The History of Mariposa
Mariposa started as a mining camp called Agua Fría. This was around 1849. The first town was about 6 miles (10 km) west of where Mariposa is today. Before the miners arrived, Miwok people lived in this area.
After floods and fires in 1849-1850, the town moved to its current location. This new spot was better because of its terrain and the presence of Mariposa Creek, which had a lot of gold. The gold in Agua Fría creek ran out quickly. So, people moved to the new boomtown.
A large gold mine soon opened in Mariposa. It used a 40-foot waterwheel to crush gold ore. This mine provided many jobs. Mariposa quickly became a supply center for hundreds of other mining areas. In 1851, the "new" Mariposa became the county seat. By 1854, the grand courthouse was built, which is still in use today.
John C. Frémont had a special land grant that gave him ownership of much of the Mariposa mining area. However, it was hard for him to protect his property. This was because so many gold seekers came to the area.
During World War II, the U.S. Army built the Mariposa Auxiliary Field (1942–1945). This field was used to train pilots. After the war, it became the Mariposa-Yosemite Airport that we know today.
In 2017, a large wildfire called the "Detwiler Fire" caused everyone in Mariposa to leave their homes for a while.
