Lava-eskers: Lava flows and subglacial ice tunnels collide
Mentor: Dr. Steve Quane
I study the question: How is the earth shaped by water? Southwestern British Columbia is a place of immense geological diversity. While much of the area has been investigated, many features have yet to be described. The lava flows near the Cheakamus River were hypothesized to be lava-eskers by W. H. Mathews in 1958. Lava-eskers are lava flows that erupt into subglacial meltwater channels beneath a glacier and cool in unique ridges mirroring the subglacial geomorphology. Using mixtures of cornstarch and water as an analogue model, I simulate the environment the flows erupted into and test Mathews’s hypothesis.
