The Prophecy of Rocks

The rocks below you cry aloud …

The solid ground you stand on floats.
Foundations of your cities shift.
Beneath the crust the mantle stirs,

a seething churn of mineral stew
tracing circuits, trench to core
and back again to seafloor ridge

extruding mass from ocean vents,
paving plates with new basalt.
You ride on granite arks

above a superheated sea of ore.
As Earth rocks quarter billion year beats
continents glide around the globe

on an endless crustal contra dance.
Laurentia, Baltica, Siberia, Australia
diverge, divide, converge, collide

and cluster together again and again.
Nuna, Rodinia, Gondwana, Pangaea –
supercontinents always split.

Oceans are puddles that open before us.
We’ll bridge the Pacific inch by inch,
lurching west through quakes and jolts

that topple your ruins, shred the remains,
and bury the bones of your species’
descent beneath a supercontinent –

Amasia looms a beat ahead.
Earth rocks quarter billion year beats.
Foundations shift beneath your feet.

… and mock your brief dominion.
