls. It is one of the most famous prehistoric meltwater channels in the world. [...] Prior to the Quaternary glaciation, the Missouri River drained to the northeast into a terminal lake or Hudson Bay. During the last glacial period about 17,000 to 13,000 years ago, the Laurentide ice sheet blocked the Missouri River and created Glacial Lake Great Falls.[...] About 15,000 years ago, a glacial lake outburst flood occurred. These waters and their attendant debris then carved the Shonkin Sag at right angles across the existing drainage valleys, with the ice sheet forming the northern edge of the channel. Once the ice sheet retreated, the Shonkin Sag continued to provide a channel for water draining from Glacial Lake Great Falls and the Missouri River, albeit at a much slower rate and at a lower level [https://en.wikipedia.org/wiki/Shonkin_Sag]

  4. I did not find something about a volcanic event. Do you know more about this Luis?
