Now here is a massive undertaking -
Sutro Tunnel Restoration
As Virginia City's Comstock Lode mines got deeper and deeper, heat and ground water were challenges. Adolf Sutro came up with the idea of a long tunnel to drain them.
Sutro also had the idea to bore through the Sierra Nevada Mountains to Lake Tahoe to supply water to San Francisco. I'm sure glad that never happened.
