W Diamond Ranch — a tribute to ranching and the natural landscape


"We have been long time cattle ranchers in the state of Arizona since 1965 and we appreciate  conservation easements protecting rural lands."

 -Claudette Haverfield, owner of Seven Spears Ranch.


A row of massive Fremont cottonwoods stands sentinel over what may be the crown jewel of conservation efforts in Central Arizona, a testament to the importance of preserving local ranches, scenic views and wildlife habitat in the Prescott area.

Located about 20 miles southwest of Prescott near the unincorporated town of Skull Valley, the W Diamond Ranch affords sweeping views of Kirkland Peak towering above rich bottom lands with lush riparian vegetation. Rolling hillsides dotted by artesian springs flourish with native grasses, mesquite, hackberry, desert willow, oak, manzanita and mountain mahogany.

The ranch is also home to abundant wildlife, including coyotes, javelina, deer, elk, bobcats, mountain lions, foxes, roadrunners, hawks and other birds of prey and waterfowl.

The ranch is adjoined by State Trust land and U.S. Bureau of Land Management lands, linking it to other undeveloped open lands, primarily used for grazing.

Skull Valley rancher Dave Jenner, began assembling smaller ranches in the 1950s to create the W Diamond containing a total of  4,296-acre deeded acres. Dave had the vision to place his ranch under the protection of an agricultural conservation easement with the Central Arizona Land Trust in 2007.

Jenner was motivated to protect the property due to the rapid growth he’d witnessed in the area over the decades as a resident, county commissioner and school board member. By placing his ranch under an agricultural conservation easement, he ensured preservation of this diverse property for generations to come. As part of his agreement with the Central Arizona Land Trust, small parcels were reserved as future home sites, as well as the educational, organic farm site for Prescott College.

In return for donating the easement to the Central Arizona Land Trust, Jenner received federal tax benefits specific to conservation easements, along with the peace of mind that his ranch, including its rich bottomlands and water resources, will forever remain intact.

In June 2015, the ranch sold to the Haverfield Family Trust. Vern Haverfield and Claudette (Haverfield) Johnson were delighted to buy the ranch after admiring it for some time. Today, Claudette continues running the ranch as a cattle operation, now called the Seven Spears Ranch. 

The landscape of the Seven Spears Ranch is unique and unparalleled. The ranch stands out as the keystone of CALT’s portfolio of protected properties not only because it’s the land trust’s largest conservation easement, but also because of its biodiversity, dedication and cultural importance in helping maintain the historic tradition of ranching in the Prescott area.

The Central Arizona Land Trust is an Arizona nonprofit corporation and is tax exempt under Section 501(c)(3) and a qualifying organization under Section 170(b)(1)(A)(vi) of the Internal Revenue Code for the acceptance of conservation easements.
