The story
An accidental discovery, 1894
In 1894, adventurer Billy O'Neil went searching for silver on Ice Mountain and found something far stranger — a shaft 10 feet wide and over 30 feet deep, filled with ice.

Edwin Swift Balch described it as a true glacière naturelle — the most impressive natural refrigerator known in the eastern United States.
