Can the simple beauty of an organism be enough to want to restore and preserve it? If so, Aspen would be at the top of that list. So much more than a beautiful tree, a stand or group of aspen trees is considered a singular organism with the main life force underground in the extensive root system. We talk with Paul Rogers, professor and Director of the Western Aspen Alliance, about the threats to Aspen today across the west and the Colorado Plateau. In the face of increasing drought and fire across the Colorado Plateau, this resilient tree finds itself most susceptible to the vast numbers of animals that forage on its young and nutritious shoots.

Ever wonder how those amazing dinosaur bones make it from being embedded in rock to a museum where they are flawlessly displayed within a complete skeleton? Natalie Toth knows. Natalie is the Chief Preparator at the Denver Museum of Nature & Science and her job begins with a chainsaw in the field and ends with a fully prepared fossil display. We talk about the chain of events that must occur for this to be completed and about the backbone of this process which is building a world class Earth Sciences collection for researchers around the world to use.

Cirsium scopulorum, or mountain thistle, was long thought to be the only species of thistle occurring in the alpine tundra. Molecular, morphological, and geographical evidence now support the recognition of many species of thistles in the alpine tundra of the southern Rocky Mountains. We talk with Jennifer Ackerfield, the head curator of natural history collections, and the associate director of biodiversity research at Denver Botanic Gardens about her quest to delineate the many varieties of thistles across the alpine of the intermountain west, including a unique species right here in the La Sal Mountains of SE Utah.

Increased visitation and recreation in the desert inevitably leads to more human-generated noise. We talk with Joel Berger, University Chair in Wildlife Conservation at Colorado State University, about how this noise may or may not be affecting the iconic desert bighorn sheep. More specifically, we discuss how the noise may lead to increased prenatal stress on the females. The female bighorn typically give birth in the late Spring, which is when recreation in the SW desert is at its peak.

Given the increasing temperatures and aridity, the fate of pinyon-juniper woodlands on the Colorado Plateau is uncertain. We talk with Rebecca Finger-Higgens, Ecologist with the US Geological Survey, about the recovery of the pinyon-juniper woodlands in the La Sal Mountains following the Pack Creek Fire of 2021. Rebecca tackles the question of whether pre-fire forest thinning programs and post-fire seeding and erosion control expedite pinyon-juniper forest recovery.

Here in SE Utah, we are living in a geologically young, rapidly eroding landscape and we have the Colorado River to thank for sculpting such a beautiful and dynamic area. We talk with Joel Pederson, professor and Department Head of Geomorphology at Utah State University about his continuing research on incision rates of the Colorado River across the Colorado Plateau. We talk about some new advancements in age dating and why the area around Moab is currently the fastest eroding reach of the River.

High alpine talus slopes are home to a myriad of creatures, namely mountain goats and American pikas, both specialists in alpine habitats. We talk with Mallory Sandoval Lambert, whose curiosity about the interactions between these two mammalian herbivores led her to study their behaviors in the LaSal Mountains. Understanding these interactions will have important implications for the conservation of each species. This data will be particularly useful for both pika conservation and agencies tasked with managing the land that introduced mountain goat herds inhabit.

Around the world, civilizations have literally been built on rock and the specific rock type of an area has definite influences on that society. Science Moab talks with wildlife and science documentary writer, Gautier Dubois, whose recent work, Top of the Rocks, will be featured at this year’s Moab Festival of Science. Each episode of this 5-part series looks at a different rock (basalt, granite, sandstone, limestone, and clay) and how that rock influences our landscapes and environments. The Sandstone episode was filmed partially on the Colorado Plateau and features Moab scientist, Tim Graham.

On October 14, 2023, an annular solar eclipse will cross North, Central, and South America. Parts of SE Utah will be in the direct path of the eclipse. We talk with Cris White, Eclipse Coordinator for the Earth to Sky Interagency Partnership, about the uniqueness of eclipses and the many scientific activities that will be happening in conjunction with this year’s eclipse.

Sedimentologists are geologists that study rocks on the earth’s surface today in order to interpret ancient depositional environments. By studying deposits of river gravels, Andre Potochnik has been able to determine major changes in the drainages on the southern part of the Colorado Plateau. We talk with Andre about his work in Arizona on the Apache Reservation and how he has come up with the timing of significant drainage reversals for rivers in that area and how this impacts the interpretations of the Colorado River and the Grand Canyon.
