In the science fiction novel Lucifer's Hammer, written by Larry Niven and Jerry Pournelle, fragments of a comet strike the Earth, causing massive tidal waves to destroy most of the planet's coastal cities.

The second half of this novel focuses on an enclave of civilization in the fictional "Silver Valley", located slightly east or northeast of Springville, and just north of the Middle Fork of the Tule River.
