During the California Gold Rush, Drytown—two miles south of Plymouth—was a hotspot with a population of 10,000. As the first place gold was discovered in the area, it is the oldest community in Amador County. It took its name from Dry Creek, which runs dry in the summer. It once had stables, blacksmiths, butchers, schools, stagecoach service, several mercantile outlets—and 26 saloons. A post office opened in 1852. By 1857 the gold had diminished, so when a fire destroyed most of the town that year, its residents moved on to other mining communities. The construction of State Route 49 in 1920, which runs through Drytown, saved it from total extinction. Today the community has a population of less than 200, a general store, a post office, and about five antique shops. The town is a registered California Historical Landmark.
