Last week Diana Barnes did a slam dunk and scored all 3 points in that competition, it took the whopping time of 39 minutes for her to identify the volcano, the vent and the lavas. An astounding thing since it was a private image given by “Ursula” to me.
She was of course correct with it being in her own words; “Mt. Gambier, South Australia. A Maar Complex rather than a single volcano. Last erupted 4300 years ago. This crater is called The Blue Lake.
The surface rock before the eruption was limestone, a band of which can be seen around the lakeside. Above is Tuff and Ash. The limestones in places has been changed to Dolerite by the volcanic activity.” And that puts Diana at the helm of the competition.
The Score is:
3 Diana Barnes
1 Heather B
This week’s competition
I will award one point for the correct name of the volcanic system. I also want the volcanic event that gave the name, and of course the name of the 2 lavas visible on the image. A friendly hint, just saying basalt won’t cut it. Thanks to Ukviggen for the picture.
Icelandic Volcano BBQ
Also, for those who are going to attend the 14th of July Icelandic Volcano BBQ, it is soon time to book tickets and so on. Also, it would be nice if people gave a heads up on if they are coming when they have decided/booked. I will most definitely be there!
