Dinosaur National Monument preserves a wide variety of natural resources, both from the past and present. The geological and paleontological resources here provide glimpses into environments millions of years ago in the form of fossilized plants and animals. Today, the diversity of life in Dinosaur's rugged environment is a reflection of climate and complex geography. The monument provides habitat for more than 1,000 native species of plants and animals. It includes more than 200,000 acres (809 sq. km.) of natural features and ecosystems in the canyons, mountains, rivers, and basins. Elevations range from under 4,750 feet (1,448 meters) near the Quarry to over 9,000 feet (2,743 meters) at the park's highest point: Zenobia Peak. Dinosaur National Monument also has one of the most complete geologic records in the National Parks System, with 24 exposed rock layers. These combine with elevation and topography to create the many habitats that the park's wildlife calls home.
