For nearly fifty years, the quarries produced steadily, amounting to more than 4.5 billion dollars in sales.
1896 records indicate 1,000 men were employed among the quarries, carving 160,000 loads of stone in a single year with a market value of 3.75 million dollars.
In 1883 Green built a three-story hotel and opera house complex on his estate known as Columbia Hall.
With little more than $100 and a number of promissory notes based on the success of the art colony they leased 10 acres (40,000 m2) of land on the estate.
The parcel of leased land included the Green Mansion, the Ice House and Water Tower.
