Professional societies, I beg you, please shorten the name of the Super-Long-Dude's-Name Memorial Prize in Whatever Studies. It's torture trying to include it in my tightly limited cover letter nominating a colleague for another prize with a name that's way too long. Like, if you just called it the Best Prize or something, I'd save two full lines.

A reminder of how mining typically ignores the safety and well-being of local people.

I see where we are starting to pay some attention to our neigbors to
the south. We could never understand why Mexico wasn't just crazy about
us; for we have always had their good will, and oil and minerals, at heart.

Low Tide At Meyers Creek Beach (2019)
(Near Brookings, Southern Oregon)
Ps. I'd love to know what kind of mineral those red parts might be! 🙏
#TextureTuesday #NaturePhotography #Rocks

An exposed rock at the beach during low tide. Some parts of the rock are dark gray, others consisting of intensely red mineral with some white-greenish dotty overgrowth. Dark gray sands.
