The Arizona Stone, one of two commemorative stones located within the Washington Monument associated with the state, has an overall dimension of two feet by four feet ten inches. The unique stone is carved from three rounds of petrified wood and resin adorned with gold leaf letters that spell “ARIZONA.” Sources indicate that the petrified wood was originally collected from the Chalcedony Forest in Holbrook, AZ, near present day Petrified Forest National Park. While the sculptor of the stone remains unknown, the research of National Park Service historian Judy Jacobs indicates that after the materials were acquired, the stone was sculpted in Los Angles, CA. After the initial installation of the stone, gold leaf was reapplied to the object during a relettering in 1939 as a joint effort between the National Park Service and the Arizona Society of Washington. Despite the completion of the Washington Monument in 1884, the stone is associated with the efforts of the Washington National Monument Society to expand representation within the monument of western states that started in 1911. The stone was installed in the 320 level of the monument, its current location, in 1924. According to the surviving historical record, the carving of the stone was sponsored by the Arizona Chapter of the Daughters of the American Revolution (DAR), an organization whose membership is based upon ancestorial participation in the American Revolution, which concluded 130 years before Arizona became a state.
