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 ?
Pick the best answer from the following options:
- None of the above choices .
 - They get moisture from snow and need no water .
 - They grow close to the ground to keep from being damaged in the wind , but because there are no trees , they get full sun .
 - They actually move in the wind and avoid it .
