Angels Camp is California's most famous Gold Rush town, thanks to writer and humorist Mark Twain, who made the town in Calavares County the setting for his 1865 short story, "The Celebrated Jumping Frog of Calaveras County." The supposed event among jumping frogs is commemorated with a Jumping Frog Jubilee each May at the county courthouse. Angels Camp, which locals sometimes call "Frog Town," has adopted the croaking, tailless amphibian as its symbol, and one finds all varieties of frogs on signs, store advertisements, and souvenirs.
