Episodes
In this episode of the Don't Panic Geocast podcast, we continue our exploration of the Ice Age National Scenic Trail, immersing ourselves in its stunning landscapes and geological wonders. From glacial features to ancient river valleys, each step along the trail reveals new marvels waiting to be discovered. In the "Fun Paper Friday" segment, we dive into the intriguing world of gas marbles, unraveling their peculiar properties and potential applications.

In this episode of the Don't Panic Geocast, we dive into the fascinating world of dolomite, a mineral that is commonly found in sedimentary rocks. They discuss the unique characteristics of dolomite and the different ways in which it is formed. We also highlight a fun paper on equine dietary preferences, which explores the food choices of horses in different environments. The paper reveals interesting insights into the feeding habits of horses and how they adapt to different conditions
