where was the big country filmed

The Big Country (1958) was filmed primarily in California, with key locations including Red Rock Canyon State Park in the Mojave Desert near Cantil, California, and various ranch and plains areas around Stockton and Farmington in Northern California. Specific notable sites are the 3,000-acre Drais Ranch in Stockton for ranch scenes, Rock Creek near Farmington for the "Big Muddy" ranch and water scenes, and the canyon scenes at Red Rock Canyon State Park for the Hannassey homestead and cliff settings. Some scenes also involved Copperopolis Road and other outdoor locations around California. Although the film is set in Texas, these California locations were used to capture the vast western vistas and landscape. There is a mention of Canyon de Chelly in Arizona, but filming was predominantly in California.
