A group of 18th century, English explorers, searching for a Northwest Passage, are trapped in the ice off Cape Barrow. All die of scurvy, trichinosis, starvation, or madness. Late in the 20th century, an unemployed history teacher in the Puget Sound region of Washington State locates the journals of the ship's naturalist and its doctor, and begins editing them in the hope that the resulting book will help him find a job. There is a runaway nuclear reactor "accident." When, in the far distant future, the Pacific Northwest has cooled down enough to be reentered, the 18th century journals and the teacher's edition of them are rediscovered. These new papers are eagerly fallen upon by a scholar who beings to re-edit the 20th century edition. Ultimately, the three centuries converge in language-each with its own grammar, punctuation and spelling-a chorus of distinct voices."
