Guest bloggers: Zach Downes & Wilson Nelson For me, the trip started in Juneau, Alaska.

With the referendum rejected, we thought our readers would appreciate a review of what this might mean for the oil and gas industry in Alaska. A recent article we published in Alaska Business Monthly discussed in detail the trends and specifics of the production tax credits that [...]

One day last week I found myself feeling kind of punky. I woke up a bit dizzy, and found that my blood pressure was higher than it usually is. For that reason, I decided to take a sick day.

As soon as I walked in the door, another ranger [...]

Ha, I predicted this earthquake for last Christmas, although I thought the earthquakes were marching to the north, and not south. So, not much of a prediction...

Heliolites is an interesting coral that I thought was confined to the Silurian period, So I was surprised when my friend Nils sent me a specimen from the Devonian of Germany in a recent exchange. The specimen below comes from the Junkerberg Formation (Devonian, Eifelian stage) near Rommersheim, Germany.Previously I've blogged about specimens from the Silurian of Gotland, Sweden and Louisville, Kentucky. A search of the Fossilworks site (formerly Paleodb.org) shows that Heliolites is known up [...]

Flying back from Alaska on yet another recent trip, I was able to spot Rose Spit, which featured as a Where in the West challenge back in October of 2010. The shape of the northeastern tip of Graham Island — an island in the Haida Gwaii, or Queen Charlotte Islands, off of the coast of British Columbia up near Prince Rupert — always fascinates me.
