Students in GEOS 414 are supervised 24/7 by faculty and safety standards must be met. Therefore, space in the UA field course is limited to 20 students each summer. Admission is therefore not guaranteed for UA students. All qualified students from the University of Arizona or other institutions are welcome to apply. Admission is competitive, based on GPA and the overall quality of the application. 

Applicants must provide a copy of their unofficial transcript, with overall GPA and major GPA. A letter of recommendation from a faculty advocate is also required. All of these materials will be sent directly to Dr. Peter DeCelles, decelles@arizona.edu(link sends e-mail).

GEOS 414 is a five-week, 6-credit, capstone field course that integrates and builds on classroom-based knowledge to develop new understanding of geological processes, with a focus on the 2.5 billion year geological record of western North America. Our overall objective is to train geoscientists to solve complex, four-dimensional scientific problems using multiple working hypotheses and critical thinking. We prepare students for graduate school and careers in geoscience disciplines. Our classroom consists of the North American Cordilleran orogenic belt (the Rocky Mountains, Colorado Plateau, Basin-and-Range, and Sierra Nevada) and its spectacular geological landscapes, including the Grand Canyon, Grand Staircase and Bears Ears National Monuments, Bryce Canyon and Circle Cliffs National Parks, the Book Cliffs, and various mountain ranges in Utah, Wyoming, Nevada and California. Our faculty are renowned experts on the geology of the western U.S. Unlike many field camps, ours is mobile and designed to provide an integrated understanding of orogenic systems, leveraging the unique natural laboratory of western U.S. geology in a focused, distraction-free environment to promote personal and professional growth. Great testimonials on the benefits of field camps can be found in this article.

This course or an equivalent course at another university is required for the Geology and Geophysics sub-plans within the UA Geosciences B.S. major. GEOS 414 or an equivalent course can fulfill the 6-unit Capstone Experience for the Earth, Oceans, & Climate sub-plan requirements, as well as the Gem Science sub-plan requirements.

Students enrolled in GEOS 414 will put into action principles and knowledge acquired in their on-campus courses in geology, geophysics, and related sciences. Students will study a broad range of rock types in various tectonic and geomorphological settings in order to learn the geological and tectonic history of the western U.S. The various exercises are designed to provide students with an understanding of the Cordillera as an integrated tectonic system. Students depart from Tucson in University vehicles, accompanied by professors and teaching assistants, and travel from campsite to campsite for the duration of the course. The curriculum changes every summer to maintain a spirit of exploration and discovery. Meals will be prepared by a professional cook.

In addition to students from the University of Arizona, qualified students from numerous other universities enroll in GEOS 414. Admission is competitive, the tuition and fees are affordable, and the student:instructor ratio is low. These factors, along with the high level of training and scenic beauty of the study areas, attract students from all parts of the United States.

Cost for Summer 2026 is currently TBD.

•  To develop intellectual independence and critical thinking skills
• To develop practical skills to document rocks, geomorphic features, and other common geological elements in the field
• How to operate as an independent field geologist in all types of geological environments, including how to plan, manage, and execute field studies in general
• The geological history of western North America over the last 2.5 Ga
• The tectonic, magmatic, metamorphic, and geomorphic processes that worked together to form the North American Cordilleran mountain system
• To develop wilderness skills and confidence in mountainous terrain
• How to create and interpret maps and cross-sections in all kinds of rocks and Earth materials, and to integrate surface and subsurface data

Although all of these and many more topics will be covered in detail in the course, it helps to come as well-prepared as possible.

•  Review basic rock types and rock-forming minerals
• Review the geological time scale
• Review major structural and geomorphological features
• Review sedimentary processes and major depositional environments
• Review metamorphic and magmatic processes (both intrusive and extrusive)
• Be ready to think in three dimensions and through geological time
• Be prepared for extended hiking in rough country

GEOS 414 is a challenging course and students must be prepared for variable weather conditions and hiking in rugged terrain. Students must also be properly attired and equipped to carry out this work safely. Backcountry campgrounds have limited facilities. Cell phone reception is also limited, and students should not expect to be in continuous contact by phone with family/friends. Days off are scheduled weekly to allow access to facilities in nearby towns. Watch some of the videos on this website to gain a better understanding of the landscapes and some of the activities involved in this unique course.

UA GEOS BS students who have significant health concerns, physical or other disabilities should apply for the GEOS 405 Accessible Earth or an equivalent field experience that better fits their needs. Alternatively, students may request a Disabilities Resource Center (DRC) accommodation for fulfilling their Capstone Field Experience requirement with a reasonable alternative to their specific needs. Students needing a DRC accommodation should submit the DRC Affiliation Form as soon as they become aware of the need for an accommodation as this process can take several weeks or more.

Safety is our primary concern. However, accidents do sometimes happen. Admitted students who injure themselves prior to attending the GEOS 414 camp should notify the GEOS Field Camp Director, Dr. Peter DeCelles (decelles@arizona.edu) to assess whether attending will pose safety concerns for themselves or other camp participants. Admits who need to withdraw from the GEOS 414 program should check the academic drop/withdrawal deadlines on the Registrar's Dates & Deadlines website. It is the responsibility of each camp participant to notify one of the camp instructors as soon as reasonably possible if they or another camp participant is injured or becomes sick. More details about field safety are provided at the outset of the course.

Many other universities offer 6-credit field camps that can be transferred to UA. These camps vary in the type of experience, when the experience is offered and for how long, the number of credits earned, cost, the application process, etc. UA GEOS BS students are urged to apply for a variety of field camps, as well as the UA GEOS 414 Geology Field Camp, to ensure they are able to complete their 6-unit minimum Capstone Field Experience requirement within a timely manner. UA GEOS BS students who are attempting to complete their Capstone Field Camp Experience are currently required to engage in in-person experiences. At this time, online Field Camp Experiences have not been approved for future semesters.

Information on other field camps can be found on the following websites. Contact your Major Advisor if you are unsure of what camps can fulfill your degree requirements.

• United States Geological Survey (USGS)
• Geology.com
• Alternative Field Camps for UA students 

Students are encouraged to contact the GEOS Field Camp Director Dr. Peter Decelles (decelles@arizona.edu)), to discuss GEOS 414 Geology Field Camp course content and rigor if they have any concerns about whether GEOS 414 is a good fit for their personal situation

Students are responsible for meeting all dates and deadlines that are posted on University websites, especially related to enrollment and financial dates and deadlines.

Students from other majors or institutions should schedule an appointment with their major advisor if they have any questions or concerns about fulfilling their specific degree requirements with our GEOS 414 Geology Field Camp course.
