"The annual rite of spring in Glacier National Park is when the mountain goats drop down from their lofty perches to the goat lick on the Middle Fork of the Flathead River. They come down to the river not only to eat vegetation, which is slowly, but surely, greening up, but to eat (or lick) mineral soils," writes Chris Peterson/Glacier Geographic, Muse You Can Use.
