I visited the New Mexico Bureau of Geology...website. Many states have a geology department where you can find geology roadtrip guides, often for free. I downloaded the "High Plains NE New Mexico Raton..." field guide thinking it might identify additional exposures of the K-Pg boundary, where an iridium rich clay layer marks the fallout of the Chicxulub event that wipeout the dinosaurs. But the field guide is from 1961 & it wasn't until 1980 that the Alvarez hypothesis was purposed. 🫤

We have several good-size bits of petrified wood in our yard in southern Oregon. I did some research, and these specimens are likely between 20 and 35 million years old, dating back to the late Oligocene to the early Miocene period. During that period, volcanic activity literally covered some Oregon forests in ash, and that combined with mudflows and silica rich groundwater slowly replaced the log’s organic structure molecule-by-molecule - which preserved grain, growth rings and bark textures. Pretty 🆒 stuff. A study in ‘deep time’, they are…

Antarctica has a waterfall that bleeds.

Blood Falls pours from the Taylor Glacier — but the red is not blood. It is iron-rich brine, sealed beneath the ice for over a million years, rusting the moment it touches air.

The wildest part? Scientists found microbes living inside that lightless, oxygen-free brine. Life really does find a way.

Not all that glitters is gold: I assume this is Fool's Gold, in Quartz (let me know if I'm wrong 😉).
Small amounts of gold can be found here, I've been told, so you never know...

This is volcanic lightning — a dirty thunderstorm. Ash particles colliding inside an eruption plume build up static charge until the whole cloud starts firing bolts.\n\nThe 2022 Hunga Tonga eruption set the all-time record, unleashing more lightning than any storm ever observed.\n\n#science #nature #geology #volcano


🦐 NEW: Sand hoppers are centimeter-long #crustaceans that live on #California #beaches, eat washed-up #kelp, and dig a fresh burrow each night.

Researchers at #UCSantaBarbara measured the excavated #sand at #IslaVista Beach by framing plots before high tide and weighing the mounds the next morning. They found up to 50 kg moved per meter of shoreline daily.

Ukko-Koli, der höchste Punkt Südfinnlands, ist nicht mal 350 Meter hoch ist. Mein Aufstieg wird mit einem der berühmtesten Panoramablicke Finnlands belohnt.
Der Gipfel und seine Nachbarbergen sind charakteristische Relikte der Eiszeit: Gletscher haben diese Felsen über Jahrtausende geschliffen und abgerundet. Die glatten, wellen- und muldenförmigen Oberflächen der Felskuppen überall im Park sind ein sichtbares ein Fenster in die prähistorische Vergangenheit.

🐘 ICYMI: In the pitch-black chambers of #MountElgon's #Kitum Cave, African #savannah #elephants use their tusks to scrape volcanic rock for #sodium, #calcium, and #magnesium.

Generations of herds have hollowed out these deep mineral chambers, passing down an unusual #mining tradition found nowhere else on #Earth.

Recorded at early light in #Ilulissat, #Greenland, Richard Sidey captured the deep creaks and rumbles of a #calving #glacier adjusting its balance.
