Gallatin River
Moose are commonly observed in the park's southwestern corner along the Bechler and Fall rivers, in the riparian zones around Yellowstone Lake, in the Soda Butte Creek, Pelican Creek, Lewis River, and Gallatin River drainages, and in the Willow Park area between Mammoth and Norris. Summer moose migrations from south and west of the park into Yellowstone have been confirmed by radio telemetry. Moose usually live to 20 years in the wild.
