In "Bonanza" what is the nearest town to the Ponderosa?

"Bonanza" is an NBC television western series that ran from 1959 to 1973. Lasting 14 seasons and 431 episodes, Bonanza is NBC's longest-running western, and ranks overall as the second-longest-running western series on U.S. network television (behind CBS's Gunsmoke), and within the top 10 longest-running, live-action American series. The show continues to air in syndication. The show is set around the 1860s and it centers on the wealthy Cartwright family, who live in the area of Virginia City, Nevada, bordering Lake Tahoe. The series stars Lorne Greene, Dan Blocker, Michael Landon, Pernell Roberts (who left after six seasons), and later David Canary and Mitch Vogel.

The family lived on a 600,000+ acre (937+ square-mile) ranch called the Ponderosa on the eastern shore of Lake Tahoe in Nevada. The vast size of the Cartwrights' land was quietly revised to "half a million acres" on Lorne Greene's 1964 song, "Saga of the Ponderosa." The ranch name refers to the Ponderosa Pine, common in the West. The nearest town to the Ponderosa was Virginia City, where the Cartwrights would go to converse with Sheriff Roy Coffee (played by veteran actor Ray Teal), or his deputy Clem Foster (Bing Russell).
