After a slow drive last month through the eastern Klamath Mountains, with many stops to take pictures and examine rocks, I now consider myself well acquainted with peridotite. That can be hard to do, because peridotite is almost all deep in the mantle and lower oceanic crust. And most of the peridot ...

I've cared about geoparks for several years, so I made sure to attend a session on geoparks at the Geological Society of America meeting, on 19 October.
