What They Left Behind

Is the meaning too cryptic, too obvious, or just right? This is a rough draft for contest.

Thin ice so white it hurt to see,

Atop a world of water black,

My footprints hope, in trailing dents,

To be laid flat by falling snow.

The silence pressed upon my back,

But shall I talk with none to hear?

In silent, barren, wasteland, that

Is all I have, my sanity.

And if I dropped the ice cube, I

Still keep within my ungloved hand,

It will not melt, that single piece

That lies forsaken, all alone.

I cannot bear the thought that it

Will stay unmelted in the snow,

And stay there for eternity,

And never die, amidst the cold.

My life, a walk in endless snow,

In silent, barren, drudgery,

Eternal night, in ocean deep,

Alone amid the freezing snow.
