Here is an image of pyramid-like star dunes in the western part of Mesquite Dunes in Death Valley during a windstorm. These are accessible from the Mesquite Dunes parking area. It is usually pretty crowded.
But we are going to check out the far eastern area of Mesquite Dunes. There is a small parking area over there that is rarely visited. You can wander into the dunes and interdunes and find some especially interesting features....
Earth's distant future is bright. Maybe a little too bright! ☀️ 😎
"Modelling the climate of the new supercontinent [...] found that much of Pangaea Ultima will experience temperatures of higher than 40 °C, making it uninhabitable to most mammalian life."
If you rewind the live feed to 15:20 (edit: the time on the screen from the webcam - not the YouTube video time) you can see when the lava overflow starts. Takes a few minutes. I’m no expert but it looks like increased activity.
Old friends. Many miles and rocky paths we have traveled. We have seen landscapes hundreds of millions of years in the making.
We have traveled through sun scorched rock, icy slopes, and glassy shards. I have doffed you to protect you from stream crossings, and worn you through them when I could not.
Over decades, your utility has barely faded. My capacity to test your limits has been reduced.
Picking back up on the GSA #cave#geology field trip. Day 2, cave 3.
This was after Mammoth cave, we went to nearby by Crystal Onyx cave. Unlike Mammoth this was a wet cave with lots of drippity dissolution and deposition #karst features.
Yes, it seemed to start out touristy-cheesy. But WOW! did it have a lot of neat geology going on!
We were the last tour of the day, just us geological nerds. So we hung out here waiting for our guide and the amazing discoveries below....
Geologist friends, #Perseverance just drove over vein-like crumbly looking rocks. They have a very high albedo when crushed/cleaned from dust.
Could this be something like gypsum or chalk?
The image has been color calibrated and white balanced to the calibration target of the rover. This should be close to what the human eye would see standing on Mars.
My big #cave#geology thread. This was a trip examining a section of Coldwater Cave in Iowa as an Earth analog for #PlanetaryCaves. We were using this as an analog for #karst caves that might exist on Saturn's moon #Titan.
Can I get some follow recommendations? I’m acutely aware that of the people I follow who post about our planet’s systems, most of them are climate people. I’d love to follow more people posting at a #systems level. Y’know, the people who distill down expert knowledge into consumable packets for the rest of us. Think #hydrology/ #freshwater/ #oceans, #biodiversity, #ecology, #biology, #agriculture, #energy, #economics, #geology#planetaryBoundaries … these kind of topics. Boosts appreciated!
Wow. People who were camping waiting for the new volcano to erupt were able to capture one of the fissures opening. Remarkable. I’ve wanted to see how this happens for years. Now we have video 🥰
Thinking about my future... I have skills in IT, art and now possibly in geo/paleo. I would want to mix them together and have a well paying stable job sometime in 1-3 years from now on. Any ideas? Any sphere needs such soup of skills?

A friend who lives not far away from here had visited many times, never having seen any blue rocks. He went with us and we happened to arrive at low tide. And there were the blue rocks at Blue Rocks. :)
The new Reykjanes eruption may not be a tourist friendly one, but it will be a webcam friendly one due to the short days. Lots of darkness to show the orange fire fountains. 🌋
I used to follow a "Microckscopia" accont on the bird site that publish these images of polarized light shone through thin slices of many different kinds of rocks. Any chance you heard of that account, or know anyone doing that?
Somehow, Europe and Spain are not the places where I would like expect something like this. (But then again, I would also not expect volcanoes in Germany and the Eifel is very much here...)
