For this week’s “Monday Geology Picture” post I thought I’d share a picture from my trip to Dullstroom in Mpumalanga, South Africa, a few weeks ago. I took this picture as we were driving late one evening, just before sunset. I didn’t take a close look at the rounded boulders dotting the field, but they are probably granitoids or possibly dolerites. Although don’t take my word on that– it’s difficult to identify rocks when driving by them rather quickly!
