I confess that I didn’t know the geological conventions for abbreviating time until I started teaching the geology writing class and looked them up. (That’s despite having published a paper on argon-argon geochronology. Sometimes, just doing whatever the co-authors and reviewers say is the right thing to do…) So I don’t have any strong opinions…

The June Accretionary Wedge is up

The June Accretionary Wedge, “Let’s Do a Time Warp,” is up at Outside the Interzone. It’s a crazy time-machine ride from before the Big Bang all the way into the tectonic future. Come along with the geology bloggers to a few of our favorite times. (And, no, the Cretaceous-Tertiary Paleogene boundary didn’t make anyone’s list.…

But when those 2.6 million years include the glacial episode popularly known as the Ice Ages (and the evolution of some weird naked ape), well… scientists can get pretty…

The Accretionary Wedge, the monthly carnival of geology, is still alive! Or, well, it’s still active, at least. Its originator, Brian, got too busy to keep it up, so he handed off responsibilities to Lockwood (of Outside the Interzone), Chris (of goodSchist and the Podclast), and me.

My husband and I both had goals for our visit to the Grand Canyon at the beginning of this week. He wanted to give himself a workout that would leave him feeling sore all week. I wanted to check out the Trail of Time, an exhibit that some of my colleagues from New Mexico and…

I’ve got one wallet-sized version of the 1983 Geological Society of America time scale in my field pouch, and another page-sized version that used to be taped to the wall in front of my desk. I relied on it a lot, especially when starting work in a new field area. In the early 90’s, when…
