Underwater robotics expert reveals 'shipwreck city' hiding beneath major urban lake

An underwater robotics specialist is revealing a "shipwreck city" hiding beneath a lake in a major West Coast hub — and much of it remains a mystery.

Remotely operated vehicle (ROV) specialist Phil Parisi is working to verify and document nearly 100 "targets" in Lake Union, a central lake in Seattle, Washington.

The urban lake has served as a working waterway for over a century, supporting shipbuilding and vessel traffic in the Emerald City.
