Recording the location of Grinnell Glaciers Terminus via kayak

Recording data on the terminus of the glaciers found in Glacier National Park is a critical component of understanding the impacts of global climate change on the park. This scientist is using GPS units to record precise locations of the edges of Grinnell Glacier. Sometimes this requires being a bit creative in how you reach the edges of the ice.
