Bergmann's Rule

A moose near Missoula, MT. Moose in Montana are some of the smallest moose in North America.

On a sunny June day, I was standing among a group of budding naturalists, sketching the bark of a cottonwood tree. Suddenly, I heard a series of quiet gasps and more than a few titters ripple through our small crowd. Someone had spotted a cow moose and her calf crossing the path just a few feet away from us. We all turned to watch them on their route to the Bitterroot River.
