Six decades later more than 600 locations across the U.S. ranging in size from four acres to more than 900,000 are designated National Natural Landmarks (NNLs).

Key Points: 
  • Six decades later more than 600 locations across the U.S. ranging in size from four acres to more than 900,000 are designated National Natural Landmarks (NNLs).
  • In 2023 a handful of NNLs will celebrate their 50th anniversaries of the designation, including the Morrison Fossil Area NNL in Colorado.
  • Later expanded to the Morrison-Golden Fossil Areas NNL, a section of the original designation includes Dinosaur Ridge.
  • While NNLs are not units of the National Park System, designation provides the opportunity for landowners who share an allegiance to protecting America's natural treasures to partner with the National Park Service in collaboration for conservation.
