Yellowstone National Park last night (View from the Mount Washburn Fire Lookout).

Beautiful colors and panoramic views from the Mount Washburn Fire Lookout camera last night. The foreground shows a section of the trail system used to access the mountain. Lit by the sun, the Grand Canyon of the Yellowstone cuts through the center of the image. In the distance on the right, the Tetons in Grand Teton National Park can just be seen. Blue sky, an arrangement of clouds, green vegetation, sunlit canyon walls, combine to create a wonderful scene from one of the most spectacular sites in Yellowstone National Park.

Having discussed "fjärd", here's another landscape feature that's super common around Stockholm but apparently nowhere in the #English-speaking world: "häll". It's an almost horizontal, smooth, slightly convex expanse of gneiss or granite bedrock. It's what's left of a taller outcrop after the inland ice has ground it down. Maybe there's a #Scots word for it?

#Wavellite crystals #Arkansas#USA

Aluminum basic phosphate mineral with the formula Al₃(PO₄)₂(OH,F)₃·5H₂O, typically appearing in green to yellowish-green hues.
It was named in 1805 by William Babington in honor of Dr. William Wavell, a Devon-based physician and naturalist.
Wavellite commonly forms in fractures of aluminous metamorphic rocks.

"Tsunami warning in effect along parts of Alaska’s southern coast after 7.3 magnitude earthquake" by KOIN News (CBS Portland Oregon) - M7.3 #quake in Alaska's Aleutian Islands led to a local/regional #tsunami warning just for Alaska Peninsula and Aleutians. No tsunami danger for coastal BC WA OR CA. https://www.koin.com/news/national/tsunami-warning-in-effect-along-parts-of-alaskas-southern-coast-after-7-3-magnitude-earthquake/ #earthquake #geology

New models improve predictions of snow, rock and ice avalanches

A new 3D simulation tool developed by ETH and SLF researchers now allows for significantly more accurate predictions of complex alpine mass movements, supporting alpine risk management.

The model produces the most accurate simulation of the disaster in Blatten.

A 3D model of the mountain above Blatten and the simulation of the rock- and glacier slide which hit the village some weeks ago.
