r. Thaddeus Hildreth and his brother set up the camp known as Hildreth's Diggins in the lovely Sierra foothills. More than 150 tumultuous years later, Columbia is an amazing example of a true gold rush community frozen in time. But this is no ghost town either--the downtown area, with its plank sidewalks, ornate hotels, and saloons, is preserved as a California State Historic Park. The town today is a living, breathing, modern community at peace with both its past and its present. It's easy to imagine characters from the Old West swaggering through these streets, which served as the backdrop to Gary Cooper's Marshall Will Kane in High Noon. Of course, given Columbia's frequent historical reenactments, one doesn't have to think too hard to conjure such imagery.
