Bighorn sheep herd in and around Grand Teton NP could die out unless helped, biologists say
They’re rarely seen from highways, chairlifts or hiking trails. They eke out an existence at elevations far above tree line, spending three to four months of the year in temperatures as low as 40 below zero and winds strong enough to keep the snow away.
They eat whatever grass is dried and left over from fall or scrape lichen off of rocks. They hunker down in their thick fur coats and spend hours completely still.
