The twentieth episode of The Curse of Oak Island season 13, titled The Sands of Time, promises to be a turning point in the long-running quest to uncover the island’s elusive treasure

Scheduled to air on March 31, 2026, this episode appears to push the investigation into new and unexpected territory—one that could redefine everything the team thought they knew about Oak Island’s mysterious past.

For years, the efforts led by Rick Lagina and Marty Lagina have focused heavily on the Money Pit area, where countless attempts have been made to locate a supposed buried treasure. However, The Sands of Time hints at a significant shift in direction. Rather than continuing to concentrate solely on known hotspots, the team appears to be exploring areas previously overlooked or dismissed—locations where no one expected anything of value to be hidden.

The episode’s preview suggests that this change in approach could yield remarkable results. Early findings indicate that artifacts or structural anomalies discovered in these unexpected areas may carry historical significance far beyond simple treasure hunting. Instead of just searching for gold or valuable objects, the team may be uncovering clues that point to a larger story—one involving multiple groups, timelines, and possibly even lost technologies.

One of the most intriguing aspects of this episode is the implication that Oak Island’s secrets may not be confined to a single location like the Money Pit. Instead, the treasure—or whatever lies beneath the island—could be part of a complex network of buried structures and hidden pathways. If true, this would explain why previous generations of treasure hunters failed to find definitive answers. They may have been looking in the right place, but not in the right way.

The title The Sands of Time also carries symbolic weight. It suggests that time itself plays a crucial role in understanding the island’s mystery. Layers of sediment, shifting ground, and centuries of human interference have likely obscured key evidence. By examining these layers more carefully, the team might be able to reconstruct a timeline of events that reveals who was on the island, what they were doing, and why they went to such great lengths to hide their activities.

Another compelling element teased in the preview is the possibility of advanced engineering. Some of the structures being uncovered appear too deliberate and sophisticated to be accidental. This raises questions about the people who built them. Were they pirates, as some legends suggest? Or could they have been members of a more organized and technologically capable group, such as early explorers or secretive societies? The episode seems poised to explore these possibilities in greater depth.

Moreover, the emotional stakes for the team are higher than ever. After years of searching, investing, and enduring setbacks, discoveries of this magnitude bring renewed hope—but also pressure. Each new clue adds urgency to the mission, as the team realizes they may be closer than ever to solving one of history’s most enduring mysteries.

Ultimately, Episode 20 of The Curse of Oak Island season 13 could mark a pivotal moment in the series. By shifting focus to unexpected locations and uncovering evidence with broader historical implications, the team may finally be piecing together the true story of the island. Whether or not they find a literal treasure, the knowledge they uncover could prove to be even more valuable—offering a glimpse into a hidden chapter of history that has remained buried for centuries.

As anticipation builds, one thing is certain: The Sands of Time is not just another episode—it may be the key to unlocking the deeper secrets of Oak Island.
