Location
Bedrock is the county seat of fictional Cobblestone County, and stated in the first season episode "The Tycoon" to be 200 feet below sea level; presumably, the nearby town of Red Rock was located in Cobblestone County as well. However, no further information was ever given for any of these locations, besides being set in a prehistoric version of the United States. Near Bedrock lies Granitetown, given in one episode as the one-time childhood hometown of Barney Rubble and Fred's boss, Mr. Slate.
Bedrock in one episode is shown as being a two day drive from Rock Vegas, and in another episode, several hours' drive from Indianrockolis, which suggests that Bedrock might be located in what is today the Midwestern United States.
Travel to Hollyrock, the prehistoric entertainment capital of the country, usually involves an "airplane" flight --- the "plane" in this case often shown as either a giant pterodactyl (with the passenger compartment being a hollowed-out log strapped to the pterodactyl's back) or a wooden plane with smaller pterodactyls on each wing as the "engines".
The third season episode "The Buffalo Convention" shows Fred and Barney going to a lodge convention in Frantic City.
The season two episode "The Rock Vegas Caper" shows the Flintstones and the Rubbles, while driving to Rock Vegas, passing the Grand Canyon; being in prehistoric times, however, the "canyon" is depicted as little more than a small stream. Fred, however, notes it "might be a big thing someday."
It has also been suggested that Bedrock is fairly close to the ocean, as the city has a yacht club, plus the Flintstones and Rubbles have taken several trips to the beach.
