… a brief glimpse of summer in the Rockies: [youtube=”http://www.youtube.com/watch?v=hbRx7W1nYUk”] Footage shot south of Blacktail Butte, in Jackson Hole, looking west towards the Teton Range, in Wyoming. July 2011. Gros Ventre River terrace in the mid-ground.
Northern Colorado’s route 287 connects Fort Collins, Colorado with Laramie, Wyoming. Along its length, it displays roadcuts into Archean-aged basement complex. Two of these outcrops are featured in this post: one metamorphic (mostly), and a second igneous (mostly), with some intriguing polka-dotted plutons.
You’re looking here at Mount Kidd, a peak in the Front Ranges of the Canadian Rockies that displays a tight anticline/syncline duo superimposed on the strata of the Rundle Group. Located on the west side of Highway 40, the Kananaskis Trail, south of the trans-Canada Highway, this mountain shows us what happens with Carboniferous-aged carbonates … Read more
Callan visits the Burgess Shale in British Columbia’s Yoho National Park on a guided tour. This photo-heavy post discusses the depositional setting of this world-famous Cambrian fossil deposit, the landscape along the hike, and (of course) the fossils themselves.
Callan embarks on an exhausting climb of a major summit in the Wyoming Bighorn mountains, a peak named in tribute of one of his geological heroes. Come join the trek to the top of Darton Peak!
Here’s one of the first things as you drive north from Chief Mountain in Glacier National Park, and cross the border into Alberta: The mountain in the middle is Crandell Mountain, and it looms to the north above the village of Waterton Lakes, but the lovely folds it displays are best viewed from a more … Read more
Our field class visited the Museum of the Rockies yesterday. Here’s the full team!
I just drew up a little checklist for the different formations my Rockies students will be seeing next starting next week out in Montana: The original black and white images (two columns on two pages) come from Self-Guided Field Trips Near Bozeman (1982), by Stephan G. Custer, Donald L. Smith, Molly Walker, and 1982’s crop … Read more
Yesterday, I asked for you to evaluate this rock sample of the Belt supergroup and tell me how many structures (both primary and tectonic) that you could identify in it. Thanks to everyone who participated in the discussion. Here’s my annotated copy of that photo for comparison:
Last summer, in Bonner, Montana on my Rockies field course, I took the students to see some nice exposures of Belt Supergroup strata on the side of the road. We were keeping our eyes peeled for both primary structures (i.e., patterns in the sediment that formed at the time of their deposition) and secondary, or … Read more
