I’m a sedimentary geologist interested in sediment routing systems and their response to changes in climate/tectonics.

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... ⚒️
A view of a roadside outcrop displaying interbedded greenish mudstones and fossiliferous grainstones, packstones, and wackestones. roadside outcrops of carboniferous limestone and greenish mudstone, laid back in three benches. Some faulting present, also present, some interesting depositional geometries.

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.
A Bosch heat pump outdoor unit.

Came across another picture of my slightly younger self doing fieldwork, somewhere Wild and Scenic, New Mexico. Ca. 2012

A favorite picture of mine, taken by none other than @clasticdetritus.bsky.social
in Panamint Valley, CA, ca. 2014ish ⚒️
Me standing in the foreground of a cliff exposing Plio-Pleistocene-aged alluvium displaying large-scale (approx. 10-12 meter) cross-bed sets.

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. 🐚

Spiral shaped fossil, potentially an infilling of a small gastropod mollusk 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? ⚒️ 🌋

Among the active volcanic eruptions was the Krasheninnikov volcano, a previously at least 400-year-dormant volcano.

DOE climate report response form
We are collecting names to assemble a writing team to respond to the DOE climate working group report. If you'd like to contribute, enter your info below. At this point, there is no guarantee what we'll do (if anything), but we want to keep our options open by collecting names. If you have any further questions, feel free to email me. We are primarily looking for Ph.D. scientists at universities or government labs in appropriate fields. I realize that this will exclude some qualified people and I apologize, but we felt this was necessary for a variety of reasons.

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 ⚒️

A look at the sedimentary rocks on Mars that require flowing fluids. Focuses on bedload transport (of loose sediment) to form crossbeds - recognition of these structures provides clues to the former presence of fluids, particularly water.

Evidence for bedload deposition on Mars
Why focus on bedload deposition? Because it provides evidence for fluids (air-water) on the ancient Martian surface

Lots in the news today about the terrible tragedy in Texas. If you want to start somewhere, start with @mattlanza.bsky.social. He knows Texas weather (and tropics) better than anyone, and he's always considerate first to the lives impacted. Also, no this wasn't because of NOAA budget cuts.
From Matt Lanza's July 5, 2025, post on the eyewall about the deadly Texas flooding early Friday: "Did budget cuts play a role? No. In this particular case, we have seen absolutely nothing to suggest that current staffing or budget issues within NOAA and the NWS played any role at all in this event. Anyone using this event to claim that is being dishonest. There are many places you can go with expressing thoughts on the current and proposed cuts. We’ve been very vocal about them here. But this is not the right event for those takes. In fact, weather balloon launches played a vital role in forecast messaging on Thursday night as the event was beginning to unfold. If you want to go that route, use this event as a symbol of the value NOAA and NWS bring to society, understanding that as horrific as this is, yes, it could always have been even worse."

Made a quick 3D model of outcrops of early Paleozoic dolostone (Clarendon Springs, according to Rock’d). Hildeen farm, sandwiched between the Taconic and Green Mountains, is a beautiful property once owned by Abraham Lincoln’s son. 🇺🇸 ⚒️
