In spring 2011, the SCPN-NAU School of Communication collaboration began with a multimedia studies course focused on documenting park resources and resource projects. The class was taught by NAU professors Laura Camden and Peter Friederici.

Each National Park Service (NPS) employee has a unique story. We can't tell them all, but sometimes there's a personal account—like that of Sallie Pierce Brewer Van Valkenburg Harris—that speaks to common experiences. Although her NPS connections ran from 1933 to 1971, many of her joys, challenges, and frustrations can still be recognized in the NPS today. Sallie's story resonates regardless of era, gender, or position. How will it speak to you?

When the climate changes enough, the vegetation communities growing in any given place will also change. Under an expanded bimodal climate zone, some plant communities in western national parks are more likely to change than others. National Park Service ecologists and partners investigated the future conditions that may force some of this change. Having this information can help park managers decide whether to resist, direct, or accept the change.

In the Verde Valley of Arizona, Montezuma Castle National Monument protects an impressive cliff dwelling, Montezuma Castle, and a large sinkhole. Montezuma Well, that were important to early peoples as they gradually transitioned from highly mobile societies to more sedentary ways of life.

Most women with disabilities hired by the National Park Service (NPS) in the 1970s and early 1980s had temporary jobs. Some built long-term careers with the bureau. Starting before the Americans with Disabilities Act of 1990, these women experienced the opportunities and changes the law brought. It was their hard work and dedication to the NPS mission, however, that continued to change attitudes and educate coworkers and visitors alike.

Across the US, changes in water availability are altering which plants grow where. These changes are evident at a broad scale. But not all areas experience the same climate in the same way, even within the boundaries of a single national park. A new dataset gives park managers a valuable tool for understanding why vegetation has changed and how it might change in the future under different climate-change scenarios.

Climate is one of many ecological indicators monitored by the National Park Service (NPS) Division of Inventory & Monitoring (I&M). Climate data help scientists to understand ecosystem processes and help to explain many of the patterns and trends observed in other natural-resource monitoring. In NPS units of the American Southwest, three I&M networks monitor climate using the scientific protocol described here.

At Montezuma Castle National Monument, the presence of prehistoric structures reflects the importance of reliable water sources. Sonoran Desert Network scientists monitor climate and groundwater at the park each year. Understanding changes in these closely linked resources helps the park make informed management decisions for both natural and cultural resources. This report summarizes the climate and groundwater data from Water Year 2024.
