    The Longest Cave System in the World

    The Longest Cave System in the World

    This is the first episode in a series of 3 on the world's longest cave system - Mammoth Cave in Kentucky. In this episode, Chris and Jesse talk a little about Mammoth and some of its impressive statistics. The focus however, is more about the necessary ingredients for cave development in general. We talk about the 4 general ingredients: suitable rock type, a solvent, hydraulic gradient, and time. We also go into some detail on what each of these really mean. We h...

    The Uniqueness of Iceland

    The Uniqueness of Iceland

    In this episode, Jesse and Chris talk about the geology of Iceland - although we keep it at a high level. We're going to come back to this - Iceland - later after Chris returns from his trip. Then, we'll get into some of detail that makes Iceland so unique. Here, we discuss how Iceland might be a prototype for the formation of continents and also talk a bit about the diversity of igneous rocks that make up the Island. The diversity of rocks speaks to the diversity of v...

    Tough Soil - The Geology of Hardpan

    Tough Soil - The Geology of Hardpan

    Hardpan! Where did this idea for an episode come from? Chris has been doing a ton of yard work lately and it’s not uncommon come across a layer when digging a hole that is next to impossible to penetrate. He has to bust out my pick axe to get through it. It's Called Hardpan.Really dense layer that often occurs below the topsoil. Problems:Roots can’t penetrate into the hardpan (Hayden Valley in YNP). Trees are easily blown over if they can even grow he...

    When Continents Became Stable

    When Continents Became Stable

    Today we really go into the weeds. Jesse and a colleague just published a paper in the journal Nature that proposes a new model for how continents became stable. Stable continents have all the granite at the surface, which contains all the heat producing elements like U and Th and K - elements that decay away. Today, we discuss that paper in detail, and along the way learn a bit about the early Earth, what we know and don't know! Here is a link to the paper, which is open access and can be do...

    Earth's Oldest Stuff

    Earth's Oldest Stuff

    Today, Chris and Jesse get into a discussion about Earth’s oldest material. Earth is 4.568 Billion years old. First of all, that’s amazing the geochronologists have refined this down to 3 decimal places. How do we know this? The oldest grains ever found are 4.38 billion years old. If that’s the case, then how do we know the Earth is significantly older than that? Join us as we answer that and many other important questions about Earth’s oldest stuff. ...

You led the charge.

I listened to this podcast in the spring of 2023. I am currently in my 2nd semester of school, with a duel major of environmental geoscience and environmental planning with a minor in hydrology. I give all credit to you guys, your podcast made me fall in love with learning about earth. You all make it so exciting and fun and I learn so much from it. Keep it up! Look forward to listening more. Always telling people they need to look you up and listen! Thanks guys so much!!

Great at the “so what”

This podcast is great and breaks down geology in an interesting way so that it is easily understandable. Chris and Jesse balance the conversation and explain why the geo science is important while providing the technicalities. Would like a little more girl power, but they do this with many of their guests.
