Empty bottles left alongside a year-round spring located on the trail between Drytown and Mokelumne Hill gave rise to the site’s first name, Bottilleas, most likely an American corruption of the Spanish word for bottle, Botella. That name didn’t last long; however, as by 1849 the small settlement was known as Jacksons Creek, or more simply, Jackson. The camp was probably named in honor of Andrew Jackson, although some claim it was so-called for Colonel Alden Appolas Moore Jackson who may have mined here briefly in 1849, before moving on to the Tuolumne River where he established the mining camp of Jacksonville.
