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 northern portion of Graham Island, with

I am always interested in non-traditional data sets that can shed some light on climate changes. Ones that I’ve discussed previously are the frequency of closing of the Thames Barrier and the number of vineyards in England. With the exceptional warmth in Alaska last month (which of course was coupled with colder temperatures elsewhere), I

“You might think it’d be hard not to notice 68 million tons of rock and debris suddenly crashing down a mountainside. But when one of the biggest landslides of the past four years occurred in a remote region of Alaska, researchers knew almost everything about it except its exact location.” Quoted from Adam Mann’s blog

WSDOT released an update on February 7 with some conclusions regarding the blockage that has stopped the Alaska Way Viaduct Tunnel Boring Machine, Bertha's progress since December 6. Now they don't think it was necessarily the well casing after all. They cite two factors that contributed to the blockage. First, the cutterhead was clogged with material. You can see an cool short video of a worker unclogging the cutterhead. Not terribly dramatic, but still cool. The second factor was [...]

2013 was a particularly eventful year for the world's volcanoes. Out of an estimated 1,500 active volcanoes, 50 or so erupt every year, spewing steam, ash, toxic gases, and lava. In 2013, erupting volcanoes included Italy's Mount Etna, Alaska's Mount Pavlof, Indonesia's Mount Sinabung, Argentina's Volcán Copahue, and a new island emerging off the coast of Nishinoshima, Japan. In Hawaii, the famed Kilauea volcano continued to send lava flowing toward the sea.Collected here are scenes from the [...]
