I'll be spending a week in Mexico City in November. Anyone have local reccs? museums? Pyramids to see? Beautiful parks? Anything else to know or be aware of? (public transit is good? safe? pickpocket prone areas?)

Want the most AREA to map here's your top 12, the smart mapper may pick the lowest surface area ones which are located in the middle of Great Salt Lake 🤣🤣🤣

At the Utah Geo Survey, we've been debating which 7.5' quadrangles have the most surface area. We have our answer and it was surprising! This proxy for normalized relief put the western Tavaputz Plateau as the highest compared with other regions #madewithClaudeCode

Some acquaintances published a very prescient Op-Ed in the Salt Lake Tribune regarding Utah poor preparation for an upcoming earthquake, drawing strong comparisons to Venezuela - take a look! www.sltrib.com/opinion/comm...
sltrib.com
Voices: Venezuela’s earthquake tragedy is a warning for Utah
In an op-ed, four Utahns write that the state “does not lack knowledge or expertise” in earthquakes. “What it lacks is urgency.”

Getting ready for a field trip to the PNW next week, co-leading a Friends of the Pleistocene trip to the Hells Canyon area. We needed an updated reference for the Columbia River Basalt stratigraphy with the latest geochron. Here yah go!

I am not a colorado plateau volcanics expert by any means but it was a fun process and way to evaluate the capabilities of this model, which I was thoroughly impressed by. However, given its cost, I will not be using it again. Although, it seems there's great promise for big data compilation tasks!

Matthew Morriss @rockiceandsnow.bsky.social · 25/07/2026
I had also asked it to look at the geochemistry of the volcanics through time and you'll see below the webapp that it built to visualize the silica content of different volcanic and intrusives.

Matthew Morriss @rockiceandsnow.bsky.social · 25/07/2026
With two prompts and 15-20 minutes it pulled 1700 geochron sample ages as well as volcanic geochemistry and put together the following video of volcanics in the region going back to 45 Ma (per my request).

I was curious to try @anthropic.com's latest model Fable on data retrieval, analysis and visualization. I tasked it with with pulling data on volcanics and intrusives across the colorado plateau, testing the hypothesis put forward by Best & Brimhall 1974; Tanaka et al. 1986; etc.

Funders must take action before an increase in submission of high-quality proposals written using AI models makes it impossible to sort the wheat from the chaff.

What is your own use of LLMs in research and publishing? I've also found it a helpful reviewer of manuscripts and reports I'm writing, giving me feedback.

Question for scientists: I am making extensive use of Claude to help me with coding and also help me make figures. This is a very helpful given the fact that I never got into Earth Science to become a coder. If I'm open about my use of an LLM in the publishing process, is this a problem?

Why map in Utah? The entire state is a geology textbook. From the Basin and Range to the High Plateaus and the iconic red rock canyons of the Colorado Plateau, the stratigraphy and structure here are unparalleled. It’s a dream destination for any earth scientist. 🏜️ 2/6
