A hike to Helen Lake, Banff National Park, Alberta, brings your intrepid geoblogger face to face with a fresh landslide and a curious landform parallel to the glacial valley. Is it a pro-talus rampart?
Want to see something cool? Itty bitty stromatolites… like baby’s fingers! There’s a big weathered-out stylolite at the base of this stromatolite-bearing layer, too. These elfin stromatolites are part of the boulder in the lower left (foreground) of this GigaPan, taken at the Icefields Center parking area in Jasper National Park, Alberta: [gigapan id=”159489″] … Read more
Let’s journey to the Cretaceous today, to see sandstones, shales, and even some coal strata that have been folded during the eastward thrusting that built the Canadian Rockies. Here’s the same fold, in context, shot in GigaPan on a different day, from a different angle. Can you match it up? [gigapan id=”159471″] link Ben Gadd … Read more
Back in 2011, when we were still living in D.C., Lily and I made a hiking trip out to Buzzard Rocks. It was a destination. Now that I live out here in the Fort Valley, I see Buzzard Rocks all the time, and I love it. It’s such a cool feature – a spot on … Read more
Silurian aged mud cracks feature small lensoidal features: are they casts of ancient gypsum crystals?
It’s been a long time since I’ve shared some of the work of our GigaPan making team. Here are some of the highlights from the last five months of work… In the images below, see if you can find (a) ten thousand fusilinid forams excavated by Texas ants, (b) Devonian trace fossils in black shale, … Read more
Three folded sandstone slab-blobs will serve as today’s Friday folds. Meet the ploudins!
The Friday fold is an outcrop in Yoho National Park that showcases differences between buckle folding and passive folding.
