1:04 PM | The Code of Hammering
As field season returns in my part of the world, I'm gearing up for some nice outings. So it's time again to present my code of hammering. There are guidebooks that touch on matters of professional practice, and every rockhound group teaches its members hammer safety. But as an amateur geologist I practice a game between that of the professional and the rockhound. It incorporates a respect for the rock as something with its own aesthetics and right to exist as nature made it. See if you […]

1:00 PM | Thirsty Thursday: Porter Ahoy!
OK. I actually started this brew more than a week ago. But then suddenly… time passed, and I didn’t blog about it. What’s up with that? So I started a porter two Sundays ago. A honey porter. This weekend, it’s … Continue reading →

12:17 PM | Vitruvian Geology – Leonardo da Vinci and the Realistic Depiction of the Earth’s Surface
In the Renaissance (1450-1600) architecture and pictorial arts, but also scientific disciplines like astronomy, physics and medicine, experienced a rebirth and important improvements – but what about geology? There were some lone geniuses in the earth sciences – Italian artist Leonardo da Vinci (born April 15, 1452-1519) recognized fossils as petrified remains of former living [...]

12:15 PM | Pseudopictographs
I found this interesting looking slab of gray limestone last summer in the Bridger Range of Montana, in one of the talus slopes on the north side of Sacagawea Cirque. The high-contrast pattern reminded me of something, but I couldn’t say quite what. Then I realized: it looks like one of those indigenous pictographs, where the artist puts their hand up to the rock and spits paint all over it, …

7:51 AM | One of the World's Most Precious Places, Under the Volcano
Yosemite Valley, hands down, is one of the most extraordinary places on our amazing planet. I have been going to Yosemite National Park three or four times a year for the last quarter century, and I never get tired of spending time there. The thousand square miles of national park that surround Yosemite Valley are incredible, but the valley itself is hypnotic. I would hope that everyone could visit the park at least once, but it becomes something special when you can see it throughout the […]

7:48 AM | Citibanker: the age of renewables is here
Kathryn Ryan’s interview earlier this week with Michael Eckhart, Managing Director and Global Head of Environmental Finance and Sustainability at the giant investment bank Citigroup was arresting. He was in New Zealand as a keynote speaker at the Wind Energy Conference and Ryan asked him about a recent report from Citi, Energy Darwinism: The Evolution […]

7:02 AM | Meesc
My previous post Policy? trailed off in the comments in a variety of odd directions, as long comment threads are wont to. So I’ll offer you this quote: For there are some people on the left who keep insisting that economic growth is incompatible with reduced emissions, and that therefore we have to turn our…

5:06 AM | A Few Deep-Seated Bedrock Landslides in Whatcom County
Shortly after the Oso/Hazel slide John Stark with the Bellingham Herald contacted me and asked if Whatcom County has any comparable landslide risks. In terms of likely imminent threat, there are no sites in Whatcom County that are directly comparable to the Hazel Slide in terms of size and pending risk. The Clay Banks (nooksack-river-temporarily-blocked-by-landslide, nooksack-river-blocking-landslide-notes, further-update-on-nooksack-river/clay-banks-via-DT, and […]

4:57 AM | Orthospirifer Lophophore Brachiopod Fossil
This fossil is a great example of the brachiopod lophophore feeding tubes preserved in a white quartz form. This brachiopod appears to be some sort of Orthospirifer. It was found in the Sellersburg Limestone that formed in the Middle Devonian Period (Eifelian).Thanks to Mary Ann for letting me take some pictures of it.

2:18 AM | What is that? Wednesday: Realistic Dinosaurs
I’m a paleontologist. I’m a little selective about dinosaur toys… understandably. So when I saw this toy set at the drug store yesterday, I had to buy it – if only to protect unsuspecting children from buying it and thinking … Continue reading →

7:50 PM | The Birth of the Wanderers
How did planets originate? This is a question that has puzzled scientists for centuries, but one which they have been able to tackle directly only in the last few decades, thanks to two major developments: breakthroughs in telescope technology and ever-increasing computing power.

5:57 PM | Geo 730: April 16, Day 472: Depoe Bay, Abridged
Looking south-southwest from fnder the Depoe Bay Bridge, you can see the narrow notch the fleet must navigate to get into and out of the harbor. As hair-raising a prospect as that sounds to me, the lack of major currents- even those of tides, due to the restricted size of the basin- means that it's probably a less complicated and risky proposition than in larger estuaries. I'm pretty much guessing here, but I've heard stories about "crossing the bar" from several other Oregon locations, […]

2:18 PM | Heartland logic: More people have heard of Fidel Castro than Michael Mann, therefore global warming is false.
This is a guest post from Narahani.   Or is happening and is good for you, or has stopped happening, or is caused by CO2 but only a little, or is about to reverse due to lots of yet-to-be-discovered negative feedbacks, and clouds. And anyhow, peas and water lilies love CO2 so ramping it up to 1000 ppm would be fantastic. The logic is dizzying.   And yes, Joe Bast repeated his widely criticized statement equating people who support action to limit climate change with […]

11:17 AM | New agricultural trends to feed the world
The agriculture sector needs to double food production by 2050 to meet growing global populations – a tremendous feat considering the challenges posed by climate change, water shortage and how the increase in farming land is not catching up with demand. That’s why scientists are up to their ears looking for ways to sustainably increase production of crops capable of withstanding different environmental stresses.  Read more

10:17 AM | Lip service: it’s all climate action ever gets from Key & Co
As expected, the New Zealand government’s response to the IPCC’s Working Group 3 report on mitigating climate change pays lip service to the science, while maintaining that NZ is doing all that can be expected. Climate change minister Tim Groser’s press release said that the IPCC report’s call for intentional cooperation meant that NZ is […]

5:07 AM | Can’t Get Enough of Cosmos? Netflix Has 6 Hours of Neil deGrasse Tyson
I have mentioned the lectures you can buy from the Teaching Company before here, and one of those lecture sets is a six lecture series called The Inexplicable Universe, by Neil deGrasse Tyson. It’s worth the money IMHO, but before you buy it, Netflix has made available this entire series for its customers. That’s a pretty good deal. Now, this series does not have all the flash bang the COSMOS …
