Which text in this excerpt from n. scott momaday's the way to rainy mountain uses a simile to create a vivid picture?
for my people, the kiowas, it is an old landmark, and they gave it the name rainy mountain. the hardest weather in the world is there. winter brings blizzards, hot tornadic winds arise in the spring, and in summer the prairie is an anvil's edge. the grass turns brittle and brown, and it cracks beneath your feet. there are green belts along the rivers and creeks, linear groves of hickory and pecan, willow and witch hazel. at a distance in july or august the steaming foliage seems almost to writhe in fire. great green and yellow grasshoppers are everywhere in the tall grass, popping up like corn to sting the flesh, and tortoises crawl about on the red earth, going nowhere in the plenty of time.
