October 23 Hometown Geology: The Big Island of Hawai'i
I'm on fall break right now! (That's why the first minute sounds funky) While I'm off, enjoy an episode of Hometown Geology from our Patreon, on the house! If you like what you hear, check out Bedrock on Patreon for more- you can listen, vote, or even suggest your own topics!
This episode covers two main stories: how the Hawaiian Island chain formed, then a quick tour through seven(!) volcanoes on and around the Big Island. Enjoy!

October 08 57: New Horizons
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.

September 24 56: The Council of Time (Season 3 Premiere)
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.

August 27 Mail Time! Dylan answers your questions
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!

July 29 55: The Oldest Rock in the USA
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.

July 15 54: The End of an Era
We finally end our great Greenland adventure with one final question: how did all these diverse rocks become squeezed together, 3.6 billion years ago? The answer to that question can tell us a lot about how the early Earth worked. According to some folks, plate tectonics was very similar to today. To others, Earth was a very alien world indeed. Along the way, we'll visit trenches off the coast of Japan, and turn our hands into tectonic plates.

July 01 53: The Great Fossil Debate
At long last, we finish the cliffhanger from Episode 52!
Last time, I introduced one of the greatest debates in paleontology and geology. Are a few little triangles on the Greenland tundra Earth's oldest visible fossils, or just some funny-looking rocks? Today, we'll discuss both sides like a court case, laying out a decade of debate. This has been an episode Dylan has waited a long, long time to produce!

June 22 The Return of Bedrock and Hometown Geology
Good news: After six months, my girlfriend's hospital odyssey is wrapping up for now.
Bad news: My visiting professorship at GVSU has finally ended, and the job hunt continues.
For better and for worse, I have more time to return to the podcasts. Bedrock and Hometown Geology will alternate on Wednesdays. The Brisbane episode of Hometown Geology will air June 24 for Patreon subscribers, and Episode 53 of Bedrock will air July 1.
Thank you all for your patience once again, I'm excited to get behind the microphone again!

February 19 Life Update: Medical Hiatus
This brief update explains the long pause in episodes. A month ago, my girlfriend had a major, sudden hospital visit. The operation went smoothly, but there are many more hospital visits in the next few months. Episodes will return, but probably not until March. As always, thank you for your patience and well wishes!
