Castle Rock Mineral Springs Bottling Works was founded in 1889 in Dunsmuir, California, United States. The company bottled natural spring water which was shipped all over the world.
George Washington Bailey operated a resort and a hotel across the river from the Castle Rock Mineral Springs. A footbridge provided convenient access for tourists from the hotel to the springs. People traveled from all over the nation to visit the resort and mineral springs, which were said to contain healing properties.
The company operated profitably until 1906, when the San Francisco earthquake ended its plans to further divide up and develop the area commercially. The company subsequently went bankrupt during the 1929 stock market crash.
In 1943 the State of California purchased 925 acres of the Castle Rock Springs property, which was the beginning of Castle Crags State Park.
