Monday Geology Picture: Another View of Formica Leo Volcanic Crater
Last week I shared a picture of the beautiful and impressive Formica Leo, a volcanic crater located at the Piton de la Fournaise volcano on Réunion Island in the Indian Ocean. Last week’s picture showed the crater from a distance. You can just barely make out some small people in last week’s picture, to give you some sense of scale. However, I thought I would share a closer view of …

Monday Geology Picture: Formica Leo Volcanic Crater
Today I’m sharing a picture of the stunning Formica Leo (foreground), a volcanic crater located at the Piton de la Fournaise volcano on Réunion Island in the Indian Ocean. My husband and I hiked up this crater when we visited the island for a holiday last year. We also hiked up to the top of the volcanic hill in the distance — crossing over a number of lava flows of …

Monday Geology Picture: Newcastle Coal
During my recent trip to Australia, I was able to pick a piece of coal off of the ground — something that I’ve never done before. I was in Newcastle, a coal mining region, for a conference. One evening I went for a walk along the beach, where coal seams are visible in outcrop. The picture above shows a piece of coal that I picked up off of the beach …

Monday Geology Picture: Weathered Sandstone at Cottage Point, Australia
Here’s another picture from my recent trip to Australia. This picture shows a weathered sandstone outcrop that I saw (by kayak!) at a place called Cottage Point. You can see fresh banded sandstone (light in color) underneath a darker weathering rim. Weathering has created some very interesting shapes in this outcrop! There are quite a few sandstone rocks in the Sydney area. They are frequently used as building stones — …

Monday Geology Picture: A Living Fossil Tree
Today is my last day in Australia. Today, my family, some friends, and I spent a few hours exploring the Royal Botanic Garden in Sydney. There are many beautiful and amazing plants in the garden. However, one plant in particular caught my eye: the Wollemi Pine, which is considered a living fossil because until the tree was discovered in the 1990s it was only known from the fossil record. The …

Monday Geology Picture: Sandstone Building Stone
I’m currently on the east coast of Australia, where local sandstone is commonly used as a building stone. Above is a picture that I took this morning. This picture shows some beautiful building stones on display at the University of Newcastle. The cross-bedding and variable coloration of the sandstone layers is just gorgeous. What a lovely building stone!

Monday Geology Picture: Great Barrier Reef View
My family and I are flying to Australia tomorrow, so for this week’s “Monday Geology Picture” I thought I would share a view of the Great Barrier Reef that we took when we last visited Australia back in 2015 — before the serious coral bleaching events of 2016 and 2017. I’ll be sharing more Australia pictures soon, so stay tuned!

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: West Coast Fossil Park
Today I’m sharing a picture of some Pleistocene age fossils that are on display at the West Coast Fossil Park, which is located about an hour’s drive north of Cape Town, South Africa. If you ever find yourself in the area I highly recommend a visit to the park.

Monday Geology Picture: Nooitgedacht Glacial Pavement
Today I’m continuing with my recent theme of blogging about glacial pavements, and I’m sharing a picture of me sitting on top of a glacial pavement at Nooitgedacht, which is near the town of Kimberley in South Africa. I’ll share more pictures and information about this pavement soon. For now, however, you can read a little about the pavement on Wikipedia here. Although this pavement is located about 700 km …
