Valley Woman Triumphs After 45 Years: Sunnyslope Rock Garden Earns Historic Status

PHOENIX — The Sunnyslope Rock Garden in Phoenix has garnered historic status, safeguarding it from potential threats and ensuring its place in the community. Owner Marion Blake, who initiated the petition process 45 years ago, expressed relief at this accomplishment following years of dedication.

On January 5, 2024, Julia Taggart, president of the Sunnyslope Historical Society, visited the garden to support Blake’s efforts. As visitors entered, they signed a guest book alongside the petition aimed at the Phoenix City Council. Taggart described the numerous paperwork submissions Blake organized to advocate for the garden’s preservation over the years.

Originating in the 1950s, the rock garden was created by Grover Cleveland Thompson, who drew inspiration from an Oregon garden. He encouraged local children to contribute rocks to the site, fostering a strong sense of community. After meeting Thompson’s great-granddaughter-in-law in 1978, Blake purchased the property, committing herself to obtaining historic status for what is now the only protected rock garden in Arizona.

Community support for the garden’s preservation grew as Blake’s efforts became widely known. Residents expressed concerns when a sign indicating her intention to seek historic status was posted, but they quickly rallied behind the initiative. Taggart noted that many community members submitted letters in support of the garden.

At 83 years old and without access to modern technology, Blake faced challenges during the petition process. Taggart recounted touching moments when they met, recalling Blake’s emotional relief at finally receiving assistance. Together, they attended nearly every city meeting, culminating in a unanimous vote by the Phoenix City Council on December 4 to grant historic status.

Vice Mayor Debra Stark remarked on the significance of the garden, reinforcing its role as a cherished local landmark. For Taggart, the approval is not just a victory for preservation; it validates Blake’s long and challenging journey. “You always wonder… does my work matter?” she said. “It really did validate all the 45 years of trying for her.” The garden, celebrating 70 years of history, plans to commemorate this achievement, along with Thompson’s birthday, on January 1, 2025.
