It's an old cliché among geologists that humans will leave their mark in the rock record of the future as a layer of petrified garbage, and stratigraphers will call our age the Broken Glass Epoch. Paul Crutzen put it more formally in 1990 with the proposal to name a new geologic age called the Anth ...

The BBC will start running its colossal series " How Earth Made Us " next month. But a slight preview is available on photographer Paul Williams' blog Iron Ammonite , where he recounts his experience filming in the Cueva de los Cristales, the Mexican mine chamber where preposterously large gypsum cr ...

In 1978 two men came upon a large bone in a riverbank north of Waco, Texas, that local experts identified as the remains of an Ice Age mammoth . The site later yielded the remains of a whole nursing herd, which had perished during a flood some 68,000 years ago. This weekend the Waco Mammoth Site ope ...

The International Commission on Stratigraphy has done a lot of work this year, and the world-standard geologic time scale has changed enough for me to update everything to match the new divisions, dates, and map colors. Start with the high-level eras and eons scale and poke around the last 4 billion ...

California is full of wineries and faults, but only one active winery sits on an active fault. Last weekend's Wall Street Journal visited the DeRose Winery and posted photos and a video to go with the story. The winery is in the Cienega Valley in the creeping section of the San Andreas fault. Contin ...

Here is a great looking world map which shows the distribution of continental  basalts (a) and ophiolite complexes (b). Ophiolites are slices of the earth' s oceanic crust and upper mantle that have been exposed on land by tectonic forces. They are found along ancient and modern convergent plate se ...

The December issue of Nature Geosciences has a series of articles on carbon sequestration. The editorial is behind a pay wall but the Correspondences and Commentaries are open access. There is an interesting article on the geopolitics of geoengineering in which the author Philip Boyd raises the con ...

For a scientist studying climate change, “eureka” moments are unusually rare. by Dr. Nitish Priyadarshi photo credit:http:// boojum.as.arizona.edu In 1938, British meteorologist Guy Stewart Callendar made the first proper measurement of global temperature. He gathered data from weather stations ...

Way out of my normal range of coverage on here, but I did need to flag this up. Given just how scathing I am on the Musings about scientific reporting in the media, if noting else this is well worth praising. This is a massive editorial as published in a staggering 56 newspapers in over 20 languages ...

The lands to the east of the Sierra Nevada are barren. In the rain shadow of the High Sierra, the hills to the east are dry, mostly treeless, and to many people, not particularly scenic or beautiful. During my days as a graduate student at University of Nevada, Reno, I came to have a different view ...
