After passing though the tree line , where temperatures are too low on average to sustain tree growth , the ground changed to alpine tundra . These low , hardy plants and flowers dodge the high winds just a few feet above and are insulated by snow cover in the winter . Elk and big horn sheep venture here as well , and we saw a good number of elk grazing below the road .
How do low , hardy plants and flowers dodge the high winds just a few feet above and are insulated by snow cover in the winter ?
