This is the fourth of several guest posts that appear here this week, all written by students who participated in this past summer’s Regional Field Geology of the Northern Rocky Mountains course. by Tony Robinson Old Dominion University [youtube=”www.youtube.com/watch?v=XTWNmUNbBBU”]
A few photos from the Canadian Rockies illustrated the characteristic “look” of glacial striations. Callan also demonstrates how they can be used for outright tomfoolery.

Yesterday, I showed you a scene of geologists (including me) clustered around some (presumably interesting) outcrop. I asked what you thought we might be looking at. Howard Allen, a denizen of this part of the globe, immediately identified the scene as that of the downstream end of the Athabasca Glacier. Several people guessed that we … Read more

We picked a rough couple of days for hiking – We got a lot of Canadian Rockies precipitation out there: … Read more
Another batch of out-the-airplane window photos from March, on my flight from Reno, NV, to Minneapolis, MN. I looked out the window and saw a form that seemed familiar…. A slightly higher-contrast exposure: I was focused on that asymmetric mountain range in the distance. Is that the Tetons? And Jackson Hole to their east? I … Read more
More photos from the flight from Reno to Minneapolis in March. The photos in today’s post come from the air above the Dakotas and Minnesota. First up: a series showing the intersection of natural patterns (presumably related to ground moraine) and the palimpsest geometric regularity of anthropogenic designs: Are these kettles? A close up look … Read more
Picking up from the astonishing first couple of outcrops we saw of strained Seine Group metaconglomerate from the boundary between the Wabigoon and Quetico sub-provinces of the Superior Craton, our group moved on down the road. It was lovely clear fall weather near Fort Frances, and shockingly warm. Our third stop of the morning was … Read more
