Fall is one of the best times of year for wildlife viewing in Yellowstone National Park. September dates were chosen to maximize chances of seeing the park’s famous megafauna at their best: elk are bugling, bears are preparing for winter by stocking up on food, wolves are hunting in Lamar and Hayden Valleys, and herds of bison roam Yellowstone’s grasslands. Add resident birds and fall migration to the mix and you have the makings of a wildlife wonderland.
These photos were taken during a recent Reefs to Rockies group trip to Yellowstone in September 2013.
