Thank you Cathy and Matt for the excellent questions! Cathy sent us a question associated with This Article and Matt asked about Michigan geology (perhaps not knowing the long-winded answer he was in for!).
We received a TON of excellent questions from you all so we will have a Part 2 coming out soon - stay tuned to hear answers to your questions!

Devils Tower National Monument is a must see on any road trip in South Dakota! In fact, you can think of Chris Bolhuis while you are listening, as he is currently teaching 26 lucky high school students at Devils Tower at the moment!
The geology of this amazing spectacle has it all - beautiful sedimentary rocks, unique volcanic rocks, and great columnar joints that make the Tower look utterly striking.
Devils Tower is a unique rock called a phonolite, and it represents some part of an ancient volcano's plumbing system - a 40 million year old volcano!

Badlands National Park is a spectacular place to visit! If you are traveling to the Rocky Mountains, it is a great stop to get started.
Fossils are everywhere in the Badlands National Park, and the rocks have really amazing colorations to them.
However, badlands are a geologic feature! There are a few specific things required to form badlands and we discuss those key traits, as well as some of the basic principles of badlands generally.

After Listening back on this episode (both the short and the full interview), my wife and I had a conversation. I asked her what she thought. Her reply was that she was full of hope after listening. Join us as we have an incredible conversation with Ashley Grosh. She is Vice President of the Breakthrough Energy Fellows program which is designed to find and fund innovators working to bring climate technology solutions to the market. She worked at Wells Fargo for 15 years where she managed a $100 million impact program and was largely involved as a thought leader in the company's overall ESG (Environmental, Social, and Governance) and sustainable finance strategies and commitments.
Ashely is a former athlete and avid sports fan. She played Division 1 soccer for University of Colorado. She now coaches soccer for Colorado Elevation FC - academy soccer program.
Team sports, and the lessons one can learn, have always been a huge part of her life. In the Short episode, Ashley talks about the parallels between team sports and professional teams. She also wanted to sneak in some geology to the conversation by talking about a new way to mine from the seafloor. Here is the link that was alluded to in the episode: https://impossiblemining.com/

Carbon Dating: The Method and Misconceptions Jun 02, 2022

People often wonder, why can't we date diamonds? Today, we answer that!
Here, we talk through the basics of Carbon Dating, also called RadioCarbon Dating! Radiocarbon is an awesome technique that also has some really common misconceptions about it. We go through the basics of this amazing method, with great analogies as usual, and we cover all those misconceptions!
Carbon dating is a great tool for dating things that were once alive. However, the half-life of Carbon-14 is 5,730 years. This means that after something has been dead for over 50,000 years, there is virtually no Carbon-14 left to date. This is why Carbon dating can't be used on dinosaurs (or diamonds) - no Carbon-14 remains.
Also, Carbon dating is not an appropriate tool for dating most rocks for two reasons. First, most rocks don't have abundant Carbon-14 when they formed. Second, most rocks are very, very old. Fortunately, there are many other appropriate tools that scientists can use to date rocks. Jesse is definitely the expert in the room in this discussion. His research involves different dating methods that he's been using for years. We hope you enjoy the discussion.

Super_Volcanoes: Dr. Robin George Andrews May 19, 2022

Join us this week for our interview of Dr. Robin George Andrews. Robin George Andrews is a freelance science journalist based in London. His work has appeared in National Geographic, The New York Times, The Atlantic, Scientific American, Gizmodo, Atlas Obscura and elsewhere. He trained as a volcanologist, earning a doctorate in the subject, but then realized that telling people stories of spectacular eruptions and off-world scientific shenanigans brought him more joy than academia ever could. His upcoming book — Super Volcanoes: What They Reveal about Earth and the Worlds Beyond is out now - go buy a copy!
I must admit, it took Jesse and I a while to realize that the book is called Super Volcanoes - two words. In other words, all volcanoes are super. Most volcanologists strongly dislike the term Supervolcanoes - one word, that is typically used to describe Yellowstone National Park.
Robin has a huge personality which made for a very fun interview. We talked about Hawaii, Yellowstone, deep ocean volcanoes, Tonga, and Marie Tharp to name just a few. Tune in to get all the details. You won't be disappointed.
