New National Historic Landmarks
NHLs are some of the nation’s most historically important buildings, sites, structures, objects and districts, which communicate themes in history, archeology, architecture, engineering and cultural significance. NHL designation is the highest federal recognition of a property’s historical, architectural, or archeological significance, and a testament to the dedicated stewardship of many private and public property owners who seek this designation.

New National Natural Landmarks
The newly designated NNLs include Glenwood Caverns and Iron Mountain Hot Springs in Colorado, and John Boyd Thacher State Park in New York. These additions join 602 other locations that recognize and encourage the conservation of sites that contain outstanding biological and geological resources, bringing illustrative character, rarity, diversity and value to science and education.
Glenwood Caverns and Iron Mountain Hot Springs in Colorado, a privately owned site, features unique cave processes and ecosystems. In addition to beautiful cave formations that line the floors and ceilings of the caves, these unique ecosystems are habitat for a variety of species including eight native and fully cave-adapted animals.
John Boyd Thacher State Park – which is managed by the New York State Office of Parks, Recreation, and Historic Preservation – features the most complete and minimally disturbed record of Middle Paleozoic rock layering in the Appalachian Plateaus region, and perhaps across North America. The uniquely accessible fossil-rich deposits provide a visible geologic cross section spanning 63 million years that is foundational in the early study and understanding of North American geology and of widespread ancient mountain creation.
