Teaching Alaskan geology on top of a glacier to high school students. The photo dramatically depicts melted glacier water with silt and other impurities that create diverse flow patterns. This photo was taken on July 30, 2019, in Palmer, Alaska, in the Matanuska Glacier. I designed and taught a class on scientific method in the context of geology reserach and explained the geology and glaciology components we saw in the field. The trip was part of a leadership fieldwork from Brown University that focused on training 31 high schoolers from all over the world about environmental issues.
