Here are a few new images I’ve been working on with my home-based Magnify2 imaging system from GIGAmacro. Archean basement complex gneiss from the Gallatin Range of Montana: [gigapan id=”185543″] Link (If this looks familiar, that’s because one of the samples I imaged with the Photoscan 3D modeling technique and published on Sketchfab the week … Read more
Here are three more of my Photoscan-generated, Sketchfab-hosted 3D models of rock samples: Mud cracks in Tonoloway Formation tidal flat carbonates, Corridor H, West Virginia: Diorite from the eastern Sierra Nevada of California: Vein cross-cutting foliated & lineated gneiss, Blue Ridge basement complex, Virginia:
Here’s a great book about one family’s efforts to eat as locally as possible for a year, sort of. Whether or not they’re evangelical enough in their southwest Virginia locavory (I would have made the same call with regard to olive oil and coffee!), Barbara Kingsolver and her family definitely are certainly inspiring. Their efforts … Read more
Join Callan for a virtual field trip, as he shares dozens of photos from a recent ‘field review’ of a new geological map in Virginia’s Valley & Ridge province. Highlights: graptolites, trace fossils, geopetal structures, folds and faults.
Explore a series of spherical photos taken on a field review of a new geologic map in western Virginia.
It’s that time of the year – a time to state my “yard list” tally for the previous year. I have been posting this list every year since I moved to the Fort Valley: 2012 (39 species) 2013 (51 species) 2014 (58 species) In 2015, we had 65 species of birds spotted and definitively identified … Read more
New LiDAR imagery for the Fort Valley reveals bedrock structures and subtle aspects of fluvial geomorphology.
Ladies and gentlemen, I give you… The Friday fold: This beauty came to my attention on Monday, when I was lucky enough to go on a field trip with my friends Leigh and Mary. They are founding members of our local informal geology club, and we have been meaning to take a Cedar Creek field … Read more
As part of my work on the GEODE project, I’m always looking for good imagery to teach key concepts in geoscience. One important concept that I’ve been thinking about lately is the principle of relative dating on the basis of inclusions. Just as you can’t bake a loaf of raisin bread without already having raisins … Read more
My friend Barbara am Ende sent along this lovely image of a dike in Colorado: Here’s the site. You can see the dike in Google Earth. Dikes are fractures, filled with molten rock, which then cools and solidifies, sealing the crack shut. In this case, once it got uplifted to Earth’s surface and exposed, the … Read more
