Science Moab

Brian Davis, an associate professor at the University of Louisville School of Medicine, loves looking for small fossils. His research focuses on early mammals, particularly teeth, jaws, and skull parts. Brian’s most recent discovery is a mammal fossil quarry in Cisco, Utah, part of the Morrison Formation dating back to the Jurassic period. The site has yielded small animal fossils, including some potentially significant early mammals that correlate with a nearby site in Fruita, CO. We discuss the complexities of fossil excavation, preservation, and the analysis process as well as the importance of student education.

Across the Colorado Plateau, pinyon-juniper ecosystems are facing more and more stress due to increasing heat and aridity. Today we talk with Seth Munson, a plant and ecosystem ecologist with the U.S. Geological Survey Southwest Biological Science Center in Flagstaff, Arizona. Seth’s research focuses on how dryland ecosystems respond to drought, wildfire, invasive species, and land-use to assist land management decision-making. He is currently working with the National Park Service to assess the areas of dieback of pinyon-juniper woodlands in the SE Utah Parks. The research involves both ground surveys and satellite imagery to create maps detailing the intensity and recovery of dieback over time.

Randy Irmis, a paleontologist and curator at the Natural History Museum of Utah, discusses his research on the Chinle Formation, (Triassic, ~201 to 230 million years ago) located in southern Utah. The Chinle Formation is characterized by river and stream deposits in a semi-arid environment, and is rich in fossils including vertebrates, plants, and trace fossils. Despite the historical lack of paleontological work in Utah compared to neighboring states, recent discoveries in the Chinle have significantly increased knowledge of life in the Triassic. We talk about the process of collecting and preparing these fossils for study and exhibits at the museum and Randy emphasizes the importance of public lands and the legal and ethical procedures for fossil collection and preservation.

Tony Mancuso is the Sovereign Lands Program Manager for the Green and Colorado Rivers at Utah’s Department of Natural Resources (DNR). His management efforts focus on maintaining the health and navigability of waterways under state jurisdiction, including removing invasive species and restoring natural habitats. Tony talks about specific projects like the New Rapid and Gold Bar side channels aimed at enhancing fish habitats and wetland environments. He also emphasizes the importance of public education and engaging youth through programs like Science Moab. The discussion highlights the challenges, collaborative efforts, and long-term commitments required in resource conservation and management.

Ryan Barton emphasizes the importance of collaboration and negotiation in solving water issues and bringing resilient water systems to the Navajo Nation. As a hydrologist working for the Navajo Nation Department of Water Resources, Ryan has been involved in projects for over a decade including hydrographic surveys, lake capacity studies, and the San Juan River Basin Crop Inventory. Science Moab talks with Ryan about his most recent and ongoing efforts to successfully provide drinking water to the Westwater community west of Blanding, UT through extensive collaboration among various entities. Ryan’s path into hydrology has been influenced by family and childhood experiences of nature conservation.

This podcast concludes a 3-part series on Moab’s creek corridors. The series includes restoration processes on the creeks, stream water gauge science, and this episode, fire fuels mitigation along Mill and Pack creeks flowing from the west side of the La Sal Mountains. Fire risk is high in creek corridors and other overgrown areas. The dense corridors could spread fire quickly through Moab and Spanish Valley. We talked with Duncan Fuchise, the forest stewardship program manager with the Utah Division of Forestry, Fire and State Lands, as he hopped between work sites along the Mill Creek Corridor one morning in March 2025.

It is the mission of the U.S. Geological Survey to monitor water resources across the country. We talk with Chris Wilkowske, a hydrologist with the USGS at the Utah Water Science Center, about the science and methodology of measuring stream flow. We talk about how stream gauges operate and the process of validating and adjusting data, particularly after events like floods. Local examples from the Moab area and the Colorado River highlight the dual purposes of stream gauges for flood monitoring and groundwater assessments.

Charlie Carpenter, a Braided Science Conservationist with IndigenousLed, discusses their work focused on reintroducing buffalo to Indigenous lands. The process of buffalo reintroduction includes land suitability assessments, political hurdles, and funding challenges. The initiative aims to restore buffalo, a keystone species, to their native habitats, benefiting both Indigenous cultures and ecosystems. Charlie highlights the importance of braided science, which integrates traditional ecological knowledge with Western science. We also talk about other upcoming projects including medicinal gardens and intertribal beaver councils.

Dr. Karletta Chief, Director of the Indigenous Resilience Center at the University of Arizona, leads initiatives for Tribal water security and community-driven climate solutions. Dr. Chief, a Diné hydrologist and professor, shares how growing up in Black Mesa on the Navajo Nation has influenced her current work. She emphasizes the importance of utilizing traditional knowledge alongside western science, and ensuring Indigenous communities’ central role in decision-making. We learn about the powerful mission of the Indigenous Resilience Center, and Dr. Chief shares her hopes for empowering the next generation of Indigenous youth to lead and innovate in their communities.

This is a special episode of Science Moab. "Dear Ovis” is taken from a live radio show during a recent Radiothon at KZMU Moab. Host Jordan Lister and local scientist Robin Reibold answer hypothetical science questions from the fourth-grade class at HMK Elementary School in Moab. Robin, a biogeochemist with diverse expertise, addresses interesting scenarios such as what would happen if the Earth were split in half, the consequences if all toilets in Moab were flushed simultaneously, and the impacts on humans if we had no pores. It’s a fun show that blends scientific facts and insights with humor.

Not everyone looks at the night sky in the same way. Science Moab talks with Autumn Gillard, the Cultural Resource Manager for the Paiute Indian Tribe of Utah, who shares her passion for the night sky influenced by her grandmother's teachings. We discuss the importance of the night sky in Southern Paiute culture, including its influence on traditional stories, dances, agricultural methods, and ecological knowledge. The conversation touches on the cultural differences in interpreting celestial bodies among various tribes and Western astronomy and the significance of winter storytelling. Autumn emphasizes preserving and passing down this knowledge through storytelling, mentorship programs, and community outreach events, and advocates for recognizing the scientific contributions of Indigenous people.

This show is part of a series exploring Science Moab’s School to Science Program, connecting students with scientists in the field, the lab, and beyond. This program began in 2021 and to date has mentored over 57 local students. In this episode, we talk with mentor Sarah Karinen, botanist and lead technician for the Northern Colorado Plateau Network of the National Park Service, and Maya and Ari Jacobs, juniors at Grand County High School. Sarah has sponsored several day long job shadows with local students facilitated by Science Moab. Maya and Ari spent a day with Sarah in the field at one of the NPS pinyon juniper long term test plots in Island in the Sky. They helped measure trees, learned a lot of different plant names, and talked about ecology out in nature.

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 the restoration includes the removal of invasive species like Russian olive and tamarisk, which are replaced with native vegetation to mitigate fire hazards and improve ecological health. These projects also aim to manage flooding in Mill and Pack Creeks by stabilizing creek banks and facilitating better flood control.

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. Recent Ponderosa tree mortality raised concerns among land managers and Larissa Yocom, a fire ecologist at Utah State University, began exploring the potential causes of these deaths. These include drought, insect attacks, and increased competition due to fire suppression over the last 140 years. This research underscores the challenges of ecosystem management, particularly under changing climates, and highlights the unique importance of these rare old Ponderosa stands.

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 California, Noah Pleshet, assistant professor of anthropology at the university of New Brunswick, and Ben Bellorado, assistant curator at the Arizona State Museum about their methods and the importance of involving descendant communities in the interpretation and preservation of these sacred sites. We talk about the educational and preservation goals of the initiative, the involvement of indigenous students and community members, and the future potential for expanding this technology-driven approach to cultural heritage.

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 particular, we look at the interactions of rabbit brush and caterpillars.

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. We talk with Scott Hotaling, Assistant Professor in the Department of Watershed Sciences at Utah State University, who is studying the rare stonefly in order to gain understanding of how alpine streams are faring as glaciers recede under a warming and drying climate.

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 elevation areas with cinder fall in the range of 3-10 cm would have become more suitable for farming, due to the beneficial effects of the cinder mulch. We talk with Volcanologist Michael Ort, who, together with a team of scientists, has unraveled the timing of these events and the implications of volcanic activity for humans at the time.

This show is part of a series exploring Science Moab’s School to Science Program, connecting students with scientists in the field, the lab, and beyond. This program began in 2021 and to date has mentored over 57 local students. In this episode, we talk with mentor Mary Langworthy, Public Programs Manager at the Moab Museum, and Klayre Humphreys, junior at Grand County High School. Mary has sponsored several day long job shadows with local students facilitated by Science Moab. Klayre spent a day at the museum with Mary in the spring of 2024 and ended up delving into the world of shark teeth which ultimately helped Moab Museum staff update and enhance their exhibit.

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 University of Nevada, Las Vegas. Drew’s interests and research center on understanding how climate influences tree growth in our changing environment.
