After attaining her bachelors degree, Becky worked as a wildlife technician on a bear nutritional study in Yellowstone National Park, a trophic cascade study in Waterton Lakes Park, and a bison management study in Montana. She then began teaching wildlife science programs to high school students in the Yellowstone area, which grew into a love of teaching and place-based outdoor education. Becky returned to the southwest and worked for a conservation corps building trail and working on invasive species projects. Becky does her best to balance indoor and outdoor work and to include the use of both her brain and her body. This balance has led her to work as an outdoor educator with Outward Bound, a Wilderness Ranger in the southern Rockies, and in the classroom with the High Mountain Institute and the Alzar School. Having lived in an arid environment for over 15 years, she is inspired by and passionate about water and its use. From the Colorado River to the tops of the San Francisco Peaks, to the Santa Fe Mountains, to the Rio Grande, Becky has adventured, studied, and worked within watersheds of the southwest. She spent time at the United World College in New Mexico with her hands in the dirt at the school farm and her intellect advancing the school’s sustainability goals.

Flow365 Outreach Intern

My name is Nicandro Guereque (He/Him) and I’m a freshman at the University of Arizona currently pursuing a Major in Music Composition and a Minor in Film. I’m originally from Colorado but moved to Tucson in 2009. I’m an Intern helping with the Hydro-Local Soundscape concert project and outreach for the Flow365 watershed monitoring program. In High School, I attended a sustainability conference in Berlin where we looked at the city’s urban farms and co-ops to see the ways that Berlin was environmentally friendly. This trip made me realize the role I can play in my community regarding sustainability issues like water conservation. I believe that Music and Art are important for reaching out to people and bringing awareness to climate change and the loss of our natural resources. My goal with this internship is to learn more about the history of Tucson’s rivers and watersheds and have an active role in helping my community.
