A massive secondary landslide in Devdoraki Gorge, Georgia

The Landslide Blog | 29 June, 2016
In 2014 I posted about a very large landslide that caused extensive damage in the Devdoraki Gorge (which is often described as the Dariali Gorge) in Georgia.  That landslide left a very large volume of debris in the river bed. On 23rd June this debris mobilised into a new, secondary, landslide that caused extensive damage along the key highway that links with Georgia and Russia via the Kazbegi Customs checkpoint.  Thanks to a warning system installed after the 2014 events, no-one was injured, but the damage appears to be significant.  The road remains closed.

(Repost) Adventures in Christianist Earth Science Education IIa: In Which We Are Told About Science!

En Tequila Es Verdad | 29 June, 2016
The best thing about being an adult is that I get to read textbooks by choice*, something my younger self would find fairly horrifying. The other best thing is that I don't have to read them sober.

Considering the Wild Diversity of Frills Among Horned Dinosaurs

The frills sported by horned dinosaurs are fascinating, as are the creative and wide ranging hypotheses proffered to explain this "exaggerated" feature.  Two of the most difficult aspects of drafting this post may have been (1) keeping from getting mired in the vigorous debate over explanations for those frills (I am deliberately cursory in my treatment below), and (2) refraining from a title that grossly punned on the word "frill" (e.g., A Frilling Debate).

Asteroid (441987) 2010 NY65 passes the Earth.

Sciency Thoughts | 28 June, 2016
Asteroid (441987) 2010 NY65 passed by the Earth at a distance of 4 118 000 km (10.7 times the average distance between the Earth and the Moon, or 2.75% of the average distance between the Earth and the Sun), at about 10.30 am GMT on Friday 24 June 2016. There was no danger of the asteroid hitting us, though had it done so it would have presented a considerable threat. (441987) 2010 NY65 has an estimated equivalent diameter of 94-300 m (i.e. a spherical body with the same mass would be 94-300 m in diameter), and an towards the upper end of this range would pass through the atmosphere and directly impact the ground with a force of about 1110 megatons (about 65 300 times the explosive energy of the Hiroshima bomb), causing devastation over a wide area and creating a crater about 4.6 km across, and resulting in global climatic problems that could last for decades or even centuries.

The argument for California to make a Colorado River deal

Inkstain (John Fleck) | 28 June, 2016
The trick now is for the three U.S. states sharing the Colorado River's water downstream of of Lake Mead - Nevada, Arizona, and California - to negotiate some sort of a deal that reduces their collective take on the river. That's trick one. Trick two is for state negotiators to then sell the deal back home to sometimes recalcitrant local water agencies that take a dim view of giving up water.

Approach to Titus Canyon: To Red Pass

Looking for Detachment | 28 June, 2016
It looks to me like you can see Quail Rock from White Pass!We've gone over White Pass--btw, here's a gigapan looking west from White Pass--and we've gone across the flats in the east fork of upper Titanothere Canyon. The road has become a fairly normal dirt road, and although it's still a little narrow, there are places to pull over, or pass, if you happen to be traveling faster than someone ahead of you--although by this point on the road, there is plenty to look at, everywhere, all around, so going slow behind someone (back far enough not to eat any of their dust) is an acceptable option. All through this section, until about the unnamed pass between the east and west forks of upper Titanothere Canyon, the age of the rock formations is Cambrian to the south and Tertiary to the north. The unnamed pass is marked by "Gate" and a gate symbol on the USGS topographic map of the area (USGS TNM 2.0 Viewer)--not that I noticed a gate.

“Dunbar marble” at Barns Ness, Scotland

Mountain Beltway | 28 June, 2016
Thanks to the website ScottishGeology.com, run by Angus Miller, I learned of Barns Ness, a Mississippian-aged limestone fossil site on the shore not far from where we are staying at Dunbar. We ventured out there on Saturday afternoon, in search of fossils.

The Hawai'i That Was: How Can the Biggest Mountain in the World Stay So Hidden?

Geotripper | 28 June, 2016
Mauna Loa from the Mauna Kea Road near the Onizuka CenterThe answer is easy: clouds. This whole post is a temper tantrum, a tantrum that resulted from the fact that we were on the Big Island of Hawai'i, the site of the biggest mountain on planet Earth, for nine days a few weeks ago. Despite repeated opportunities, my students never had a clear view of Mauna Loa, the volcano that covers more than half of the island. It was a rainy stretch of weather, so the best we ever got were brief peeks, kind of like watching an old-fashioned feather boa dance. So in response, I've drawn from the Geotripper archives to find pictures of Mauna Loa from earlier trips. Very sunny trips.
