Strawberry Mountain looks down upon Prairie City, creating one of the most photogenic vistas on the Journey Through Time. After its founding in 1868, Prairie City had to be rebuilt three times following major fires. Much of its importance as a shipping point for Grant County was due to the Sumpter Valley Railroad lines, with its narrow-gauge tracks running from Baker City to Prairie City.

The Great Depression ended this connection, although the shortened Sumpter Valley Railroad continued to transport logs to sawmills in Baker City until 1947. The original train depot in Prairie City has been restored and is now the DeWitt Depot Park Museum.
