Monday Geology Picture: Roots and Rock
It’s been over a month since I posted a “Monday Geology Picture”. Apologies for that — I was traveling (4 weeks in a row!) and was very busy. Anyway, I’ll try to post regularly again now. Today I’m sharing an impressive example of biological weathering, which is when a living organism contributes to the weathering of a rock. In this case, large tree roots are breaking apart a sedimentary rock. …

Monday Geology Picture: Airplane View of Table Mountain
Yesterday morning I flew back to Cape Town after a business trip. I arrived a little after 7 am and was treated to a stunning view of Table Mountain and Lion’s Head as I flew in. I’m sharing a picture I snapped of that view as this week’s geology picture. Here’s a closer look as well: I am lucky to live in such a beautiful city! However, you can see …

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: 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 …

Monday Geology Picture: A Vineyard & the Cape Fold Belt
For this week’s “Monday Geology Picture” here’s a view of the Cape Fold Belt with a vineyard in the foreground. I took this picture yesterday when I took a short walk with some friends through a vineyard located in the Stellenbosch winelands, just outside of my home city of Cape Town. You can see some impressive folding in those distant mountains!

Monday Geology Picture: Intaka Island Salt Pan
For this week’s picture, here’s a view of a salt pan on Intaka Island, a small nature reserve in the Century City area of Cape Town. I often go to Intaka Island to paddle in a kayak on the canals surrounding the island. On Saturday morning I went for one of my usual paddles, and then in the afternoon I joined some friends for a nature walk on the island itself. …

Monday Geology Picture: Old Maps of Africa
Earlier this year I visited a local wine farm here in the Western Cape of South Africa, and there I saw a lovely display of some reproductions of some old maps of Africa. I’m not sure about the background of these maps, but I snapped a few pictures because I thought they were interesting. If you recognize any of the maps, please let me know in the comments. Here are a …

Monday Geology Picture: Granite Boulder in the Forest
For this week’s “Monday Geology Picture” here’s a shot of a pretty granite boulder that I spotted during a forest hike in the Constantia region of the Cape Town, South Africa. No doubt, this boulder consists of ~550 million year old Cape Granite. There’s no scale in this picture, but the boulder is about 2 meters wide.

Monday Geology Picture: Folded Mountains in Hermanus, South Africa
Over the weekend I participated in a kayak race that was held in the lovely little coastal town Hermanus, South Africa. The race was held on a lagoon with a beautiful background of mountains that are part of the Cape Fold Belt. You’ve seen pictures of this fold belt before here on Georneys. For example, here the belt is featured in one of Callan’s “Friday Fold” posts. However, these mountains …
