Natural shifts in light and dark are critical to all forms of life. We talk with naturalist and dark skies advocate Cris White about what darkness means to ecosystems and people. We also talk about the different ways that dark skies are being threatened and what is being done to protect them.

Changes are happening in plant communities in deserts of the Colorado Plateau and around the world. We speak with Dr. Steve Archer from the University of Arizona about the shifts in ecosystems primarily made up of grasses to those of woody plants and shrubs. The effects of this shift are wide reaching and have large effects for desert systems that we know.

Natural springs have long been centers of biodiversity and cultural significance. We speak with David Sabata who recently completed his masters degree from Northern Arizona University where he studied springs within the Grand Staircase Escalante Monument. We talk about his studies and how springs can be used to understand human settlement across the landscape.

We speak with Allison Stegner who is a post-doctoral researcher at Stanford University. She studies small mammals as a way to understand present and past environments. Here, we talk with Allison about her work and how studying small mammal abundance and distribution on the landscape can give us a better understanding of environmental change through time.

We speak with author/journalist Jonathan Thompson about mining history in SW Colorado and its impacts on rivers. His book “River of Lost Souls: the Science, Politics, and Greed Behind the Gold King Mine Disaster” explores the infamous Gold King Mine spill that released large amounts of acid mine waste into the Animas and San Juan Rivers. Here, Jonathan talks about the history of mining in the San Juan Mountains and its positive and negative effects on communities and ecosystems. We discuss how the Gold King mine spill is only a small part of a larger picture of the extractive industry in the Four Corners.

This show explores the social and ecological impacts of climbing in the Indian Creek Area, Utah. We talk with Zeke Baker and Steve Fick. Zeke is a PhD candidate in sociolology at UC Davis while Steve is a post-doctoral research ecologist with University of the Colorado Boulder and the USGS here in Moab. The two have teamed up to study rock climbing in the Indian Creek area and the social, ecological, and political interactions of climbers with this fragile landscape.

The understanding of snow...the various ways it falls from the sky and how it is transformed on the ground is critical to being safe in the backcountry. We talk with Mark Staples who is the director of the Forest Service Utah Avalanche Center. Mark graduated from the Montana State University Snow Science Program and here in Utah he and his team predict snow conditions for avalanche reports. Here with Mark we discuss the different forms snow can take when falling from the sky and the various ways that snow transforms once it is on the ground. This information is critical for understanding the snow stability and avalanche danger both in the La Sals and elsewhere around Utah and the West.

The world that existed when dinosaurs roamed the Moab area was vastly different than the world today . We talk with Dr. John Foster, a paleontologist and the former director of the Museum of Moab, whose work involves excavating the oldest known dinosaur Sauropod skeleton right here in the Moab area. Here we discuss a geologic layer known as the Morrison Formation and we explore the Jurassic Period…the landscape, plants and animals that existed 150 million years ago when the Morrison was being deposited.

Drought is impacting the plants that are growing around Moab and the Colorado Plateau. Here we talk to Alix Pfennigwerth, a former biologist with the US Geological Survey in Moab. We talk about different types of droughts that are expected to impact the plant communities we see on the Colorado Plateau. We explore how experiments provide insight into plant response to future drought due to climate change and what that might mean for the ecosystems and how we manage them into the future.

Deserts are characterized by having limited amounts of water. The plants that live in these dry climates are there because the soil holds onto just enough water for plants to survive. But climate change has the potential to change the amount of soil water available to plants. Here, Dr. John Bradford explains how soil moisture influences plant communities in the Southwest and how management actions & climate change can interact to alter water available to plants.
