The town of Moab exists because of the freshwater creeks that come off the La Sal Mountains into the alluvial fan the town was built on. We talk with Kara Dohrenwend about the science and efforts behind revitalizing creek corridors in Moab, including the history, current challenges, and strategic restoration plans for Moab's creeks. A key part of t…

Ray Mesa, near the La Sal mountains on the Colorado-Utah border is notable for its old-growth Ponderosa pines (estimated to be several hundred years old) that are growing in cool drainages amongst pinyon-juniper woodlands.

The Bears Ears Digital Cultural Heritage Initiative is a group of anthropologists, archaeologists, and indigenous communities collaborating to create virtual reality experiences and photogrammetric models of significant sites in the Bears Ears National Monument. We talk with Eric Heller, professor of anthropology at the University of Southern Calif…

Plants and insects are the key members of food webs because they are not only abundant and diverse, but they also provide food for many other animals higher up the food chain. We talk with Moria Robinson, Assistant Professor of Biology at Utah State University, about variations in these food webs as climate in the western U.S. dries and warms. In p…

Utah is home to over 800 rock glaciers. These masses of ice covered with rock debris are key to perennial streams and alpine biodiversity, but they are poorly understood.

Sunset Crater, the most recent cinder cone in the San Francisco Volcanic Field, is estimated to have erupted between A.D. 1085 and 1090. In areas where the resulting lava flows were greater than 30cm thick, people may have been forced to migrate, leaving behind long-established homesteads and agricultural fields. On the positive side, lower elevati…

As photosynthesis happens, trees take in carbon from the atmosphere and store it in the form of sugars or carbohydrates. These sugars can be stored for many years in trees as a sort of “memory” and used to support their growth and metabolism during times of stress, like a drought. We talk with Drew Peltier, ecophysiologist and professor at the Univ…

From the perspective of an archaeologist, the physical body of an ancient person is a gift because a body is a time capsule of the past. They lived in that space and that time, and their bodies are manifestations of what was there. We talk with archaeologist Erin Baxter, teacher and Curator of Anthropology at Denver Museum of Nature and Science, ab…

The Little Colorado River (LCR) is a culturally and spiritually significant drainage for many people in the southwest. The LCR also provides sediment load to the main stem of the Colorado River for the production of sandbars downstream AND it is an important spawning ground for and home to the largest population of Humpback Chub. We talk with Phoeb…

(Native American Tribes Upholding Restoration & Education), seeks to empower the next generation of science and conservation leaders on the Colorado Plat…

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…

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 ta…

We talk with Andre about his work in Arizona on the Apac…

Drylands encompass over 40% of terrestrial ecosystems and face significant degradation from a warming/drying climate and overuse. To combat this degradation, some restoration efforts have focused on the use of biological soil crusts (biocrusts): complex communities of cyanobacteria, algae, lichens, bryophytes, and other organisms living in associat…

Rivers have a magic way of healing, transforming and inspiring. From the calmest riffle to barnstorming haystacks, rivers always have rapids. This is how the river transfers energy. Monte Tillinghast grew up on rivers and has spent most of his adult years rowing the Grand Canyon of the Colorado. He knows a thing or two about rapids and has a gracio…

Aside from the inherent beauty of a pinon-juniper ecosystem, the health of such woodlands are tied to broader climate swings. This is the awareness that the project Sentinels hopes to bring to light. The brainchild of Todd Anderson, Bruce Crownover, and Gary Machlis, the Sentinels project uses art+science to showcase the pinon-juniper adaptation to…

While modern day river systems are highly engineered to efficiently move water, this is not necessarily a “healthy” condition.
