This bustling camp was once the home of Calamity Jane. Named after the castle-like rocks at Castle Mountain near White Sulphur Springs, there was little mining until about 1884. Castle then grew to be one of the richest mining camps in the state, supporting a $5000 school house, eighty homes, a jail, fourteen saloons and seven brothels. By the early 1890's it was almost deserted and by 1936 has just two residents. It is in central Montana between White Sulphur Springs and Martinsdale, north off Highway 294.
