The fictional Cartwright family lived on the Ponderosa Ranch at Lake Tahoe, and parts of Bonanza were filmed on its shores. The famous opening scene of Bonanza was filmed on location at North Lake Tahoe near Incline Village, and Lake Tahoe was among the outdoor locations used to film the weekly episodes.
The show is known for presenting moral dilemmas. The title Bonanza is a term used by miners in regard to a large vein or deposit of ore, and commonly refers to the 1859 revelation of the Comstock Lode discovery, not far from the fictional Ponderosa Ranch that the Cartwright family operated. The show's theme song itself called Bonanza, became a hit song in its own right.
