Friends of Sabino Canyon (FOSC) provides resources that conserve, protect, and enhance the Sabino Canyon Recreation Area located in the Santa Catalina Mountains within the Coronado National Forest north of Tucson, Arizona.

In 2009, FOSC commissioned Donor Recognition Art to design a donor wall system that would grow with the organization. Nina Borgia-Aberle designed ceramic tile donor wall panels set within metal frames, allowing for easy expansion as more donors contribute. A magnetic system facilitates the addition of new tiles. To date, 12 panels have been completed, providing space for hundreds of donors to honor their friends and loved ones.
