Longtime reader and frequent contributor Howard Allen has three images to share with us today. Let’s see what he’s got…
Oh my. What is that?
West ridge of Mount Evan-Thomas, Opal Range, Peter Lougheed Provincial Park, Alberta. View looking south across Grizzly Creek at structural features (yellow boxes outline detail images to highlight key features, shown in subsequent images). Rocks are Carboniferous (Mississippian) carbonates. Location is 50.7660, -115.1259. Photo taken in 1981.
Oooh! Exciting! Let’s zoom in.

Great stuff. Thanks so much for sharing.
Thanks again for your contributions, Howard. I’m hoping we can see this site for ourselves this summer!
