The heart of the GSA Cordilleran Section meeting is over; the Wednesday session will be just half a day, giving me time for a side trip or two before the post-meeting field trip. It has been fun hearing from and talking with some of our local West Coast experts and the visiting experts who have ...

I'm spending most of the week in Fresno, California, at the Cordilleran Section meeting of the Geological Society of America. Yesterday, in one of the preliminary field trips for the event, I joined a party of 25 to visit the fossil collection from the Fairmead Landfill project a few miles north ...

If you think you know your way around, think again. A geologic map will transform the way you see your stomping grounds. The familiar features—roads, cities, buildings and all that—are grayed out while the aboriginal land itself shines forth in colors, patterns and lines. Sprinkling ...

On 17 March 2013, NASA cameras captured the brightest impact on the Moon seen in eight years of monitoring. It lasted only a fraction of a second, but at the brightness of a fourth-magnitude star it could have been seen by anyone with binoculars and possibly with the naked eye. Six of the 17 fra ...

When I went to geology school, I was already so advanced that I never used mnemonics—those anagram sentences that help students keep track of the names of the geologic time periods. A reader in the Forum has been using the good old sentence "camels often sit down carefully, perhaps their j ...

In addition to the actual fossils, I do have a decent record of seeing live animals while out in the field, and the DPP and environs of the Tyrrell were no exception. The dinosaurs are of course, awesome, but it’s nice to see some wildlife too. Mark Graham had mentioned in his guest post that I’ ...

Way back in the mists of time, say around 1970-71, an idea was doing the rounds that because the thermal conductivity of continental crust is lower than that of the ocean floor it should allow thermal energy to build up in the mantle beneath. In turn that might somehow encourage the formation of ...

Our high wilderness (Credit: T.A.Rector, I.P.Dell'Antonio/NOAO/AURA/NSF) It’s only 240,000 miles away, yet this high wilderness still surprises and delights with clues about the origins of the solar system, Earth’s own water, and it even  supplies the occasional brilliant ...

This week we opened the first of 17 jackets from the Yorktown whale, which we’ve nicknamed “Cornwallis”. I had not planned to open any of these jackets until the fall, but it turns out we needed a large whale vertebra for a temporary exhibit opening at VMNH this summer, and “Cornwallis” is the l ...

The Moore, Oklahoma tornado of May 20, 2013 is now ranked an EF-5, making it one of only 59 U.S. tornadoes to achieve that distinction since record keeping began in 1950. The National Weather Service in Norman, Oklahoma announced Tuesday that their damage survey teams found an area of EF-5 damag ...
