History
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 the Ebbetts Pass route as well as lodging for those visiting nearby Calaveras 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. Bernice was its postmistress at one time. In 2015 power lines sparked the Butte 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 outside Calaveras Big Trees State Park, surrounded by dense forest of trees killed by drought and beetles.
