A great deal of scientific research is currently focused on documenting and understanding the causes and effects of global climate change. Mid-latitude glaciers, such as Grinnell Glacier in Glacier National Park, are some of the best and most easily observed indicators of climate change in the lower 48 states. Experts predict that Grinnell Glacier and all of the Park's remaining glaciers will disappear completely by 2030.

This day hike will take participants to Grinnell Glacier in the Upper Swiftcurrent Valley. Classroom discussion will include natural cycles in the sun's radiant energy, the greenhouse effect, anthropogenic factors causing global warming, and flora and fauna shifts being observed at higher latitudes in North America. Glacial geology and geomorphology are integral to understanding Glacier Park's geologic history. So participants in this hike will become proficient in glacial terminology and recognize the features of a glacially formed landscape. In addition, participants will learn about the billion year-old Precambrian bedrock geology that dominates all of Glacier Park and explains the striking red, green, tan, and white bands of the Park's rock formations that are beautifully exposed along the Grinnell Glacier Trail.
