One of the great engineering feats in Nevada County hydraulic mining history was the drilling of the 7,874 foot drain tunnel, nearly 200 feet below you.

This project was engineered by Hamilton Smith.

Eight vertical shafts of up to 200 feet in depth intersected in the long drain tunnel.

The project was started in April 1872 and took 30 months to complete.
