Riding the line between rock mechanics and geochemistry. Kikuchi patterns, shear zones, deuterium, and cats. Assistant Professor of Rock Breaking. Woohoo.

Turns out wearing bunker gear and level A suits for ten years is useful when the paint in your home office *might* have lead in it.

Several months later, we have bike options again.

Today’s the day to move out of the office and rock storage at CC. Any guesses on how much the pile weighs? (I have a pretty reasonable idea)

Soon, we actually get to experience our new kitchen floor! (Plus cats, because always cats)

Pure shear-dominated shear zones that haven’t been mapped previously? Yes, please!

My 38th birthday present to myself was to make our last rent payment (ever?)! At the end of the month we move to Granville to hang out with these new neighbors.

TWO submissions in one day?! Now we just gotta hope reviewers turn up… (photo 1–Slide Lake Shear Zone with CC students, photo 2–Cordillera Blanca Detachment with Nadine and Micah)

Time to avoid the news cycle for a week.

Pretty solid match for the down-dip projection of the Ama Drime detachment. Very remote, but a few small villages with little infrastructure.

#FoldFriday and #FloatFriday in one swoop with this block of complexly deformed Paleoproterozoic gneiss from near Homestake Peak in central Colorado.
Our paper contrasting regional folding with simultaneous contraction and extension in a pair of shear zones in the area should be submitted soon!

I’m all for bringing #ThinSectionThursday to Bluesky! Hope folks like this XPL image of a brittlely overprinted mylonitic granite from the Cordillera Blanca shear zone in the Peruvian Andes!

On Wednesday, my intro class was supposed to go into the field. Instead, we got a foot of snow and the onset of a depressive episode. Our class became an impromptu study in mass movements (sledding), mixed phase rheology (enchiladas), and astrobiology (Mars Attacks!).

Spent last week working on the Slide Lake shear zone system based out of the 10th Mountain Division Hut with my rheology class. 10/10 would recommend dedicating 5 days of class to working out of cell service with amazing scenery.

When your alma mater dug their structural geology hole, you definitely get to giggle when they can’t find their way out of it, right?
(lines vs planes and what’s required to reconstruct a strain field if you’re wondering, Marrett and Peacock would be SO disappointed)

Climbing up steep and narrow gullies turns out to be a lot more challenging with a block of fresh titanium in your shoulder and your arm in a sling… Regardless, it’s been a blast watching things click into place for this group while co-teaching with (and learning from) @sarahschanz.bsky.social!

Wahoo. Also, apparently I can’t handle my anesthetics.

Happy Halloween from a cold, but wonderful day in the field. Turns out that stormtroopers are also inaccurate with a brunton.

Day one of mapping intrusive relationships and strain fields supported by feeder dikes in an unnamed quartz monzonite in Elevenmile Canyon went well. First overnight of Advanced Field Methods and more mapping today and tomorrow!

Well, I’m exhausted, but thrilled that today was a success. Bittersweet that the first GSA session I chaired was honoring my advisor’s early retirement, but so happy to have brought these wonderful folks together and to have completely filled the room all day long!

Sure, gem quality stibnite is stunning, but let’s be honest, it’s mostly just toxic. Quartz on the other hand, in addition to abundant scientific utility and geologic significance (it defines strength of the upper-middle crust!), is beautiful even at its least prismatic.
