[1] In 2009, the Tonto National Forest made it its goal to develop and manage the cemetery as an interpretive site while preserving its historic context and integrity as an archaeological resource.

The role of Mattie Earp was played by actress Dana Wheeler-Nicholson in the 1993 American Western film Tombstone.

General George Stoneman established a military post by the base of the mountain close to Pinal City to protect the residents and the workers of the Silver King Mine from the attacks of the Apaches.

The historic cemetery is now within the jurisdiction of the Tonto National Forest in Pinal County since it is located in on lands administered by that agency.

[8] Among the improvements made in 2009, to the cemetery, after it became known that Wyatt Earp's second “wife,” was interred there, was the addition of a fence and signage with the added phrase "Historical".
