  • BIG crater or caldera in Eastern Russia

    From what I read, not much is known of this landmark, it is not known if it is an impact crater or a caldera (the area has many volcanos). My question is - note what looks like roads into the center through the lowpoint - what are the Russians doing there? Nuclear stuff?

    Lat = 57.59376
    Long = 134.6609
    Alt = 30km

    This thing is so big it only disappears when you are over 1000km up!

    That's pretty cool.

    Url and screenshots for the lazy (aka me).
    worldwind://goto/world=Earth&lat=57.60970&lon=134.65141&a lt=35784

    That looks like a glacier coming out of the middle.

        I have just completed 2 add-ons, Impact Craters and Volcanoes that were active in the last 10,000 years. It is not either of these. I would say it is a volcanoe but old.

          If you look at it, it looks as if it may have had a rupture from that side, and that could be the flow of ancient lava. Maybe it had a side blowout and left it looking like that.

            I just cannot get this stuff to come up clearly at all. I've tried all the USGS.

            It's frustrating.

              The "US" in USGS is "United States". This particular place is in the Russian Federation, in Siberia. The clearest you're going to get is Landsat 7 NLT or Landsat 7 WWC, and that means that around 10,000 meters is your minimum altitude before things start blurring "too much".

              About as clear as you will get (so far) is to use "USGS Urban Area Ortho" and go to someplace like:
              worldwind://goto/world=Earth&lat=38.62754&lon=-90.18756&alt=2283&dir=5.9&tilt=4.6
              ...where you can zoom in to around 500 meters or so before things start to get too blurry.

              If you still get blurriness, you may have a video card issue - you may need to update your video drivers or adjust the card settings.

                It's one of the the largest placer platinum deposits in Russia called "Kondyor". What you can (or cannot) see inside this huge "crown" are mine workings, factory and roads. Unfortunatelly I have no idea how this magnificent Kondyor Massif originated.

                  Unfortunately Worldwind has no tape measure function.
                  Via MS Encarta you can see that this object has a diameter of approx. 10 Km. Very huge!

                  It must be exciting to see this object in natura.

                        you can download a .pdf-file about Russian mining at

                        Russian PGM Mining

                        at the last age (page 6) there's an image of the river outlet from the crater.

                        ... from the images, it's a rather isolated place ...

                          Siberia is full of such isolated places

                            Well its amazing what you can do when you have the right keywords to Google!

                            Here is a sample from a web page I found:

                            "Cosmic photo pictured on the front cover of the book shows the morphological peculiarities of the Kondyor circle mountain ridge and of the Kondyor Massif located in it (geographic position 57o36’N and 134o37’E). Now, morphology of the Kondyor structure is represented by the erosion crater rimmed by the perfectly rounded circle mountain ridge. Hills inside the circle ridge are formed by dunites covering the total area about 20 square km. The river Kondyor, its length beeing 22 km, originated from the confluence of several streams in the central part of the massif, „cuts" the circle ridge in the north, flows into the river Uorgolan which influxes into the river Omnya.

                            Both large and small nuggets of platinum often occur in the upper part of the placer (inside of the circle ridge). The unique nugget of platinum weighing 3521 g is also shown on the front cover of the book. It was found at the confluence of the brook Dvuglavyi and the river Kondyor (nugget location is shown by the arrow).

                            Annual platinum output of the mining enterprize „Amur" from the Kondyor placer deposit of Aldan Province amounts to 3 metric tons. "

                            You can even buy a piece of this landmark, here are some samples of gold-coated platinum you can buy if you're so inclined:

                              ... and who knows what is the origin of this Mordor like circle of mountains ?


                              There is some informations here : http://www.fegi.ru/FEGI/PAPER/zalisch.htm, but it can 't be understood by non-specialists
