Step-by-step explanation:
The poet uses imagery to create a vivid picture of the snow drifts and the imprint of a person's footsteps beneath them. This imagery is also used to reflect the mood of the poem, which is somber and melancholic. Additionally, the poet uses alliteration, such as in "hills of white" and "heart too bold," to create a sense of rhythm and musicality to the poem. This not only adds interest but also helps to convey the emotions of the speaker.
