I stand upon this grandest rim
Try to imagine unthinkable time
Relent before too long such fruitless task
Instead I’ll contemplate this lazy little rhyme
Through the plateau
The Colorado pickaxe falls
Reveals sedimental sandstone rings
The eons marked on canyon walls
Rock bottom finds the hardest rock
Twelve hundred meters down below
There an ancient granite shield
No deeper can the river go
But wider still
The river’s reach
A force of will
The cliffs be breached
Upstream the river
Has not yet found
The basement rock
So burrows still into the ground
