Two American schooners, Hamilton and Scourge, sank in Lake Ontario during a storm in the War of 1812, with over 80 sailors lost. These wrecks are now among the best-preserved wooden shipwrecks, thanks to the cold, freshwater environment. Father-and-son divers, Mike and Warren Fletcher, joined a scientific expedition to explore the wrecks. The challenge was accessing the deep wrecks, as scuba diving was limited, requiring remotely operated vehicles (ROVs) to penetrate the schooners' interiors. To understand the crew's experience, the Fletchers used a shipwreck simulator to recreate the storm conditions. They aimed to learn why so many sailors were trapped and drowned, with hypotheses pointing to the storm's sudden intensity and structural issues on the ships.

This documentary film explores the marine mysteries of the Magdalen Islands, the Quebec archipelago in the Gulf of Saint Lawrence, North America's tempestuous inland saltwater sea. Over 700 sunken ships are documented by Leonard Clark and three generations of his family in the village of Old Harry

In this episode, Simcha looks into the discovery of a cave just outside of Israel that houses some very peculiar stone carvings. The cave is not far from where an ancient roman garrison was housed in the year 70AD and bares evidence of both Roman and Christian iconography carved into the ancient walls.
