Robert Frost was an American poet known for depicting New England life through language in his works. Some of his notable poems are "Fire and Ice," "Mending Wall," "Birches," and "Nothing Gold Can Stay." He won the Pulitzer Prize for Poetry and congressional gold medal. The poem "Dust of Snow" describes how the author's mood was lifted when a crow shook snow from a hemlock tree branch above him, with the falling snow giving his heart "a change of mood" and saving part of a day he had regretted.
