Over chai, elders told us about large serpents invading their village. A curse, they said. Only the correct prayers and purification rituals saved them, forcing the serpents to retreat deep into the forest. Some serpents remain trapped in the rock faces near the village, which was renamed Nagling (Nag means cobra..or more generically serpent). The picture below are the entombed serpents

Well, there we have it: the Carlin Canyon unconformity with the Humboldt River running nearly bankfull on April 11th of this year. Looking downstream, back toward the tunnels, we're actually still looking at the unconformity, but it's cropping out poorly on the slope below the tilted limestone beds of the Pennsylvanian-Permian Strathearn Formation. I went ahead and cropped the best photo

High levels of radioactive cesium remain in the soil near the Fukushima Daiichi nuclear power plant and these radionuclides have migrated at least 5 centimeters down into the ground at several areas since the nuclear accident five years ago, according to preliminary results of a massive sampling project being presented at the JpGU-AGU joint meeting in Chiba,

Using Google Earth for Earth Science Education

I am creating a series of Google Earth labs to use with my middle school Earth Science textbook Earth Science: God’s World, Our Home. For the most part, these labs could be used with other textbooks as well, though I do occasionally refer to figures or pages in my textbook. At this stage, I would love […]

Hi friends! Remember me? A new geology field guide has been posted on this website. This one gives you something to do while you huff and puff your way up through the 45-million-year-old Barlow Pass Volcanics on the Dickerman Mountain Trail. The mountain rises above the South Fork Stillaguamish Valley, and is reached by the

My GigaPan expedition has landed at Rathlin Island, north of Northern Ireland, within view of Scotland, for a few days. The beach on Church Bay is cobble-covered and steep, and the cobbles reflect the island’s geology, with some anthropogenic components thrown in for flavor: Link GigaPan by Callan Bentley But I was struck by these two cobbles, each showing a pervasively shattered breccia of chert: To me, that is not

A lot of geology involves glimpsing the ideal behind the real. As you look around Oakland, the Hayward fault isn’t easy to see without a bit of training. For this post, let me start you from the ideal. The process of faulting has very specific effects on the land that you can learn to look

Last week, I was in Iceland, driving around the country’s Ring Road and checking out its amazing geology with my family. We had a great time in particular exploring in the Lake Mývatn region, on the country’s subaerial expression of the Mid-Atlantic Ridge. Lake Mývatn itself is in a rift basin, peppered with a great variety of volcanic and hydrothermal features. One spot we enjoyed a short stroll was in

My friend Pradeep Sarkar died last Tuesday June 7th. He got up that morning and complained of shortness of breath. In a few minutes it was all over. He leaves behind a shattered family, a wife and a son, and a large number of stunned friends, colleagues and students. I met Pradeep when he joined the faculty at Fergusson College, Pune, during my second year B.Sc. He had a way with students
