"White Pines," Robert Morgan

Standing beneath huge pilings.
Up there where the sea broke, browsed along the sand
millions of years ago.
A faint surf breaks far overhead.

From The Strange Attractor: New and Selected Poems.

Morgan is best known for the novel Gap Creek, one of Oprah's book club selections, which is how I met him, but he was reasonably well known as a poet before he became famous for his fiction, as evidenced in this 1997 interview. Read his poems "Pi" and "Mountain Dulcimer."
