Not to be crassly opportunistic, but if you’re genuinely curious about how there came to be an ocean of fossil fuels in the crust, why humans now emit 100x more CO2 than all volcanoes on earth, and want to begin that story 4 billion years ago, might I recommend www.harpercollins.com/products/the...

Columnar basalts deserve their own footnote in art history… they crop out often (or maybe I am just attuned to them). Eg 1) Isamu Noguchi’s Unidentified Object @metmuseum.org 2) part of Joseph Beuys’ 7000 Oaks on 22nd street, with some recent snow

The world has so much to learn from Norwegians about the critical importance of saunas. (did you guess that I would end the sentence with that word?) Here is a nice sauna overlooking the harbor in Storekorsnes. Spotted while waiting for a ferry transfer back to Alta.

These are cloudberries (with a gabbro intrusion cutting metasedimentary rocks in the background). Cloudberries have a short Arctic growing season and have twice as much vitamin C as an orange by weight.

There were a lot of mosquitoes and biting flies in Siberia. But Norway may have Siberia beat for the sheer diversity of biters… a very heterogeneous mix of small biting flies, giant biting flies, and mosquitoes. All living their best lives

Yesterday we were working near a mine. We thought maybe mining the carbonatites because they are one of the major sources of rare earth elements. But actually they were mining the nephrite syenite to make porcelain! Just a reminder that we use rocks for all kinds of things. Rocks->teacups

First cell reception after two great field days! We are looking at an enormous magmatic system at 5-10 kbar pressure (mid to lower crust). Very volatile rich, including carbonatites (inaccesible today due to snow). Big thank you to @fredrhog.bsky.social for sharing some nice NGU maps of the area.

Quick run around Alta in the morning. Tons of wildflowers on the streets. Some old classic wooden houses…. Plus lots of buildings that feel like bunkers against the winter months

Made it to Alta! Some photos from the flight in. It is 11 PM and the sunlight is golden. Tomorrow we meet up with colleagues from Uni of Lausanne to take a boat out to the rocks

The compare/contrast between Denmark and Norway—photos taken just a few minutes apart across the Skagerrak strait—is stark. Sand vs rock. Next: the journey 1500 km north, to the Arctic

How do others feel about packing for field work? I don’t especially enjoy normal packing, but there is a pleasure in trying to imagine a future moment on an unknown mountain, and what you might wish for in that moment—and then later, with luck, being on the mountain and having just what you need

Leaving for field work tomorrow with a team heading to northern Norway to explore the exhumed remnants of a very large mafic magmatic system—possibly the lower crustal roots of an Ediacaran large igneous province! I don’t know if I will have any internet, but if so I will try to tweet along the way…
