An associate professor of geology at Southern Utah University, Dr. Johnny MacLean enjoys taking students outdoors to study in the region’s diverse landscape. With backyard access to Utah’s Bryce Canyon and Zion National Parks, Dr. MacLean’s students learn about geology in a remarkable real-world setting. He teaches upper-division courses in structural and environmental geology, tectonics, and field geology.
At SUU, Dr. MacLean serves as chair of the university’s general education committee, director of the Bachelor of Interdisciplinary Studies Program, and is a provost faculty fellow. He has also served as academic coordinator for SUU’s Semester in the Parks initiative, an outdoor study program that takes students into the National Parks to live and learn.
After completing a bachelor’s degree in geology at Furman University, Dr. MacLean earned a master’s degree in earth science at Syracuse University, and a Ph.D. in geosciences at University of Montana. Before joining SUU in 2002, he worked in the oil and gas industry in Texas, and in the environmental consulting industry in Montana.

Recreation: New Southern Utah, Utah State programs prepare students for outdoor careers
The Salt Lake Tribune
The semester will also include weekend trips to Zion National Park, Arches National Park, Capitol Reef National Park, the Grand Canyon and Great Basin National Park, academic coordinator Johnny MacLean said.
He stressed the program isn't about "vacation and sightseeing," but is meant to give students with interest in a future in Utah's outdoor industry a chance to take advantage of the state's geography in an unprecedented way...
SUU students will have the opportunity to study in Bryce Canyon National Park this fall
USA Today Network online
SUU assistant geology professor Johnny MacLean, who will be teaching a course entitled "Geology of National Parks," said the program was designed with a greater intent than just meeting course requirements.
“We’re mostly hoping the students see how complex systems are and national parks provide this great venue to see that complexity,” MacLean said. “We’re hoping this immersive experience really allows for deep and integrative learning. I think it will be a wonderful opportunity for students to learn about problems and questions within the real world.”

S-STEM at SUU
National Science Foundation $580,000
Through this S-STEM project, Southern Utah University (SUU) is recruiting and sustaining a cohort of financially needy and academically talented students in the STEM disciplines.
The Mesoproterozoic–Neoproterozoic sedimentary succession of the eastern part of the Siberian Craton consists of several unconformity-bounded, kilometer-scale siliciclastic-carbonate cycles. The overlying Lower Cambrian rocks are often compositionally similar to the uppermost units of the Neoproterozoic succession.
Because of the nature and process of precipitation, tufa deposits offer the potential to serve as sedimentary signatures of hydrology, climate, ecology, and biodiversity in areas otherwise lacking such historic archives. This study investigated a previously undocumented tufa site located in northwestern Arizona. Field mapping, X-ray diffraction, and thin-section analyses revealed a wedge-shaped deposit ...
The Rubys Inn thrust fault in southern Utah has produced several styles of deformation in its footwall. This project describes four exceptionally well exposed examples of strain accommodation, including a mountain-scale, ductile footwall drag fold, cataclastic flexural slip between bedding surfaces of differing competencies, plastically deformed petrified wood within the zone of flexural slip, and ...
In summer 2014, Southern Utah University’s field camp visited five national parks and forests to study five different tectonic settings in five weeks. These included: thick-skinned contraction of the Laramide Orogeny at Capitol Reef National Park; normal faulting due to salt tectonics of the Paradox Formation at Arches National Park; thin skinned folding and thrusting of the Sevier Orogeny at Fish Lake ...
Past observations of Mars have led scientists to believe that tectonic kinematics stopped early in its planetary development. Recent exploration of Mars has led to new theories that support an active tectonic regime on the Tharsis rise. With the advancement of new satellite imagery and technologies such as Thermal Emission Imaging System, High Resolution Imaging Science Experiment satellite ...
