What kind of imagery is used in "Stopping By Woods on a Snowy Evening"?

Robert Frost’s “Stopping by Woods on a Snowy Evening” is
often taught in high school as an example of imagery and symbolism. As the above post
noted, Frost appeals to several senses with the images he creates by word choice (also
known as diction).

It is also important to realize that
Frost is using imagery to do more than appeal to the readers’ senses, he is also using
imagery to create a symbol that helps impart a deeper meaning to the
story.

The poem concludes with the following
lines:

The
woods are lovely, dark, and deep

But I have promises to
keep,

And miles to go before I
sleep,

And miles to go before I
sleep.

In this final stanza
Frost uses imagery to shift the poem’s focus from description to symbolism.  The image
of the woods as “lovely, dark, and deep” are considered by many to be a symbolic
reference to what death is like. It prepares the reader for the final two lines, “And
miles to go before I sleep,” which is emphasized by repetition, and refers to actual act
of dying. 

By using images to create his symbol, Frost has
made his poem memorable. The fact that the poem has been taught in school for decades
attests to this fact.
