As with almost all of the photos I took on this outing, this is an HDR photo. I think that HDR is one way to preserve detail in snow, which would normally be fairly non-descript in its pure white form.
The title? It's the first line of Frost's famous poem "Stopping By the Woods on a Snowy Evening":
Whose woods these are I think I know. His house is in the village, though; He will not see me stopping here To watch his woods fill up with snow.
My little horse must think it queer To stop without a farmhouse near Between the woods and frozen lake The darkest evening of the year.
He gives his harness bells a shake To ask if there is some mistake. The only other sound's the sweep Of easy wind and downy flake.
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.
