Happy Friday – it’s the end of a very busy week for me, and I hope you too are looking forward to a fun and rejuvenating weekend. Here’s your Friday fold – like last week, a guest submission from Joe Kopera: Wowzers; that’s a looker! What are we looking at here? Joe writes: This photo … Read more
It’s Friday, so in search of an appropriate fold, Joe Kopera leads us to the top of New Hampshire’s Mt. Monadnock. Bonus: boudinage!
This is the second Andrea Wulf book I’ve read in the past month. It’s a biography of a great naturalist and popularizer of science and travel writing, who at the same time is largely forgotten in the modern English speaking world. Alexander von Humboldt’s intellectual impact is vast, Wulf argues, leading to everything from Darwin’s … Read more
I just finished an interesting book with a provocative title. How to Clone a Mammoth, by Beth Shapiro, is a readable, sober assessment of de-extinction, the idea of bringing back extinct species through a variety of techniques.

The British Geological Survey just came out with a new video on Siccar Point, featuring some excellent drone video of the site (in very good weather!). In addition to the unconformity, one of the things you will appreciate about the video is an excellent end-on view of a plunging synform exposed just above waterline: You’ll … Read more

All … Read more

A couple of weeks ago, before a series of snowfalsl altered my daily work routine in a destabilizing way, I took a walk through the braided floodplain / gravel fan of Passage Creek, where it exits the Massanutten Mountain system near the state fish hatchery. There, no longer restrained by the steep walls of quartzite, … Read more
Probably the most important book I ever read was Edward Abbey’s Desert Solitaire. It opened my eyes to a passionate, unapologetic way of living in the world, of embracing visceral experience of the natural world. It spoke to my heart in an authentic way, and changed my world view permanently. I was in college then. … Read more
Check this out: It’s a sample of the Reynolds Limestone, a member of the Mississippian-aged Mauch Chunk Formation, chock full of gastropod fossils. The image here is a 3D model made with Agisoft PhotoScan, a 3D model rendering program. The only input was a series of ~32 photos taken of the sample at various angles … Read more
