Waves Wear Away What Waves Make

A lake is an island
In an ocean of stone.
Every island’s fragile.

One day the waves could turn
To ice, then stone. The lake
Could be gone. In a day

An island can vanish.
When their great ice dams broke,
Agassiz, Missoula,

Freshwater inland seas
Vanished overnight. Grief
Belongs to the oceans.

Stone belongs to the crust
And iron to the core.
Earth’s an iron island.
