Three new videos from Montana
I spent several enjoyable weeks in Montana last month, and shot some new video content there for my YouTube channel. Here are three videos that may be of interest to readers of this blog:

On his way to get his COVID vaccine, Callan visits a new outcrop showing folded and faulted strata of the Neoproterozoic Lynchburg Group.
A submarine slump complex at Sandy Cove, Newfoundland
Traveling in Newfoundland, Callan visits a seaside outcrop showing a Proterozoic submarine slump complex, overprinted by tectonic cleavage and weathered by the sea.
Slump palimpsest, Corridor H
There’s a section of my favorite road, the lovely nowhere-to-nowhere Corridor H, that seems to be having some issues with slumping. I noted this in November of 2015, and I return to the topic today. Here’s a look at the slope, with old drainage “French drains” installed, and a fresh scarp transecting it just the … Read more
Peat slide!

Firsthand reports from Canoa, Ecuador after the quake
Callan’s mother-in-law lives in one of the most strongly-shaken regions of Ecuador. Here, she and her boyfriend recount the experience of the earthquake Saturday night and its aftermath. Includes 8 photos from the scene.

(The left half of the image is moving down relative to … Read more
A rock slide and a protalus rampart (?) on the trail to Helen Lake
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?
Bell Canyon’s Permian submarine landslide
What are these Border to Beltway students up to?… Clearly, they are all immersed in their field notebooks, sketching away. This was in March, in west Texas. There must be something worth drawing at this road cut… A clue can be seen on the wall of rock behind them. There, you can find features such … Read more
