Once a tall tower Mile Rocks is but a cylindrical turret with a helipad on its roof. Built in 1905, the original 3-tiered lighthouse sits on two rocks in the Golden Gate Straits opposite Lands End on the San Francisco shore.

50,000 ships
20,000 whales
On any given day, approximately 50,000 commercial maritime vessels navigate the world’s seas and waterways providing food and supplies to global communities.
Every year, cargo, cruise, and fishing vessels kill an estimated 20,000 whales. These ship strikes are a result of the overlap between whale feeding grounds and maritime shipping lanes, and an increase in vessels on the ocean.

Launched in 1818, the three-masted sailing vessel, that the Candace, was buried in mud and sand 168 years at Spear and Folsom Streets. Hugo sees the Candace - cut in two pieces and currently stored on Pier 50 - could be part of a rebirth of the Central Waterfront -
not unlike Fort Bragg and the blue whale
Adapting
Florida’s powerful Calusa natives, whose civilization thrived in the region for over 2,000 years, faced constant sea level fluctuations and storms. Evidence of their fishing and building adaptations can teach us about dealing with coastal change.
Hugo becomes intrigued by the history of Blind Key when he 'discovers' the Calusa watercourt buried in the mangroves.
The fictional barrier island of Blind Key is only a few miles south of Cayo Costa where the historical Hurricane Ian made its Florida landfall in September of 2022
