Unlike the prospectors bound for California鈥檚 gold fields in 1849, 新加坡六合彩开奖直播鈥檚 senior Earth Sciences students were not lost when they arrived in Death Valley early this May.
Camping in four different locations 鈥� the Mormon Mountains in Nevada, Death Valley National Park, Panamint Valley, and the White Mountains in California 鈥� the group of 21 students, three teaching assistants, two directors, two Nunavut Arctic College students, and one camp manager braved remarkable locations over the course of nearly a month for a one-of-a-kind field school.
鈥淓xperiential learning is our focus,鈥� says co-director . 鈥淭his is our big adventure for the students.鈥�
This field school, unique in Canada, had previously been set up as a field trip and geo-tourism course, where senior students would travel to very exotic places every year. They only lasted 10 or 12 days, though, and it was common for students to stay in motels rather than camp.
鈥淲e wanted a longer experience to mimic the professional world for our students, whether it is academic, government or, more likely, industry,鈥� says Young. 鈥淗alf of our goal with this field school was mimicking that camp life, that building of a community to achieve a common goal.鈥�
The team of students and staff completed intensive and rigorous mapping projects, reports and field work, all the while growing accustomed to managing camp life 鈥� from cooking to cleaning to making sure the camp was running efficiently.
鈥淚t鈥檚 kind of how you would live up North when working,鈥� says student Rachel Milligan. 鈥淭hese are the only people you are going to see for a month and you have to work together.鈥�
The field school was focused on four major themes: regional stratigraphy, the idea of looking at geology through time; compressional tectonics, the study of mountain building events; extensional tectonics, the development of big valleys such as Death Valley; and strike slip tectonics, such as the San Andreas Fault.
鈥淲e got to take everything we did up to now in school and actually see it and apply it,鈥� says student Taylor Campbell.
Locations that give the best examples
Co-directors Mike Young and were able to take advantage of the length, the location and the climate of the field school to provide the very best geological examples聽 for the students.
鈥淭he weather is so dry that we could make a plan and stick with it. We could work every day and never have to delay a project because of rain,鈥� says Young.
In Nova Scotia and much of Canada, accessing great geological examples is much more challenging, since trees, grass, or soil cover 90 per cent of the rock outcrop. Geologists often have to hike along rivers or coasts to find exposed rock surfaces. Weather also usually plays a factor in Canada. This was not the case in California, Death Valley and Nevada, as the field school worked in areas that had nearly 100 per cent exposure in every area.
鈥淓xposure was important for us,鈥� says Milligan. 鈥淭he whole tectonic history and stratigraphy, the layers of rock, and the history of how they were deposited and why it is so easily seen are available in areas of great exposure like Death Valley.鈥�
聽鈥淎nother thing we don鈥檛 have in most of Canada is active tectonics,鈥� says co-director Dr. Gosse. 鈥淭he students actually stood on faults that ruptured within centuries鈥攖hey stood in areas that are actively seismic.鈥�
鈥淚t鈥檚 unfortunate that we didn鈥檛 feel an earthquake,鈥� says Campbell. 鈥淏ut if we'd had seismometers with us, we would have measured 2 and 3 magnitude earthquakes all around us.鈥�
On one of the last days of the field school, the students even stood on a 600-year-old volcano with magma that had come near the surface in 1984.
鈥淣ow the students know the story of the other side of the continent and now they can compare and contrast how continents evolve through time,鈥� says Young.
The importance of mapping
The mapping projects were designed to give students an appreciation of how much work goes into making a geological map.
鈥淲ith making a map comes interpretation,鈥� says Dr. Gosse. 鈥淭he students had to ask themselves what caused what they are seeing鈥� they had to look for smoking guns. They had to look for a relationship that would allow them to rule out one hypothesis over another and that鈥檚 what they did multiple times every day for each project.鈥�
A geological map is much more complicated than your regular road map. All sub-fields of geology rely on the very basic and complicated information portrayed in a map sheet such as geological features including faults, folds, foliation and lineation. They are shown with symbols that convey the often complicated three-dimensional geometry of the various rocks in the area. Even rock units and strata are shown by color or symbols to indicate where they are exposed at the surface.
鈥淪ome students may never map again and do fieldwork, but they will have this experience under their belt,鈥� says Young. 鈥淭hey will now have the confidence to do something as challenging as this field school. I think it will set our students apart for the future.鈥�
A spectacular experience
Both students agree that this field school was an amazing experience.
鈥淢ike and John are so passionate about what they do and they give you the motivation to want to be like that,鈥� says Campbell.
Special thanks
The Department of Earth Science wanted to express their thanks to the sponsors who made this new one-of-a-kind field school possible through their generous support.
Sponsors:
(CNGO), , , , , (PDAC), (CSEG), (GAC), and the (DSS).
Special thanks to the Canada Nunavut Geoscience Office (CNGO) who provided funding for the camp manager. CNGO also sponsored Patricia Peyton and Candice Sudlovenick, two students from the Environmental Technician Program at the Nunavut Arctic College in Iqaluit, (shown in the and a ), amounting to $16,000.
