Cycles of Andean mountain building archived in the Amazon Fan - Nature Communications
South American cordilleran orogenic systems have repeated complex magmatic and deformation histories. Here the authors analyze detrital zircons found in the Amazon deep-sea fan that record mountain-bu...

Any Geo folks have suggestions advice for portable handheld XRFs?
Looking to get into that game.

Here's the GVP page of Hayli Gubbi in Ethiopia: volcano.si.edu/volcano.cfm?.... Plume from the eruption can be seen in this Aqua/MODIS image cross the Red Sea to the Arabian Peninsula. #eruption #volcano

Several falls ago, we field-tripped out to Kentucky with students to see these beautiful outcrops of Carboniferous Fort Payne. Here are two perspectives taken with a drone.
Too bad these are ~ 6 hr drive from campus... ⚒️

Wandering the woods in Manchester VT, and pondering these well-rounded clasts. I’m way above the modern floodplain, and these clasts must be fluvial gravels, not glacial till(?). I wonder how the pre-glacial landscape would have looked? Fun times in fall foliage.

Update on my electrification project:
New heat pump installed! So looking forward to burning less natural gas this winter.

Looking at sands from the subsurface coastal plain, and you just never know what you’ll see.
In related news, I just learned the term “protoconch” or an embryonic snail shell. 🐚

If anyone is interested in going to grad school in paleo, I run a workshop series that will walk you through the process. It’s through the Society of Vertebrate Paleontology and it’s free! DM me if interested.

I’m 45 now and recently rekindled a life-long passion for skateboarding. Most Saturday mornings I meet up with other middle aged skaters, some academics, and have some fun while getting exercise. One thing that constantly surprises me is how much things hurt when you’re old.

So, is there some consensus building that the recent 8.8 earthquake caused the new volcanic activity on the Kamchatka peninsula? ⚒️ 🌋

Russia earthquake has caused a 'parade of volcanic eruptions': Expert
Among the active volcanic eruptions was the Krasheninnikov volcano, a previously at least 400-year-dormant volcano.

NOAA has released their official animation of the propagation of this week's tsunami. It took almost exactly one day to reach Antarctica and was reported at 0.6 feet high.

The absolute last place on earth I wish to frolick naked is probably Talladega Natl Forest, Alabama.
My clothes-on experiences in the region (Cheaha) have all included bugs literally biting me to death.

Check out this beautiful lake-fish 🐠 nest. The fish used its tail to sweep the nest clean, essentially segregating grain sizes; sand piled around the perimeter, gravel in the center, outer margins are fine sands and silty mud. Last night there was a strong wind that modified sands with 🌊 ripples ⚒️
