Frost's use of comparing girls drying their hair to nature is his greatest use of imagery. "Like girls on hands and knees that throw their hair before them over their heads to dry in the Sun." This excerpt has Frost comparing the image of the sun in girls hair to sunlight hitting the leaves of a tree.
“Soon the sun's warmth makes them shed crystal shells Shattering and avalanching on the snow-crust—Such heaps of broken glass to sweep away You'd think the inner dome of heaven had fallen.” Here, the author is defining the magnificence of the birch tree and the power that the winter weather has over it. The image of the bent-over birch trees shows how the constitution of the trees has been bent and changed by the force of winter.
