Q: Passage: The Beverly Hillbillies is an American sitcom (situation comedy) television series originally broadcast on CBS from 1962 to 1971. The show had an ensemble cast featuring Buddy Ebsen, Irene Ryan, Donna Douglas, and Max Baer Jr. as the Clampetts, a poor backwoods family (from Ozarks of Arkansas or eastern Appalachian Mountains region) who move to posh Beverly Hills, California, after striking oil on their land. The show was produced by Filmways and was created by writer Paul Henning. It was followed by two other Henning-inspired "country cousin" series on CBS: Petticoat Junction, and its spin-off Green Acres, which reversed the rags-to-riches, country-to-city model of The Beverly Hillbillies.

Question: Based on this passage, where did the beverly hillbillies live before they moved to california? Let's give stream of consciousness first:
To answer the above question, the relevant sentence is: The show had an ensemble cast featuring Buddy Ebsen, Irene Ryan, Donna Douglas, and Max Baer Jr. as the Clampetts, a poor backwoods family (from Ozarks of Arkansas or eastern Appalachian Mountains region) who move to posh Beverly Hills, California, after striking oil on their land. Therefore, the final answer is Ozarks of Arkansas or eastern Appalachian Mountains region.
