Analysis of Moonlit Mountains

I stand here looking at the setting sun
That's just about to drop from out of sight
Yet soon to recognize, when it is done,
The always rising of the moon at night.

To see it creep above the curving east
And feel refreshing chill of dusk and slow
The landscape underneath completely fleeced
With silver light that makes the shadows grow.

And it's a sight to see the aspen trees
Take on themselves, each leaf, the evening strange;
With flooding darkness all about their knees,
The mountains over Colorado change.

Far up above the spruce cross tundra grass
 See moonlight silhouetting Eagle Pass.
