Oorlogskloof Glacial Pavement

Last week I shared the above picture of the Oorlogskloof Glacial Pavement for my “Monday Geology Picture” series. Today I’d like to share some more pictures and also a little more information about this incredible geologic site. Oorlogskloof is the name of the farm where the glacial pavement is located. The name is Afrikaans and translates as “War Valley”. Oorlogskloof is located about 4 hours drive north of Cape Town, …

Monday Geology Picture: Gold Train

This week I’m sharing a picture of a bullion coach, or a special train that was used to transport gold from the mines in the Johannesburg area to the seaside towns of Durban and Cape Town in South Africa. This particular train is on display at Gold Reef City, a gold mining themed amusement park. You can go and see the train yourself if you visit the park. Gold theft …

Monday Geology Picture: Pele’s Hair

For this week’s post, here’s a picture showing a lovely example of Pele’s Hair, which is a type of volcanic glass that consists of fibers or thin strands. Although I’ve visited many volcanoes (including a few active ones) over the years, I’ve never seen Pele’s Hair in the field. So, I was quite happy to see this excellent example in the volcano museum on Réunion Island. I visited the museum during …

Monday Geology Picture: Constantia Granite

For this week’s post, here’s a picture that I took yesterday during a Sunday afternoon hike with my family. We went for an easy stroll, baby and all, along the Alphen Trail in the Constantia region of Cape Town here in South Africa. My son is 3 months old now, and we’re just starting to go on some easy hikes as a family. The Alphen Trail is more of a …

Monday Geology Picture: Vintage Field Vehicle

I really enjoy looking at old geology textbooks, which often have incredible photos and drawings in them. For example, check out the above photo from an old geology textbook that I picked up at a secondhand bookshop. Look at that vintage field vehicle! Does anyone know what kind of car that is? The information in old geology textbooks (especially ones published before plate tectonics was understood) is often incorrect, but …

Monday Geology Picture: Lion’s Head Inselberg

Happy New Year! I’m going to do my best to blog more regularly in 2018, starting with this first “Monday Geology Picture” post. This week I’m sharing a view of Lion’s Head (the distinctive mountain in the background of the picture), an inselberg here in Cape Town, South Africa, the city where I live. I took this picture a few weeks ago during a walk with my family along Sea Point …

What to Buy a Geologist for Christmas: 2017 Edition

My annual What to Buy a Geologist for Christmas list is very late this year… along with some of my other holiday traditions. For example, I’m generally quite diligent about sending cards, but I have not yet mailed a single Christmas card! I think that my cards will only go out in January or maybe even February. At least I have a good excuse: my son is 10 weeks old …

Monday Geology Picture: Garnet Biotite Tabletop

Since re-starting my blogging, I missed a few weeks of weekly pictures. My apologies! Life with a newborn does not leave much extra time, I’m afraid! I’ll try to be more consistent with my blogging in December and going into the new year. However, I have a great picture for today: a close-up snap of a lovely stone tabletop that I recently saw, believe it or not, at a McDonald’s …

Monday Geology Picture: Inselberg View

For this week’s picture, here’s a lovely view of an inselberg and the Twelve Apostles section of Table Mountain here in Cape Town, South Africa. Note the layers of sedimentary rocks of which the mountain is made. In the foreground, you can see some rocks of the Cape Granite Suite, which is about 550 million years old.
