A guest post from longtime friend of Inkstain (and friend of the Colorado River) Karl Flessa.

In the classic Monty Python sketch, a customer returns to the pet shop where, just 30 minutes ago, he purchased a parrot. ...
I vividly remember attending the 14th International Meeting on Organic Geochemistry in 1989 in Paris. I witnessed a presentation by John Hayes during which he introduced both a conceptual framework for interpretation of stable carbon isotopic compositions (?13C values) of biologically-derived compounds (biomarkers), as well as a novel analytical approach to measure ?13C values of individual compo…

As autumn gives way to winter across the Arctic, the ground doesn't immed...
Remember a time before The Franchise had a near-monopoly on movie dinosaurs? Me neither. To avoid any references to the Crichton and Spielberg-spawned behemoth, you'd have to travel in time all the way back to the 1980s. And that seems like as good...
There is an exchange between two characters in Tom Stoppard's mind-bending play Arcadia (1993) that captures in a clever way the essence of science. In Act Two, Scene VII, two characters in the present day on the Coverly estate are discussing even...
I'm prepared to predict, even two weeks before it's over, that summer 2026 will end up as England's hottest on record. Central England Temperature (CET, data available here) records the average temperature over a large region of central England...
(I wrote this post eleven months ago, but for some reason didn't get around to posting it. Well, now I have. Not now, when I'm writing this sentence, but now, when you're reading it.)
Welcome to In the News: A Geomorphologist's Perspective! The intent of this series is to explore the geology and geomorphology of places that are currently in the news.
Adams Point, the peninsula on Lake Merritt that's now the heart of Lakeside Park, was always open space, but never empty. Activity went on there from Oakland's earliest days. When a long-forgotten structure was discovered at Adams Point in 1893, the story was in all the papers for almost a week. After that it was forgotten again. Until this post.
When you picture the western Mediterranean, you likely imagine sun-drenched beaches, terracotta roofs, and bright blue skies. But has it always been this sunny?
Since early March a previously obscure waterway between Iran and Oman
that very few people could name has become the subject of daily reporting
around the world after Iran closed it as a response to the attack on Iran
by the United ...
Fish gular plate fossil found in the Jeffersonville Limestone. It dates to the Middle Devonian Period. Specimen is from the Barbara
Conkin collection and was probably found in Clark or Floyd County,
Indiana USA. Thanks to Kenny for the image. Field...
My Rio Grande thinking is almost entirely about the bits in New Mexico, but this, happening now at Big Bend, on the US-Mexico border, is worthy of note:
Bulldozers have begun plowing up ground at the mouth of Big Bend national park's famed Sant...
This fossil is a Maturifusus (J. Szabó, 1983) gastropod fossil found in the
clay pits at Buttenheim located in the state of Bayern (Bavaria),
Germany. I think it is located in the Lias lithostratigraphic unit which
would date to the Jurassic. Fie...
Lake Lahontan (pale gray) is "a large lake which flooded a number of the valleys of northwestern Nevada at a very recent geological date, but now has passed away."Last May, I visited Lake Lahontan in the company of pioneering geologist Israel Charles...
