Isostasy Man
Since it was Major Clarence Dutton’s 174th birthday yesterday, I thought I’d give him a nod for creating a simple geological concept that almost every geo-freshman finds impossibly confusing. Isostasy should be as easy to understand as a melting iceberg … Continue reading

Solid to the Core
The Earth is like a chocolate-covered cherry. A bit bigger and harder to eat in one bite, but there are similarities. Like a cherry, the core is solid, but floats in a liquid. Next comes a thick layer of creamy … Continue reading

Curse of the Petrified Tree Trunks
Summer driving season is creeping up on us and the world’s national parks want to again warn visitors that removing protected rocks and artifacts can get you into big trouble. With the government, of course. But even worse, you may … Continue reading
