Behold the West. This is the frontispiece to a scientific report, the Report on the geology of the eastern portion of the Uinta Mountains and a region of country adjacent thereto – with atlas, by John Wesley Powell and Charles Abiathar White. White knew about rocks and fossils; Powell published plenty on Native American languages and myths. The Uintas are, to this day, a high wilderness area that aren’t much like the rest of the Rockies. Very tall. Sculpted by glaciers. Running east-to-west. The highest point in Utah is part of this range. Must’ve made for quite a survey.

ABSTRACT: First, let me say that this was done on time, even early. It started as a jokey thing I was singing to my son while he was watching me play guitar on the couch, and I decided what the hell. They call it “playing” music for a reason. (I guess if I spoke …
In 1775, Pennsylvania Magazine wanted its readers to be up to date on the very latest in technological advances, including this machine for… well, it seems to be some kind of a caisson for dredging harbors, more than something that “cleanses docks.” Anyway, it’s very impressive, this American ingenuity.
From the device’s description: The machine consists of a horse-drawn crane on a boat with a crane and shovel. A man is shown operating the shovel. Includes a detail of …

SONG: “Kavachi”. [Download] ARTIST: grant. SOURCE:Based on “Deep-Sea Cameras Reveal a ‘Sharkcano’”, National Geographic Explorers’ Journal, 9 July 2015, as used in the post as used in the post “Live Sharks Discovered Inside A Live Volcano.” ABSTRACT: There’s nothing I didn’t like about the process of writing this. If I was influenced by anyone in the making of this song, I guess it was The Residents, although the basic structure of it was unabashedly ripped off… myself. For about, oh, 15 years or so, I’ve had this vision of Devo doing a cover of a particular Doors song. It’s never going to happen. So I just stole that cover and rewrote it to have words about a sharkcano. Sharks. In a volcano. Filled with acid. Nearly everything you hear here is synthetic, except the main drum beat, which is me beatboxing into a pair of headphones, and the solo, which is a pair of sound […]
The New Yorker paints a pretty vivid seismic picture of the quake that some scientists say is due to rip the Pacific Northwest in two: Most people in the United States know just one fault line by name: the San Andreas, which runs nearly the length of California and is perpetually rumored to be on the verge of unleashing “the big one.” That rumor is misleading, no matter what the San Andreas ever does. Every fault line has an upper limit to its potency, determined by its length and width, and by how far it can slip. For the San Andreas, one of the most extensively studied and best understood fault lines in the world, that upper limit is roughly an 8.2—a powerful earthquake, but, because the Richter scale is logarithmic, only six per cent as strong as the 2011 event in Japan. Just north of the San Andreas, however, lies another fault line. Known […]
National Geographic reveals an ecosystem my 10-year-old son might have dreamed up. It’s all lava, acid and sharks. Inside the cauldron of Kavachi is a “sharkcano”: “Absolutely, we were scared,” says [Brennan] Phillips, a National Geographic Society/Waitt Grants Program grantee. “But one of the ways you can tell that Kavachi is erupting is that you can actually hear it—both on the surface and underwater. Anywhere within 10 miles even, you can hear it rumbling in your ears and in your body.” No one heard rumbling, so they prepared to go right to the rim of the crater. … Even without such theatrics it’s a dangerous place though. “Divers who have gotten close to the outer edge of the volcano have had to back away because of how hot it is or because they were getting mild skin burns from the acid water.” So the team strategically deployed their instruments—including disposable robots, underwater cameras, and National […]
SONG: “How the Moon Began.” [Download] ARTIST: grant. SOURCE:Based on “Puzzle of Moon’s origin resolved”, Nature, 8 April 2015, as used in the post “Scientists: The moon was formed when Earth smacked her twin sister.” ABSTRACT: Once again, Allison said this was the story that needed a song, and she was right. At around the same time, I was listening to “Cruel Sister” and thinking about murder ballads, but somehow, this didn’t come out folksy at all. I mean, except that it’s about ancient sisters getting into some kind of deadly fight. And has finger picking in it. I also kind of set out to write a *gushi* again, but that didn’t happen either – it kept wanting to rhyme, and then slant or else kind of extend past the rhyme (what’s the name for when that happens? Cole Porter does it all the time…). The thing that sounds like an accordion, isn’t. It’s a […]
Nature has more on the research into the aformentioned artificial earthquakes: It’s the first thing that geologist Todd Halihan asks on a sunny spring afternoon at Oklahoma State University in Stillwater: “Did you feel the earthquake? My mother-in-law just called to complain that the house was shaking.” Halihan’s mother-in-law has been calling a lot lately. Fifteen quakes of magnitude 4 or greater struck in 2014 — packing more than a century’s worth of normal seismic activity for the state into a single year. Oklahoma had twice as many earthquakes last year as California — a seismic hotspot — and researchers are racing to understand why before the next major one strikes. … Oklahoma’s quakes have been linked to underground wells where oil and gas operations dispose of waste water, but mining, geothermal energy and other underground explorations have triggered earthquakes from South Africa to Switzerland. … Companies drill into the ground to extract oil and […]
Click to embiggen This is a handmade map from the construction of the Panama Canal, one of history’s greatest feats of engineering. Culebra Cut is where the project experienced massive landslides (is it fair to say some of them are still going on today? I think it is… it is). So the folks in charge of the dig, the Isthmian Canal Commission, got geologists down there to study how to move all that dirt out of the way without burying any workers and steam shovels and train cars. This is one section of the dirt-profile from AB Nichols’ notebooks. It’s labeled “Isthmian Canal Commission. Partial Geological Profile along axis of Canal in Culebra Cut, by A.B. Nichols and A. Raggi. 1910.” I found it in the Linda Hall Library Digital Collection.
Nature reports on a new way of looking at lunar formation that almost reads like a myth. The moon came to be when Earth collided with a near-identical sister planet: The ‘giant impact’ hypothesis, first proposed in the 1970s, suggests that the Moon was formed from the debris scattered when a Mars-sized planet slammed into the early Earth some 4.5 billion years ago. This fits well with what we know about the Moon, including its mass and lack of any significant iron core. But the theory also implies that the Moon is made up mostly of impactor material. Since lunar and Earth rocks have such similar compositions, this suggests that Earth and the planet that smacked into it resembled each other too. They would have needed to be sister planets, with a relationship much closer than that of any other planetary bodies we have studied in our Solar System.

Daily Beast has more on how 204 billion tons of melting glaciers have changed the way our planet’s gravity works: Between 2009 and 2012, the years for which GOCE was taking data, the amount of gravity in Antarctica decreased noticeably, corresponding to a lot of ice melt. From the point of view of artificial satellites or the Moon, Earth’s gravity is mostly a steady influence, a tug that doesn’t particularly depend on where the satellite is over Earth’s surface. However, mass is the source of gravity, so if the crust is thicker in one place than another—say, the Himalayas vs. the floor of the Atlantic Ocean—the thicker part will exert a slightly higher gravitational pull. … The authors of the new paper looked at GOCE and GRACE data for three Antarctic glaciers, and found they are losing approximately 185 billion metric tons (204 billion US tons) of ice each year for the three years of […]

Or a geosynchronous orbit, at least.
You might have heard, like many Discovery News readers, of the weird moving rocks of Death Valley – the ones with the long, curving trails behind them. No one’s ever seen how these huge boulders skate across the desert until now: The first witnesses to an enduring natural mystery are an engineer, a biologist and a planetary scientist who met thanks to a remote weather station. … Now, with video, time-lapse photographs and GPS tracking of Racetrack Playa’s moving rocks, the mystery has finally been solved. … agged plates of thin ice, resembling panels of broken glass, bulldoze the rocks across the flooded playa, the scientists reveal today (Aug. 27) in the journal PLOS One. Driven by gentle winds, the rocks seem to hydroplane atop the fluffy, wet mud. “It’s a wonderful Goldilocks phenomenon,” said lead study author Richard Norris. “Ponds like this are vanishingly rare in Death Valley, and it may be a decade […]
Nature offers one of the least comforting explanations for a mysterious hole in Siberia. It wasn’t from an asteroid or a rogue telephone-pole-installing crew. The 30-meter-wide crater was caused by methane – a flammable, stinky greenhouse gas – being released from melting permafrost: Over the past 20 years, permafrost at a depth of 20 metres has warmed by about 2°C, driven by rising air temperatures, notes Hans-Wolfgang Hubberten, a geochemist at the Alfred Wegener Institute in Potsdam, Germany. Hubberten speculates that a thick layer of ice on top of the soil at the Yamal crater site trapped methane released by thawing permafrost. “Gas pressure increased until it was high enough to push away the overlying layers in a powerful injection, forming the crater,” he says. Hubberten says that he has never before seen a crater similar to the Yamal crater in the Arctic. Larry Hinzman, a permafrost hydrologist at the University of Alaska in Fairbanks […]
Nature shares satellite data that shows not only lakes, rivers and reservoirs shrinking across the whole U.S. Southwest, but even water underground is going away: To track groundwater losses, researchers used data from the Gravity Recovery and Climate Experiment (GRACE), a pair of satellites operated by NASA and the German Aerospace Centre (DLR) that measure variations in the gravitational pull of Earth. The team found that from December 2004 to November 2013, the Colorado River basin — which supplies roughly 40 million people in seven US states — lost roughly 65 trillion litres of fresh water. To determine how much of that was groundwater, they subtracted out water lost from surface reservoirs and soil. The result was more than 50 trillion litres, roughly 1.5 more than the maximum capacity of the United States’ largest reservoir, Lake Mead in Nevada and Arizona. “It was way more than we ever thought,” says study co-author Jay Famiglietti, a […]
