My friends Betsy and Randy are in a tight spot.
Randy has glioblastoma; Betsy isn't able to work while caregiving.
If you are a person of means, w/ capacity to donate to their cause, it would really help them.

I'm grateful for my mental health.
I encountered someone *melting* down today. I had to step in to get them help. It was scary.
Our sanity is so contingent on the proper functioning of the big wad of wet gray meat in our skulls; doesn't take much for it not to work right.
Treasure your cognition.

More Greenland photos, featuring some geology. Scoresbysund has some fantastic exposures of columnar basalts, which are ~55 million years old (young for Greenland rocks!) related to flood basalts when the Atlantic was opening up. Fantastical shapes and fall tundra colors

For #MountainMonday, I'd like to express my gratitude that I can see both limbs of the Blue Ridge Anticlinorium from my campus. Here you can see PVCC nestled up against Carter's Mountain (eastern Blue Ridge geologic province):

Cool inset map from this "Geologic Map of the San Francisco Bay Region," by Graymer, et al. (2006). ngmdb.usgs.gov/ngm-bin/pdp/...
It shows the blocks of crust sliced & diced by Bay Area faults, and how much & in what direction they have moved in the past 34 million years.
