Keystone Award

Starting a new tradition in 2019, the Arizona State Historic Preservation Office, Arizona Preservation Foundation, and host city of the Arizona Historic Preservation Conference have presented the Elisabeth Ruffner Keystone Award for Community Leadership. The award honors individuals whose commercial, political, philanthropic, artistic, planning, or advocacy efforts have contributed to their communities' quality of life, sense of place, and heritage appreciation.


“In construction, the keystone connects and stabilizes the whole, providing necessary support and strength. And our award recognizes community leaders whose motivation and passion have fostered the resources and connections necessary for preservation to thrive within their communities." ~ Kathryn Leonard, State Historic Preservation Officer


“The Keystone Award's namesake, Elisabeth Ruffner, was a tireless advocate for historic preservation who devoted her public life to enhancing her hometown of Prescott. She was a co-founder of the Arizona Preservation Foundation back in 1979. This award honors Arizonans who likewise have made their homes better places, enhanced civic identity, and become indispensable Keystones of their communities.” ~ Jim McPherson, Arizona Preservation Foundation Board President


2022 Honoree – Tina Clark, Yuma​

  • Tina wrote grants that secured more than $10 million in funds for the Yuma East Wetlands, Gateway Park, and West Wetlands

  • The Great Recession threatened the closure of both Yuma state parks by Arizona State Parks in 2009, and the community had to step up to save them. Coming from a diverse professional background of archaeology, museum curation, and interior design, Tina worked within the space of six short months to transform the museums at the Yuma Territorial Prison and Colorado River State Historic Parks into showpieces that could be sustainably operated.

  • In her “spare” time, Tina devoted herself to preserving many of Yuma’s historic treasures including rehabilitation of the National Register listed St. Paul's Episcopal Church at 637 2nd Avenue into a reception and catering venue. Operating until 2022, “Tina’s Cocina'' was known far and wide for its great food, music, and fellowship.

  • Tina provided important archaeology monitoring services for the Quechan Indian Tribe for many of their projects, as well as for other sites within the National Historic Landmark.

  • Tina developed and gave legendary walking “Ghost Tours” in downtown Yuma for residents and visitors alike. She brought Yuma’s history to life in a fun and entertaining way.

  • Tina’s work with the Arizona Historical Society to rehabilitate the Sanguinetti House into a museum destination not only reimagined a historically significant space that had grown tired, but also sparked a community-wide effort to bring the Sanguinetti gardens back to life and to develop a shared vision for the revitalization of the Molina Block.

Yuma artist Judy Phillips was commissioned to create the 2022 Keystone Award. Judy's fused glass design depicts the historic Ocean-to-Ocean Bridge and the iconic Yuma Territorial Prison guard tower. Watch this YouTube video of Tina's work in Yuma!
