Arnold is acensus-designated place (CDP) inCalaveras County,California, United States. The population was 3,288 at the 2020 census. Arnold is located onState Route 4.
Arnold is named after Bob and Bernice Arnold, who, in 1927 opened the Ebbetts Pass Inn. Prior to that, the community consisted of two large ranches where logging was the main industry. The inn served as a stop for people traveling along theEbbetts Pass route as well as lodging for those visiting nearbyCalaveras Big Trees State Park. In 1928, Camp Wolfeboro was established nearby as a Boy Scout camp and continues to be in operation today. The first post office was opened in 1934.[2] Bernice was its postmistress at one time.
In 2015 power lines sparked theButte Fire, which destroyed 549 homes in nearby communities. Arnold was saved when the weather changed, but the fire caused an increased focus on fire safety, although the community was still, in 2019, considered a "very high fire hazard severity zone" due to its location on a ridge outsideCalaveras Big Trees State Park, surrounded by dense forest of trees killed by drought and beetles.[3]
According to theUnited States Census Bureau, the CDP has a total area of 9.1 square miles (24 km2), of which, 9.1 square miles (24 km2) of it is land and 0.1 square miles (0.3 km2) of it (0.71%) is water.
Arnold is considered at high risk ofwildfire byCalFire due to its forested ridgetop location with powerful wind gusts up brushy canyons.[3]
