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. I took this picture yesterday when I was hiking on Table Mountain here in Cape Town with my family.
