Bedrock: Earth's Earliest History

Show Notes

What's the next step after the oldest rock on Earth? Today, we'll move the story forward 200 million years and 1,000 miles. The time: 3.8 billion years ago... or maybe much older (March 3 on the Earth Calendar). The place: Nuvvuagittuq (noo-voo-ah-git-took), Quebec, Canada, in the lands of the Inuit. In this episode, we'll learn how this seaside outcrop was found and the ongoing debate about its' exact age. Depending on who you talk to, these are either the second-oldest rocks on Earth, or almost as old as the Earth itself.

Today, we visit the three major locations for Season 3. A three-ring circus of rocks, if you will. One area is a remote desert full of ancient fossils. One area is a forested mountainland with evidence for global catastrophes. One area is our most populated region yet, full of iron mines. Dylan has visited two of these three locations, and hints at a few personal field stories that will set Season 3 apart. Check out bonus episodes on Patreon! One-off donations on Paypal

Welcome to Season 3 of Bedrock! This season will cover the Paleoarchean Era, from 3.6 to 3.2 billion years ago, or March to April on the "Earth Calendar". Get ready for more fossils and strange new rocks! In this episode, we'll see why Season 3 begins and ends when it does: an extinction? an impact? or something more random? On the way, we'll visit geology's great "Council of Time", meet a bishop who was a founder of modern geology, and make a cake on the edge of the Grand Canyon. Want bonus content?

While we're on a break between seasons, and while I'm starting my new job, I figured this would be a nice palate cleanser. There's no script, just answers like I'd actually give in person. If YOU want your question to be on a future Mail Time (and listen to bonus episodes), join our Patreon here! Today, I talk about the day I fell in love with "fossil pond scum", some of my favorite field locations, and my favorite time period in Earth history. Enjoy!

Season 2 Finale! For 50 years, the title of "USA's Oldest Rock" was held on the prairies of western Minnesota. In 2025, that throne was usurped by a brand new study. Where is this "new" ancient location, what rocks are here, and how old are they? Stay tuned to find out! Dylan has an exciting announcement: he has a new visiting professor job at Gustavus Adolphus College in Minnesota! Thanks to everyone for their support.
