Ponderosa Ranch entrepreneur David Duffield in 2004. In September 2004 he closed the Ponderosa "indefinitely". Ponderosa Ranch The Ponderosa Ranch was a theme park based on the popular 1960s television western "Bonanza", which housed the affluent land, timber and livestock-rich Cartwright family. The amusement park operated in Incline Village, Nevada, near Lake Tahoe, from 1967 until 2004. Portions of the last five seasons of the TV series and three TV movies were also filmed at that location. The Ponderosa was the fictional setting for "Bonanza". According to the 9th episode ("Mr. Henry Comstock") in the first season, it was a thousand-square mile
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.
