Running the FRANTZ to magnetically separate the garnet from my sample, all the stuff falling out is the less magnetic amphibole. For anyone curious I’m dating the Syros monolith
Deadvlei, the dead marsh It is amazing the effect water can have in bringing life, and then taking it from an area. Deadvlei is a white clay pan in Namibia near the Tsauchab River. During an especially heavy period of rain, the river flooded leading to a shallow surface layer of water forming over the clay pan. This water allowed Camel Thorn trees to grow and then mature. However, during a drought the water dried up, and sand dunes around the edge of the clay pan blocked the river’s flood path into the area. This drought lead to the trees dying, approximately 700 years ago. Despite the death of the trees, the skeletons remain and despite being blackened by the sun, appear structurally as they would have when they died. This lack of decomposition has occurred, again, due to lack of water as the trees cannot decompose without it. ~SA Image credit: https://commons.wikimedia.org/wiki/File:Deadvlei_trees_dunes.JPG

Love me some rocks
yall we went to the most beautiful lake spring today. LOOK at this water 😭

2020: Sequence of Little Blowhole operating. This blowhole was formed from a column dropping out in the Blow Hole Latite, the basal member of the Gerringong Volcanics (late Permian).

We are prepping some plant fossils so watch this space! 👀
This world isn't ready for geocore. This world can't handle it. It's too powerful. Imagine turning every aspect of geology and geologists into a fun aesthetic... All the nerdy rock puns, sciencey bits, dirt digging, bone and stone hoarding glory of geology turned into a fun little collection of pics and beautiful writing to perfectly capture the feelings of geology.
We can make beautiful poetry about the gorgeous array of colors inside a single stone or silly little ones like "hot hot rock, rock so hot, bake on it potatoe tot". Y'all. Geocore would fucking slap as an aesthetic thing. It'd be like normal geology but with more.

Steamboat Geyser, in Yellowstone National Park’s Norris Geyser Basin, is the world’s tallest currently-active geyser. And here we see it erupting. Impressive!
Steamboat geyser has been erupting pretty often for the last year and a half - not shooting the full football field in height it has before, but erupting every few days to every few weeks. Its behavior is totally unpredictable.

Shocked quartz is not actually rainbow, those images are microscopic views of single shocked quartz particles! On a non-microscopic level, this is what it looks like.
A little bit mundane compared to those funky rainbow microscope shots if you’d ask me.
Penitentes Rows of sparkling snow pinnacles range beside a high Andean pass between Chile and Argentina. Silent and eerie, the Agua Negra Pass high in the remote Andes links La Serena in Chile with San Juan Province in Argentina. At an altitude of 15,633ft (4765m) it is one of the world’s highest motoring passes—a tough 12-hour drive with a high risk of plunging into a ravine or of being swept away by a landslide. The sky is dark in the thin air, and the shadowy ranks of the Penitentes—pinnacles of frozen snow 6-20ft (1.8-6m) tall—lining the steep slopes like white hooded figures, add to the spine-chilling atmosphere. In 1835, the British naturalist Charles Darwin thought that the pinnacles were formed by wind action. More recent studies show that these ice pinnacles form when ice is below the freezing temperature of water, but being bombarded with sunlight and undergoing sublimation. Tiny depressions begin forming as the ice sublimates, and sunlight is focused into these depressions, causing the ice to sublimate more rapidly at those spots. The end result is a field of spiky ice, that this photographer described as “hell to cross”. ~JM Image Credit: https://flic.kr/p/5W1xUZ More Info: Penitentes: http://bit.ly/1LUcEXv Video-Penitentes: http://bit.ly/1Fleb4K Betterton, M.

Imagine your mum being so terrified of you becoming a poet like your dad that you accidentally become the world’s first computer programmer instead
dude seeing these Mega high quality images of the surface of mars that we now have has me fucked up. Like. Mars is a place. mars is a real actual place where one could hypothetically stand. It is a physical place in the universe. ITS JUST OUT THERE LOOKING LIKE UH IDK A REGULAR OLD DESERT WITH LOTS OF ROCKS BUT ITS A WHOLE OTHER PLANET?

Imagine being on a caving trip, looking up at the ceiling, and seeing something fascinating on the roof of the cave you’re in. Apparently that happened to one of the geoscientists who authored a paper on this set of enormous dinosaur tracks found in a cave in southern France.

Me, just an unstoppable juggernaut of geology fun facts once I get started: And did you know that Frankenstein and Dracula were written during the year without a summer? A time when Ash from a big volcanic eruption covered much of Europe for the whole summer forcing it into a dark volcanic winter and so the Gothic Mood was influenced by a geological catastrophe at the time. Our art and culture are and have always been heavily influenced by the changes of the shifting rocks beneath our feet and the interplay of how we interact with and react to the world around us is fascinating.
Bryce Canyon was just a little chilly. Mossy Cave had truly blue icicles. And I loved these snow curls. I watched the far left one form.
