WEGA's NW USA Excursion

At Long Last - WEGA's NW USA Excursion Blog.


At last, 9 months in the making, the record of WEGA's excursion to the North West USA is published. Lots of geology, lots of maps, lots of photos find it HERE.




Gypsum sand dunes

Gypsum Sand Dunes - but the Grains are Too Big!

The Salar de Gorbea in the Atacama in Chile has gypsum sand dunes, like White Sands National Monument in New Mexico, USA. But, at White Sands the grains are small and wind blown, at the Salar they are up to 20cm! But they look wind blown! 

THIS ARTICLE in the Economist discusses how such huge crystals get to the dunes from gypsum producing ponds 5km away. Dust Devils? - perhaps.

Spherical world - flat maps

Map projections

This has little to do with geology but as we are always dealing with maps it is not without interest. read all about it HERE




Dinosaurs revisited - again

Will the Dinosaur Family Tree be Rewritten?

Mike Benton writes HERE that recent research in cladistics might necessitate a reappraisal of dinosaur evolution. I don't pretend to understand it but it is probably important!

Jokes

Geological Jokes

While procrastinating in front of my computer I came across THIS PAGE. I expect that the jokes may elicit a few groans - Some were old when I was a boy in the Holocene.


Geological Photos

Rather Nice Geological Photos - Mostly


I found these photos online and thought some of them were rather good. Hope you like them.
