CAMERON PARK was established by Robert L. "Larry" Cameron, also known as "Calgary Red". Before he turned to real estate development, Cameron was a successful bronc and trick rider in a wild west show, car salesman and dealer, and cattle breeder. After closing out his career as a Pontiac dealer in Sacramento, Cameron purchased 5,000 acres in the Sierra foothills for cattle ranching. Eventually the land was divided into parcels and individual lots. The first real estate development opened in 1963, about the same time as El Dorado Hills'. The Camerons moved to CAMERON PARK in 1974.

Cameron Park reflects a wide scope of interests, with ranch sized properties, medium and high density residential, shopping areas, a championship country club, recreational lake and the Airpark Estates. The Cameron Airpark Estates provides a unique opportunity for pilots to commute from home to destination without ever leaving the plane. Wide streets double as taxiways between homes and the airstrip.

SHINGLE SPRINGS was named for the cool spring that flowed near a shingle mill built in 1849. Mining in SHINGLE SPRINGS started in 1850. That same year two brothers (Harry and Edward Bartlett) built an inn which was called the SHINGLE SPRINGS House (later known as the Locust House). The SHINGLE SPRINGS Post Office was established on February 3, 1853.

The area was riddled with rich placer mines, yielding up to $200 per rocker per day. With the discovery of gold came people and the first general store in 1865. In 1865 the Placerville & Sacramento Valley Railroad was extended to SHINGLE SPRINGS, but in 1867 the railroad focus shifted to the transcontinental line going through Auburn and Truckee. As claims failed the miners moved on, but cattle ranchers and farmers saw the value in these hills and continued to support the area. In 1895, the name was changed to Shingle, and in 1955 it was changed back to SHINGLE SPRINGS.

RESCUE was named for a mining claim called the RESCUE Claim, because its owner (Andrew Hare) said it had rescued him from poverty. The town came into being on June 12, 1895, when the first Post Office opened. During the Gold Rush times, the RESCUE area was the site of several waystations (inns and stores). Extensive mining took place locally and thousands of people made this area their home.

The Old Coloma Road passed through RESCUE and was traveled by James W. Marshall from Coloma to Sutter's Fort as he reported his first discovery of gold in January 1848. This road was also used by the first stage line in California. In 1860-61, the Pleasant Grove House located on Green Valley Road (west of RESCUE) served as a remount station for the Central Overland Pony Express.
