Bonanza various times) Guy Williams, David Canary, Mitch Vogel, and Tim Matheson. The show is known for presenting pressing moral dilemmas. The title "Bonanza" is a term used by miners in regard to a large vein or deposit of silver ore, from Spanish "bonanza" (prosperity) and commonly refers to the 1859 revelation of the Comstock Lode of rich silver ore mines under the town of Virginia City, not far from the fictional Ponderosa Ranch that the Cartwright family operated. The show's theme song, also titled "Bonanza", became a hit song. Only instrumental renditions, absent Ray Evans' lyrics, were used during the
Ponderosa Ranch with a scale replica of the Cartwright ranch house and barn similar to the ones seen on television. A replica of Virginia City was later added. The original plan was to open the set to tourists once filming had wrapped. However, shuttling cast and crew up to Incline Village on a weekly basis became cost-prohibitive. Thus, only 15 episodes of "Bonanza" were shot there. A majority of ranch-specific scenes were shot on a sound stage at Paramount Studios in Hollywood. Outdoor scenes were filmed on location at nearby Big Bear Lake, Red Rock Canyon, Mojave, or eastern Kern County, California.
