The Association for Women Geoscientists (AWG) published their first geology field trip guidebook in late 2016 and it is now available for sale to the general public. This guideboook is a collection of geology road logs, associated geological information, and local cultural history of areas within the Canadian Rockies and the Alberta Badlands. The following text is a brief summary of the guidebook:
“TECTONICS, CLIMATE CHANGE AND EVOLUTION – SOUTHERN CANADIAN CORDILLERA: Road Log and Accompanying Narratives From: Calgary – Lake Louise – Icefields – Field – Revelstoke – Fernie -Dinosaur Provincial Park – Calgary”, published by the Association for Women Geoscientists, 2016.
This field trip guidebook is written by Katherine J.E. Boggs and Debra L. Hanneman, and edited by Janet Wert Crampton and Stephanie Yager. It is the AWG’s first fully published field trip guidebook and is a field-tested guide from their two-week 2014 field trip through the Canadian Rockies and Alberta’s Badlands area.
The guidebook is a 209-page geology tour through many of the well-known parts of the Alberta Canadian Rockies, including the Front and Main Ranges of the Canadian Rockies and the Columbia Icefields. The Burgess Shale’s Walcott Quarry, the Okanagan Valley vineyards, and the Rocky Mountain Trench are trip highlights for geo-tours in British Columbia. The field trip guidebook ends with a geology tour of the Crowsnest Pass area on the British Columbia/Alberta border, and with field stops in Alberta’s Dinosaur Provincial Park and at the Royal Tyrrell Museum, Drumheller, Alberta.
The field guide is printed on double-sided 8.5″ x 11″ pages with the guide cover on 100 lb paper and the text on 80 lb paper. It has black wire-o binding and a clear acetate front and a black acetate backing for improved field durability. The guidebook’s cost is $55 USD (which includes shipping), and can be purchased at the AWG online store or by phoning the AWG main office at 303-412-6219.
The Middle Cambrian Burgess Shale and its contained fossils are legendary to earth scientists. These fossils are by far the best record of Cambrian animal fossils. The importance of the Burgess Shale fossils is also linked to their excellent preservation. The fossils include many soft bodied animals in addition to those with hard parts – an extremely rare occurrence for fossil assemblages.
I finally hiked to the Walcott Quarry on Fossil Ridge near Field, B.C., last year, just to better understand the context of the Burgess Shale. It was well worth the effort (it is a long, and as other hikers phrased it – a gut-busting hike). Before my Walcott Quarry hike, I’d read that Kootenay National Park just started hosting hikes to Burgess Shale type faunas (BST) in the Stanley Glacier area. It only took a good dinner and a beer after the Walcott Quarry hike to decide that I’d do the Stanley Glacier Burgess Shale hike.
Stanley Glacier BST fossils (approximately 505 million years in age) are about 40 km southeast of the Field, B.C. (Yoho National Park) locales. Recent work in both the Marble Canyon and the Stanley Glacier areas of Kootenay National Park yielded noteworthy additions to understanding the BST fossils and their depositional environments. BST fossils found in the Marble Canyon area include 25 new species of organisms; 8 new species are now recorded for the Stanley Glacier BST fossils. Of more interest to me (being a sedimentologist), is that the depositional environment in the Kootenay National Park area differs from that of the Field, B.C. area. Although the Burgess Shale fossils are found within the Stephen Formation in both areas, there is a marked difference in this rock unit from one area to the other area. Around Field, B.C., the Stephen Formation is the “thick or basinal” (about 276 to 370 meters thick) Stephen and it resulted from deposition at the base of the older Cathedral Formation Escarpment (a submarine cliff) via turbidity flows. In the Stanley Glacier area, the Stephen Formation is relatively “thin” (about 33 meters thick) and is probably the result of deposition at the distal edge of a marine platform (Caron and others, 2010; Gaines, 2011). The stratigraphic placement of the Burgess Shale rock units also differs from the Field, B.C. area to the Stanley Glacier area. Based upon the presence certain trilobites and stratigraphic evidence (Caron and others, 2010), the “thin” Stephen Formation at Stanley Glacier is stratigraphically above the Field, B.C. Burgess Shale localities.
With that small bit of Burgess Shale background, I’ll get back to the actual hike up the Stanley Glacier valley to the Stephen Formation talus slopes and outcrop. The hike is hosted by Kootenay National Park and is about 10 km for the round trip. The elevation gain is about 450 meters. The first part of the hike is through glacial material and a fire-swept lodgepole pine forest. Forest fires burned through this area most recently in 1968 and in 2003. Luckily for paleontologists, the fire bared many slopes and definitely helped in locating BST fossil beds. A little more than halfway through the hike, one breaks out of the trees onto the talus slopes of Stanley Glacier’s valley. The hike continues over the talus slope to a very large boulder. Several BST fossil specimens are locked in a box kept behind this boulder. Our guide gives an informative talk about the lockbox fossils and we have much time to pick around the talus slope for more fossils.
In 1989, an expedition party from the Royal Ontario Museum (ROM) located fossils from Stephen Formation talus in this area (Rigby and Collins, 2004: Sponges of the Middle Cambrian Burgess Shale and Stephen Formations, British Columbia; Royal Ontario Museum Contributions in Science 1: 1–155.). Caron and others (2010) also document that some of their fossil assemblage material came from the talus slope, so it’s worth some time to look around (Caron and others, 2010 GSA Data Repository).
Stanley Glacier BST shelly fauna includes characteristic Cambrian taxa such as hyolithids, brachiopods, and trilobites. Soft-bodied BST creatures such as the necktobenthic or nektonic arthropods and proto-arthropods Stanleycaris hirpex n. gen., n. sp., Tuzoia retifera, and Sidneyia inexpectans also are part of the BST fauna. Trace fossils are plentiful on some bedding surfaces. These include trails, shallow burrows, and arthropod trackways.
The AWG 2014 Canadian Rockies Field Trip took place from August 28 to September 7, 2014, with a Calgary-area geology pre-trip for early arrivals on August 27. The main part of the field trip commenced with a mid-morning departure on the 28th from Calgary, and we all headed west along Canada Highway 1 to Lake Louise. After spending two days in the Lake Louise area, we drove north to the Columbia Icefields. A few of us continued further north the next day, on an side trip to Jasper. From the Icefields we toured south to Field, British Columbia, over to Revelstoke, and ended our British Columbia time in Fernie. We then drove east, back into Alberta, and spent time at Dinosaur Provincial Park near Brooks and at the Royal Tyrrell Museum of Palaeontology in Drumheller. The trip ended with our group once more back in Calgary, Alberta.
There were 22 people as full-time field-trippers and two more people on the trip during the Icefields to Field, B.C. part of the trip. Two of the full-time trip participants were students and one of the additional, part-time trip participants, was a student. All of the students on the field trip are from Mount Royal University in Calgary and are students of our field trip leader, Katherine Boggs. Paul Hoffman and Mindy Brugman also helped out for a day or so during the trip. Marcia Knadle and Debra Hanneman did the trip budget and logistics. We had a great field trip guidebook, thanks largely to Katherine Boggs’ efforts. The field trip guidebook, “Tectonics, Climate Change, and Evolution: Southern Canadian Cordillera” will be on sale at the AWG online store soon.
The 2014 AWG Canadian Rockies Geology Field Trip did actually end last Sunday (9/7) and we did indeed make it back to Calgary largely unscathed. As many of you probably know, when lodging amenities state that WiFi is included, it most likely means that one can check email – not post blogs with photos of any size, or maybe not even post blogs without photos. Anyways, we did run out of somewhat viable WiFi in our remaining travels. So – this blog is a brief summary of what other adventures awaited us on the road from Revelstoke, B.C. to Fernie, B.C., and then eastward to Dinosaur Provincial Park near Brooks, Alberta, and finally to the amazing Royal Tyrrell Museum at Drumheller, Alberta.
The Association for Women Geoscientists’ 2014 Canadian Rockies geology field trip is fast approaching. The trip starts and ends in Calgary, and runs from August 28th through September 7th, with pre-trip hikes around the Calgary area on August 27th. Because the trip geology will be so spectacular and many people wanted to go, but just did not have the available time to do so, we decided that we will do blog postings during the trip whenever we have access to wifi (which should be most of the field trip nights). And – if anyone is really interested in the trip after following our travels, the field guidebook will be on sale at the AWG Online store after the trip.
To better follow our postings, I thought it would be helpful to give a brief run-down of the trip itinerary so that everyone knows what to expect for our travels:
August 27th – Fish Creek Park in Calgary – looking at the 2005 and 2013 Calgary flood features and constraining the boundary between the Laurentian and Cordilleran Ice Sheets.
August 28th and 29th – Trans-Canada Highway to Lake Louise for classic transect through Foothills to Main Ranges of Foreland Fold and Thrust Belt.
August 30th and August 31st – Icefields Parkway: Peyto Lake, Saskatchewan Glacier, Athabasca Glacier stops just to name a few. We also will have Paul Hoffman with us, so we will have good discussions on topics like “snowball earth”.
Registration is now open for the Association for Women (AWG) Geoscientists 2014 Canadian Rockies Geology Field Trip. All registration information and associated forms are posted on the AWG website at: AWG 2014 Field Trip.
