Zero Mountain consists of a series of limestone caverns located at Johnson (Washington County) that have been developed into a refrigeration/freezer space of approximately thirty million cubic feet. The caverns, known as “the cave,” are owned by Zero Mountain, Inc., a $50 million operation founded in 1955 employing about 300 workers. The caverns are shown here in this 1929 photograph long before their development as a storage facility.
