2:16 PM | New List of Awards – Nominate Deserving Scientists!
From Emily Lakdwalla: Before women can be recognized for their contribution to planetary science and astronomy, they have to be nominated. Anecdotal evidence suggests that women may not be getting nominated for prizes very frequently. To encourage people to nominate more women for prizes, I asked Planetary Society web intern and fellow Woman in Planetary Science Tanya Harrison to scrounge […]

1:21 PM | Root wedging: a recent example
What is Kenny pointing at here? Why, it’s a boulder. Where did it come from? Look uphill: This is as perfect an example of root wedging as I’ve seen! Spotted it last Friday along the C&O Canal towpath.

12:16 PM | We need clear policy on tweeting from academic conferences
When Susie Maidment presented her in-progress research at SVP in Berlin last week, someone came in late, missed her “no tweeting, please” request, and posted a screenshot of the new work (since deleted). On the back of that, Susie started an interesting thread in which it became apparent that people have very different assumptions. She, and Marc Jones, and […]

11:30 AM | Imaggeo on Mondays: Painted Hills after the storm.
The geological record preserved at John Day Fossil beds, in Oregon, USA, is very special. Rarely can you study a continuous succession through changing climates quite like you can at this National Park in the USA. It is a treasure trove of some 60,000 plant and animal fossil specimens that were preserved over a period […]

8:00 AM | To Explore a Wild Cave: The Underground Wilderness of the Sierra Nevada
There is a treasure in the Mother Lode of California's Sierra Nevada. It lies hidden beneath the surface, but it's not gold. It is a wilderness, but has no beautiful trees or distant vistas. It is dark and sometimes can be a bit creepy, but it is a place of incredible beauty as well. It is a network of caverns, hundreds of them. A half-dozen are tourist destinations, with lighting, pathways, and guided tours. The rest lie hidden, protected from vandals and abuse only by their secrecy.I had the […]

6:28 AM | We must manage global warming risks by cutting carbon pollution, top scientists conclude
Last week, the Intergovernmental Panel on Climate Change (IPCC) published its latest Synthesis Report, summarizing the scientific research on the causes and impacts of global warming, and how we can mitigate its consequences. The report included various graphs showing how we’re changing the Earth’s climate, and concluded that humans are causing rapid and dangerous global warming. Human influence on the climate system is clear, and recent anthropogenic emissions of greenhouse gases […]

Saturday I led a walk for the members and friends of Wild Oakland to show off one of Oakland’s most striking places to encounter the Hayward fault. There was a nice turnout, about 60 people. I was glad to see so much interest. I hope that this post will enable those people, as well as […]

12:12 AM | Lesser‑Known Yellowstone – Red Mountains
When I was hired as a seasonal interpretive ranger at Yellowstone back in May of 2011, I knew few details about our first national park except that most of it is in northwestern Wyoming, it encompasses a ginormously snoozing yet still active volcano, and its yearly visitation numbers average somewhere in the bazillions. Fortunately, I quickly discovered that there is much more to Yellowstone than simply geysers and tour buses. There are also mountains, and many of them were here long before the […]

10:38 PM | Geo 730: November 9, Day 678: Log, Log, Log!
I'll spare you the bulk of the photos I took of this beautiful petrified log we found at the visitors' center at Cascade Locks. I'm pretty confident this is from The Eagle Creek Formation, which contains a lot of petrified wood and leaf fossils, and has been dated as early Miocene in age. So it's younger than similar-looking plant fossils in the Sweet Home-Quartzville area, which are Oligocene. I haven't found a good on-line reference to The Eagle Creek Formation, but Interzone's wi-fi is […]

5:38 PM | Port Discovery: Woodman Marsh and Old Driftwood
 I have walked this shore reach a number of times in the past on the way to or from other sites on the coast of Port Discovery. Port Discovery is the large bay west of Port Townsend named by Vancouver for his ship. On this particular day the tide was not ideal for a shore walk as it was covering the entire sand and gravel beach and had reached the grass covered shore of this marsh.This particular marsh is slowing shifting from wetland marsh to non wetland marsh as soil accumulates and […]

4:46 PM | Why GMO labeling in the U.S. needs to win only once
There were no doubt celebrations last week in the boardrooms of corporations that own patents to the world's genetically engineered crops. Proposals to label foods containing these crops--commonly called GMOs for genetically modified organisms--were defeated soundly in Colorado and barely in Oregon.That makes for a perfect record in the United States for the GMO purveyors who have beaten back every attempt to mandate labeling of foods containing GMO ingredients. But, I think the celebrations […]

10:29 AM | Subduction is not the end
Subduction is just the beginning. Stuck on the surface of the earth as we are, it’s easy to think that when oceanic lithosphere is destroyed when it vanishes into the mantle. But this is wrong. The more we manage to peer … Continue reading →

7:25 AM | A Different Canada Goose, the Cackling Kind: Evolution on the Continent
Isolation brings about evolutionary change, and the Canada Goose clan has been doing some changing over the last few thousand years, especially in Hawaii, but also here in California. Today's blog is cross-posted from my new birding blog, Geotripper's California Birds. If you've ever been accosted by a Canada Goose at the local park, pictures like these might give you the shivers. If one of them can deliver a nasty bite, just imagine what a few thousand of them can do. But take heart, these […]
