Objective(s): The "Snow-Ball Earth" hypothesis states that the world ocean mostly froze over for millions of years near the end of the Proterozoic eon. The project team intends to test this hypothesis with stratigraphic and geochemical data from Neoproterozoic glacial and associated sedimentary strata in the Mackenzie Mountains in the NWT and Yukon.

Project Description: The research team will be based out of Norman Wells, and establish a series of fly camps in the research area between 1 July and 10 August. Travel to fly camps will be by helicopter; travel in the field will be on foot. Fly camps will be low impact, and will be occupied for less than 14 days. All human waste will be buried, and all non-burnable garbage will be packed out. Stratigraphic sections will be measured with hand-held scale bars. Small (fist sized) rock samples will be collected with a hammer. Samples collected will be returned to laboratory facilities for detailed analysis.
