On October 26, 2018, President Trump signed Proclamation 2018-24027, establishing Camp Nelson National Monument across approximately 6,271 acres of federal land in Kentucky. The proclamation invoked the Antiquities Act, the statutory authority presidents have used for over a century to designate national monuments on public lands. The designation protects a Civil War-era site where formerly enslaved people found refuge and subsequently served as soldiers and laborers, transforming it from undesignated federal property into a formally protected monument subject to preservation requirements and public access mandates.

The direct beneficiaries of this designation include historians, educators, descendants of those who sought refuge at Camp Nelson, and the general public, who gain guaranteed access to a site documenting a critical moment in American racial and military history. The monument's establishment prevents commercial development on the designated acreage and mandates that federal management prioritize historical preservation and educational access. Local communities around the site gained a cultural and educational resource, while the National Park Service acquired stewardship responsibilities for maintaining the property.

This action stands as a notable counterpoint to the Trump administration's broader environmental record documented in the archive. While the Camp Nelson designation represented a preservation measure, subsequent Trump administration policies systematically dismantled environmental protections across multiple sectors. The rescission of ethylene oxide pollution rules, the opening of Minnesota wilderness to mining, the payments to abandon offshore wind projects, and the invocation of the Defense Production Act for fossil fuel acceleration all reflect a dominant trajectory toward resource extraction and deregulation. The Camp Nelson monument represents an outlier within this pattern rather than indicative of environmental stewardship priorities.

The Camp Nelson designation remains active and has not faced successful legal challenge, distinguishing it from contested actions in other domains. However, its isolated nature within the administration's environmental record illustrates the tension between preserving specific historical sites and the broader rollback of protections affecting air quality, water resources, and renewable energy development.
