I’m Ryan, an earth science educator & curriculum developer at two colleges in Central California. I’ve had a hand in some cool virtual field experience innovations, but lately I’m the “Volcano Tissue Box Guy”. I’m pinning my Etsy store link here for when I release batches.

Me, a white guy standing on Johnston Ridge in front of Mount Saint Helens on a partly cloudy day. The mountain is visible with lots of green growth on the landslide zone in the mid ground. I’m leaning on a stone wall with my butt holding a black tissue box cover holder that also looks like Mount Saint Helens. Screenshot of science Fridays website that hosts my virtual field trip to columns of the Giants and Central California. It says science Friday in the top left-hand corner underneath which is a picture of the tallest pile at the columns of the Giants full of brown and black, the salt boulders with a few pine trees in the distance There is a hexagon with a light bulb as a page brake with a title underneath that says embark on a 360° geologic expedition. https://www.sciencefriday.com/educational-resources/360-degree-expedition/

Following the #HayliGubbi eruption, our paper on the Erta Ale dike of Jun-Jul is finally out. InSAR, optical data and seismicity showed the temporal evolution of the intrusion and the interaction of magmatic sources, including a sill inflation in Hayli Gubbi. @earth-science.bsky.social #geoscience

I need to etch a model of this amoeba onto my Lassen tissue box covers, LOL.

So happy to announce our new preprint, “A geothermal amoeba sets a new upper temperature limit for eukaryotes.” We cultured a novel amoeba from Lassen Volcanic NP (CA, USA) that divides at 63°C (145°F) 🔥 - a new record for euk growth!

This is going to be very popular* at all the parks’ gateway towns that rely almost entirely on tourism.

*popular in the sense that I foresee this being protested out of existence by the gateway communities that in many case are, ironically, MAGA-majority.

Campi Flegrei and Vesuvius in the Bay of Naples area are extremely hazardous. Millions of people live in or near restless volcanoes. Not sure if we're looking at a catastrophic eruption in our lifetime, but a repeat of 1538 Monte Nuovo would still be dramatic.

The #HayliGubbi eruption came after a period of unrest that started in June-July 2025 with a large dike intrusion in the southern sector of the Erta Ale rift. Our InSAR study will be out soon but you can have a summary at the link below. @earth-science.bsky.social #geoscience

Places in red measured their lowest Nov. 24 snow depth on record. Some of the sites are low elevation and have many years of zero snow depth on this date, but there's a number of sites at higher elevation that should be covered in snow at this point.

Whelp… we *were* going to go fishing at Fleming Meadows on Don Pedro but the fog was too ridiculous, so we’re driving up to Moccasin hoping it’s above the inversion. Looking down back towards the Central Valley the fog layer was pretty rad.

Fall colors starting to show along our stretch of the Tuolumne River.
Leaves on 10 year-old fire maple trees are starting to transition to a bright bed on the top and transition down into orange and green on the bottom. They are planted next to TID lateral canal where most of the water is drained but the concrete banks have waterlines on the sides and a little residual several inches of water on the bottom of the canal that is reflecting the red trees in the water

It was a road trippin' week!

Camped at Salton Sea State Recreation Area. I walked out of my tent to the water & saw a raft of ~1k redheads one morning. Cactus wrens were a great alarm clock. The harbor at the visitor center no longer reaches the shoreline. Saw hundreds of blue-winged teals!
Photo looking out across white beach with shrubs, towards the open water of the salton sea and mountains in the background. Blue sky with clouds overhead. The white beach is not sand – – it is bleached barnacles, and bits of fish skeletons. Photo looking out at shoreline of salton sea with mountains in the background. Blue sky overhead. Spotting scope on tripod is in foreground. Photo of small pond (harbor) surrounded by marsh grasses and shrubs. The water has started with white birds, which are bonaparte gulls. Blue-winged and cinnamon teals are mixed in along the edges. Photo of channel from pond toward the open sea. End of channel is completely obstructed and overgrown.

A 17-year-old high school senior from McMinnville, OR was detained by ICE during his lunch break — even after telling officers he was a citizen. An agent shattered his window and said, “I don’t care.”
This should outrage every all of us.
