Grinnell Glacier is a glacier located in the US state of Montana in the Lewis Range of the Rocky Mountains. It is located in the northern part of Glacier National Park, near the Continental Divide. The glacier is named after George Bird Grinnell, a conservationist, explorer, and naturalist who was instrumental in establishing the park.
