Analysis of Frozen lake

Beautiful is the frozen lake
Don't walk on it, it might break
Ducks are landing on the ice
Tumbling over like a dice
They are sliding on their buts
Someone whispers, do you have guts
To walk on the thin icy layer
Don't do it, not even with a prayer
It is glistering nicer than the stars
Breaking ice doesn't jars
It is ringing sweet like gentle music
Waves are covered, can't make you seasick
But this beauty bears a danger
Don't disregard the warning of the ranger
