The Treasure of Pleasant Valley is a 1955 historical novel by the American writer Frank Yerby.

[2] Yerby had already produced several bestsellers set in nineteenth century America including The Foxes of Harrow, A Woman Called Fancy and Benton's Row.

During the 1840s Bruce Harkness, a young southerner, heads west to join the California Gold Rush.

He enjoys a series of adventures and winds up in San Francisco after encountering the beautiful Juana.

He ultimately makes a success as a farmer rather than a gold prospector.
