Gum trees have such interesting #flowers, especially the caps that protect the flowers before they bloom. In this case the caps are remarkably hearty.

Maybe, but the leaves aren’t as green. They are more red/purple, so I don’t know.

A pretty classic structural geology outcrop in Kings Canyon NP. The fold is in formerly marine sediments that was metamorphosed as it was sank deeper into the crust as granitoid plutons of the Sierra Nevada rose towards the surface #California #geology #rocks #nature #faultsfolds #mountains

First snow in the Wasatch Mountains in early October this year. The aspens had yet to lose their leaves.

Making candied orange slices today from my last five blood oranges. They make awesome ice cream or yellow cake topping.

Hey @geologytime.bsky.social here are some boron rich minerals…from Boron, CA, home to the largest open pit mine in California and supplier of approx. 1/3rd of the world’s boron.

The Earth currently has two dominant convergent margins, the Alpine-Himalayan belt and the circum-Pacific subduction. This Cassini projection emphasises the latter, showing how it basically extends around the entire Earth with a few minor breaks.

To everyone in the US, have a happy Thanksgiving from an expat in Oz. I’ll be thankful if you all return to sanity. Remember, we’re all in this life together and should work together, not against each other so solve problems big and small.

This Smilodon skeleton displayed at the Utah Museum of Natural History is from the La Brea Tar Pits in California. You can tell because of the dark color of the bones resulting from all those years buried in tar.
