The natural landscape and the weather both play a large part in setting the atmosphere and depicting the actions and mindsets of the characters in My Ántonia. Because the characters we meet are farmers, they are dependent on the natural world for their livelihood and therefore greatly affected by its changes. A harsh winter, for example, leads (perhaps indirectly, but still), to suicidal despair. The vast Nebraskan landscape is tied up with the novel's themes of youth and coming-of-age. (See "Symbolism, Imagery, Allegory" for more on this.) The relationship between man and the natural world is both humbling and awe-inspiring for the characters, which respect and admire the beauty of the prairie landscape.
