Girls* On Rock (GOR) is a FREE pre-college program consisting of a backcountry expedition to explore the Rocky Mountains through scientific research, artistic expression, and technical rock climbing. The program is designed for diverse youth 16-18 years old identifying as girls* (cis or trans) or nonbinary or gender non-conforming youth from backgrounds that are historically underrepresented in the Geosciences (e.g., Black, Indigenous, and People of Color (BIPOC), low-income). The program provides 9 participants, who have lacked access to the outdoors, the opportunity to participate in a 12-day rock climbing and backcountry wilderness expedition, facilitated by 2-3 instructors and a certified mountain guide. While in the field, participants design and conduct their own research projects, gaining experience with the scientific process. The expedition culminates in a public presentation of their research, open to all researchers and the public, allowing for a festive celebration of the accomplishments. Girls* on Rock recruits volunteers every year to support many aspects of the program, from reviewing applications to hiking gear into the backcountry with the team. Please consider signing up to help this year's expedition!
