Western Pennsylvania is known for many interesting geologic features, including those of glacial origins. Let’s explore the unusual features of two of Pennsylvania’s beautiful parks. Though very close to each other, Moraine State Park and McConnell’s Mill offer related oddly contrasting geologic wonders.

Anyone who has done geologic work in the Keystone State might wonder how things got so complicated. Pennsylvania’s geologic history is long and complex. Join us to explore how that complexity came about.

We don’t normally think about the relationship between the core of the Earth and the ability of the planet to support life. But it turns out that complex life on Earth would be impossible without a spinning iron-rich core producing the magnetosphere that shields us from the deadly solar wind. Let’s take a look upward and downward and examine the center of the Earth as well as its far-flung outer boundary.

Glaciers have been one of the most significant forces that have sculpted Pennsylvania in the last 50,000 years. Without the Pleistocene glaciations, the world would look very different and be a very different place to live. Let’s explore what glaciers are, how they form and why they are so important.

The White Clay Creek Park and Preserve is found in a unique setting both historically and geologically. While most of Pennsylvania is underlain by sedimentary rocks, the White Clay is within the Piedmont just above the coastal plain, and area composed almost entirely of high-grade metamorphic rocks. Come and explore the unique geology of this area.

Costa Rica is known for its mountains, rainforests, biodiversity, and beaches, but none of that would exist without the unique geologic history of this country. This history captured the curiosity of author Russ Losco and he set out on an adventure to unlock it. Join us as we talk with Russ about his book and tour Costa Rica through the eyes of a geologist.

Geoheritage sites are features of geology, both large and small-scale that are fundamentally important in understanding and appreciating the Earth and her origins. Join us as we talk with Dr. Adolfo Quesada-Roman, an expert from the University of Costa Rica, about the geoheritage here in the USA and around the world.

Water is life. Water in and of itself is not that uncommon in the solar system or the universe. But liquid water on the surface of a planet is unusual and it is absolutely critical to our existence. Without water, the Earth would be a sterile ball of rock revolving endlessly around the Sun, and we would not even exist. What makes water so vital?

Bonus content is provided in this extended version of Soil: The very skin of our planet. Earth is the only planet known to support life. Why is that so? Alone of all the planets in the solar system, the Earth is coated in a layer of soil, the very skin of Mother Earth. Soil is a symbiotic collaboration between biology and geology.

When preparing for or performing field work, we often plan for physical safety considerations such as wearing the proper PPE or knowing the nearest medical center in case of emergency. But what about social conditions you may encounter while on a job site? Join Russ Losco and Tiffani Doerr in an interview with Josh Anadu where we discuss an important and most likely overlooked aspect of field safety.

Over the course of six days, we traveled 350 miles starting out along the south shore of the Monongahela River in Pittsburgh on the Great Allegheny Passage Trail. We peddled through broad synclines of Pennsylvanian stratigraphy and anticlines exposing Mississippian stratigraphy as we made our Approach to the Appalachian fold and thrust belt.
