Once by the Pacific by Robert Frost

 The shattered water made a misty din.
 Great waves looked over others coming in,
 And thought of doing something to the shore
 That water never did to land before.
 The clouds were low and hairy in the skies,
 Like locks blown forward in the gleam of eyes.
 You could not tell, and yet it looked as if
 The shore was lucky in being backed by cliff,
 The cliff in being backed by continent;
 It looked as if a night of dark intent
 Was coming, and not only a night, an age.
 Someone had better be prepared for rage.
 There would be more than ocean-water broken
 Before God's last 'Put out the Light' was spoken.
