Ice Krispies

We approached the Hubbard Glacier,
More than seventy miles long,
And we watched it calve and listened
To its snap-pop-crackle song.

As chunks of ice broke free and fell
(That's calving) we could hear
The glacier pop and crackle
Very loud and very clear.

Occasionally, underwater 
Pieces broke off, too
And they popped up to the surface 
In a burst of white and blue.

They're fondly called "ice krispies,"
Like the cereal whose goal 
Is to crackle, snap and pop
When milk is added to the bowl.

It's super cool (no pun intended)
Watching Nature's feats
So I'd rather watch ice krispies
Than consume Rice Krispie Treats!
