Triple Divide Peak was Andrew´s challenge - a place I have "visited" and very close to one of my WoGE candidates (one that I think I have to drop...).

Now let´s go to 502: it has the advantage of joining two of my interests, one in geology and another in ... hmmm ... other earth science!

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.
No Schott's Rule!
Rules, tips and previous WoGEs are collected by Felix on his blog and a KML file is available with all WoGEs.

Ale jacta est! ;)

    Mount Stromlo, Australian Capital Territory: 35°19′S 149°01′E

    Geology: "The rock on Mount Stromlo consists of ignimbrite from the Laidlaw Volcanics. This erupted in the upper Silurian period over the top of the Deakin Volcanics rhyodacite which is visible on the surface on the lower slopes in the east and southeast sides. The northern lower slopes are covered with a calcareous shale which is included in the Laidlaw Volcanics as it was deposited at the same time. This is cut off on the northwest side by the Winslade Fault, which heads north east to Cook and Kaleen. A spur fault heads off east from the Winslade Fault to under the Scrivener Dam. On the northwest and north side of these faults are middle Silurian period rhyodacite volcanic deposits from the Walker Volcanics. The northern side was uplifted compared with the southern side." (wikipedia)

    Astronomy: "The observatory was established in 1924 as The Commonwealth Solar Observatory. The Mount Stromlo site had already been used for observations in the previous decade, a small observatory being established there by Pietro Baracchi using the Oddie telescope being located there in 1911. The dome built to house the Oddie telescope was the first Commonwealth building constructed in the newly established Australian Capital Territory. In 1911 a delegation for an Australian Solar Observatory went to London seeking Commonwealth assistance. The League of the Empire sought subscriptions to assist raising funds. Survey work to determine the site's suitability had begun as soon as the idea of a new Capital was established. By 1909 the Australian Association for the Advancement of Science was assisted in this effort by Hugh Mahon (Minister for Home Affairs). Until World War II, the observatory specialised in solar and atmospheric observations. During the war the workshops contributed to the war effort by producing gun sights, and other optical equipment. After the war, the observatory shifted direction to stellar and galactic astronomy and was renamed The Commonwealth Observatory. Dr R. Wooley Director of the Observatory, worked to gain support for a larger reflector, arguing that the southern hemisphere should attempt to compete with the effectiveness of American telescopes. The ANU was established in 1946 in nearby Canberra and joint staff appointments and graduate studies were almost immediately undertaken. A formal amalgamation took place in 1957, with Mount Stromlo Observatory becoming part of the ANU.

    On 18 January 2003, the devastating Canberra firestorm hit Mount Stromlo (which was surrounded by a plantation pine forest), destroying five telescopes, workshops, seven homes, and the heritage-listed administration building. The only telescope to escape the fires was the 1886 15-centimetre Farnham telescope. Relics from the fire are preserved in the collection of the National Museum of Australia. They include a melted telescope mirror and a piece of melted optical glass (flint). The latter has pieces of charcoal and wire fused into it from the fierce heat of the fire.

    Redevelopment is completed and the Observatory is now a major partner in the construction of the Giant Magellan Telescope. The current observatory director is Matthew Colless."

    My search criteria: It looked a lot like Australia. And it looked a lot like an astronomical observatory. So I looked around the sites of Australian observatories...

  2. Once again ... Ole wins!
    I'm thinking in a Ole's Rule: Ole must wait 10H for each victory! Kidding .... just kidding! Keep going, Ole, on with the next one! :)

  3. I will try to get one up before the weekend, life is a bit hectic right now so I can't really promise a quick post...

  4. Woge #503 is up at http://overburdenblog.blogspot.no/2015/08/where-on-google-earth-503.html
