Located on the north bank of the Calaveras River, Jenny Lind was a placer mining town as early as 1849. Most of the placer mining was done along the hillsides above the river; later the river was mined with dredgers. In 1864 the population was said to be 400, half of them Chinese. Being on the main road from Stockton, it was also an important freighting center for the area.
