Gasp. Take a look at these cathodoluminescence images of felspars (sanidine and plagioclase) and take that back! These erupted out during a crystal-rich supereruption. Feldspar textures are amazing. And don’t forget the kspar megacrysts in Yosemite!
Multiple black and white images of intergrown sanidine and plagioclase grains that exhibit complex zonation, sieve textures, and bright rims. A black and white image of a sanidine with wild textures. Internal zonation is abruptly truncated by a bright rim. Plagioclase inclusions are present in the bright rim (darker grey minerals)

Karl Poppers paradox of tolerance needs to be spread far and wide. Unfortunately, we may be too late. I really hope we aren’t.
A comic about Karl Poppers paradox of tolerance using nazis as an example. If we extend tolerance to the intolerant, the tolerant will eventually cease to exist.

I couldn’t come in person to present my #IAVCEI2025 poster, so here it is for you all to enjoy!

Nine reduced rhyolites erupted in quick succession in the Mono Basin (Eastern California, just north of the Long Valley Caldera) ~6,000 years ago!

Conference poster titled “Paired zircon and allanite dating of late Pleistocene-Holocene Rhyolites in the Mono Basin, Eastern California, USA”. The poster displays a geologic map, a backscattered electron image of allanite, fayalite, and magnetite grains, a whole-rock geochemical plot, U/Th isochrons, and an age summary plot showing how our method greatly increased precision compared to previous methods.

Here’s a video with a nice hawk gracing me with its presence. If you know what type of hawk this is, please let me know!

The Pacific Ocean with some granite cliffs in Montara, CA. I hope it brings some momentary peace, like it did for me.
Ocean view with some crashing waves and steep cliffs. Another beautiful ocean view with some weathered granite cliffs.
