Overview

Chapters

• 00:00 - 00:30: Introduction to Wakulla Springs Wakulla Springs is a popular destination in Florida, known for its cool waters that provide a relief from the heat. Tourists enjoy the main beach, while locals prefer the less crowded opposite bank. Despite the presence of cold-blooded creatures, the springs have been a historic site of interest for many years. However, the exact timeline of human visitation remains unknown, prompting archaeologists, like National Geographic grantee Jim, to investigate.
• 00:30 - 01:00: Archaeologists Search for First Floridians Dunbar and his research team are on a quest to uncover signs of the first Floridians who lived over ten thousand years ago. During the ice age, Florida resembled the Serengeti, teeming with various animal populations. These animals would gather around oasis-like areas, which is likely where early human inhabitants might also have settled.
• 01:00 - 02:30: Discovering Prehistoric Tools and Dating Sand Layers This chapter explores the search and discovery of prehistoric tools and the process of dating sand layers. The narrative imagines a landscape abundant with water resources and large herbivores attracting predators, such as saber-tooth cats or humans. The aim of the crew is to find ancient tools once used by Ice Age hunters. The search involves digging in a traditional manner seeking to uncover Stone Age artifacts.
• 02:30 - 03:30: Investigating Mastodon Bones The chapter titled 'Investigating Mastodon Bones' explores the meticulous process of examining each bucket of materials. Experts carefully screen for the smallest clues, while geologists use the properties of sand to determine the age of discoveries. Quartz crystals in the sand are key, as they emit a radioactive signal reset by light exposure. By testing this signal, geologists like Jack Rink can establish when a sand layer was buried. The chapter highlights this investigation process, including how Jack takes a core sample to aid in dating and analysis.
• 03:30 - 04:30: Using Ground-Penetrating Radar In the chapter titled 'Using Ground-Penetrating Radar,' researchers study radiation levels in sand to determine the last time it was exposed to light. This process helps them date artifacts found during archaeological digs. Specifically, archaeologists have uncovered hundreds of small artifacts, primarily small flakes, which they are analyzing to connect with the dating of the sand.
• 04:30 - 05:30: Discovery of a 14,000-Year-Old Knife The chapter titled 'Discovery of a 14,000-Year-Old Knife' describes an exploration led by underwater archaeologist Andi Hemmings. The dive team is investigating fossilized Mastodon bones, and clues begin to surface about ancient dietary habits through the discovery of stone hunting tools nearby. The focus is on uncovering what prehistoric humans might have eaten, integrating elements of forensic science in the analysis.
• 05:30 - 06:00: Conclusion and Future Expectations In the chapter 'Conclusion and Future Expectations', the narrative unfolds around a significant archaeological discovery made underwater at a depth of 25 feet. The team of divers documents their findings meticulously, capturing details of deep grooves etched into a mastodon fossil. This discovery sparks speculation and excitement among the team, as these markings could possibly be attributed to the activities of an Ice Age hunter. The chapter encapsulates the awe and mystery surrounding ancient history and sets the stage for future explorations and discoveries.
