Today, Jesse and Chris discuss the distinction between sinkholes and karst topography.  There is a surprisingly large portion of the U.S. that has potential to be affected by karst.  It is also extremely important as a source of drinking water.  We also discuss the distinction between the technical definition of karst and what is called pseudokarst.  Below is a link to the article and diagram we allude to in the show.  We hope you enjoy.

In this episode, we tackle a listener question regarding planning a geology trip for students.  Both Chris and Jesse have quite a bit of experience in planning and executing field excursions for students.  We believe that seeing geology in the field is one of the most powerful learning opportunities for students of all levels.  In our discussion, we talk about the difficulties in convincing the higher-ups that this is actually a good idea.  We also get into some of the struggles in finding excellent teacher resources.  In the end, we get a little philosophical on the importance of getting comfortable with not having all of the answers.  We think that sometimes it's important for students to know that instructors don't know it all and together we can perhaps think about things different and come to new conclusions.  We hope you enjoy.  We now have a live Mobile App for iOS and Android.

The Rocks You Need to Know

Join us as we have the honor of interviewing Dr. John Douglas.  Jesse and Chris have been following his research on how the Grand Canyon was actually formed for some time.  We have recently finished our audio-visual book on the Grand Canyon (Link above) and we have a chapter dedicated to the actual cutting of the Canyon.  The answer to this question has been elusive, but there are a few leading theories.  John has been leading the way on the Spillover Theory as a mechanism for carving the young Canyon.  It's a great geologic discussion and we hope you enjoy.

Cutting the Grand Canyon - Dr. John Douglass

The idea for this episode came from the comment section of a social media post.  It has it's roots in one of the biggest misconceptions in Geology and also Geochronology.  The comment was about radio-carbon dating and how it's been "proven" to be unreliable.  In this episode, Jesse and Chris have a discussion about the "toolbox" for geochronoligists and we also spend a lot of time talking about Uranium to Lead decay.  We hope you enjoy.

Uranium and the Start of the Earth? - How Geochronology Works

In charge of the Nations Rock Collection.  That's a pretty sweet job description.  Join us as we have the honor of interviewing Dr. Mike Ackerson.  In this episode, we certainly get into some detail about igneous petrology.  Mike and Jesse are good friends and have spent some time discussing things that introductory geology classes take for granted.  For instance, there are some questions on the formation of granite.  This might seem ridiculous because this topic is covered in any intro level geology class, but there are some problems.

We also talk philosophically about geoscience education and scientific research.  In all, this discussion spans too many areas to summarize here.  We hope you enjoy!   We now have a live Mobile App for iOS and Android.
