Monday Geology Picture: U-Shaped Glacial Valley, Seward Peninsula, Alaska

Monday Geology Picture: U-Shaped Glacial Valley, Seward Peninsula, Alaska

When glaciers erode landscapes, they often leave behind characteristic U-shaped valleys. This week’s Monday Geology Picture shows a U-shaped glacial valley on the Seward Peninsula in Alaska. This valley is located just outside of the gold mining town of Nome. Does anyone else have good pictures of U-shaped valleys?

Monday Geology Picture(s): Two Views from the Top of Table Mountain

Monday Geology Picture(s): Two Views from the Top of Table Mountain

My two American geologist friends, with whom I went ziplining amidst some sedimentary rocks a little over a week ago, left on Saturday. Before they left on their evening flight, we decided to go up Cape Town’s beautiful Table Mountain. We took the cable car up the mountain, hiked around on the top for a couple of hours, and then took the cable car back down. Saturday was a beautiful …

Chamarel Waterfall, Mauritius

Chamarel Waterfall, Mauritius

Today I’m continuing with sharing some pictures from my March 2014 trip to the volcanic island of Mauritius. You can see some of my previous posts on Mauritius here, here, and here. Mauritius is a tropical island, so in many places the lava rocks, particularly the older ones, are covered by thick green vegetation. However, there are some places where you can see the lavas well. One of those places is …

The Young Volcanic Landscape of Mauritius

The Young Volcanic Landscape of Mauritius

For the next little while, I will be blogging about my recent (March 2014) vacation to Mauritius, a young volcanic island in the Indian Ocean. I recently shared a couple of pictures of volcanic basalt in Mauritius for my “Monday Geology Picture” posts here and here. In future posts, I’ll write a little more about the volcanic history of Mauritius. In brief, Mauritius is believed to have been formed by a …

Monday Geology Picture: Black Basalt on the Beach, Mauritius

Monday Geology Picture: Black Basalt on the Beach, Mauritius

First of all, my apologies for the long absence from blogging. Work has been extremely busy this year, and for the last 6 weeks I was in the field with very spotty satellite internet connection. However, I’m back in Cape Town now, and September should be a quieter month for me, workwise. So, I’m hopeful that I will have time to catch up on some blogging. One of the things …

Monday Geology Picture(s): Rocks Flanking the Entrance to the Smithsonian Natural History Museum

Monday Geology Picture(s): Rocks Flanking the Entrance to the Smithsonian Natural History Museum

My apologies for the light blogging recently. I was traveling in the US for three weeks, and now I am traveling for work for 6 weeks. I will do my best to blog when I can, but blogging may continue to be light for a little while longer since I’m currently working 12 hour shifts in the field. However, when I return in September I will be taking some time …

Monday Geology Picture(s): Fossils in the Floor

Monday Geology Picture(s): Fossils in the Floor

My husband and I are travelling in the US at the moment. A little over a week ago we attended an event at the Hynes Convention Center in Boston, and I noticed some interesting fossils in some beautiful building stones on the floor of a hallway connecting the center with an adjacent hotel. I snapped a few pictures of the fossils. Can anyone identify them? Does anyone know where the …
