Deglaciation of the NW Laurentide Ice Sheet and opening of the Mackenzie valley
Principal Investigator: Froese, Duane G
Licensed Year(s): 2019 2018
Summary: In this project, the research team aim to improve the chronology of the retreat of the Laurentide Ice Sheet from the eastern foot of the Mackenzie Mountains and the Mackenzie River valley that began around 14,000 years ago, and to gain better understanding of the dynamics of how the ice left the region and development of large lakes that occupied the valleys. The team will attempt to quantify the ...


Timing of deglaciation of the Mackenzie River valley 60-67 dg N
Principal Investigator: Froese, Duane G
Licensed Year(s): 2015
Summary: The objective of this research project is to search for glacial erratic boulders left behind by the retreating ice sheet margin and collect samples for cosmogenic exposure dating. In order to obtain time constraints on the deglaciation ages in the Mackenzie River valley the research team will apply Be-10 cosmogenic exposure dating. The research team will aim to collect samples in a series of v...
