Highway 40, Dinosaur, CO 81610 Purpose. Significance. Significance statements express why Dinosaur National Monument resources and values are important enough to merit national park unit designation. Statements of significance describe why an area is important within a global, national, regional, and systemwide context. These statements are linked to the purpose of the park unit, and are supported by data, research, and consensus. Significance statements describe the distinctive nature of the park and inform management decisions, focusing efforts on preserving and protecting the most important resources and values of the park unit. • The world famous Carnegie Quarry provides a remarkable window onto the Late Jurassic world of dinosaurs. There the National Park Service pioneered the in situ (in place) preservation of fossils, with 1,500 dinosaur bones available for viewing, touching, and study. This approach has served as a model for many other fossil sites around the world. • Dinosaur National Monument displays the most complete geological record of any national park unit. The 23 rock formations and their fossils reveal vast environmental and DINOSAUR NATIONAL MONUMENT biological changes over 1.1 billion years of Earth history, protects, studies, and provides access spanning the Pre-Cambrian to Cenozoic eras.

The Yampa’s natural snowmelt-driven flow provides a unique whitewater rafting experience and important habitat for native and endangered Colorado River Basin fish. Fundamental Resources and Values. • The confluence of the Yampa and Green Rivers within Dinosaur National Monument provides outstanding opportunities to observe and study a wild river (Yampa), a flow-regulated river (Green above confluence), and a hybrid river (Green below the confluence) within the context of the Colorado River Basin. Comparing the three river reaches informs management for long-term river ecosystem health and function in the face of climate change and human population growth. • The proposal to dam the Green River below Echo Park in the 1950s galvanized the nation’s fledgling conservation organizations into a potent political power that defended the national park idea.

The essence of Dinosaur National Monument involves the conservation Over 10,000 years of human heritage is also of a biologically diverse landscape of desert, mountains, and two river represented, including resources such as canyons, with an abundance of ancient fossils and past environments petroglyphs, pictographs, a variety of artifacts preserved in rock. This exemplary collection of resources is reflected by related to the prehistoric Fremont culture, and the two distinct moments in its history: the initial establishment of an 80-acre ongoing importance of these lands to Shoshone monument in 1915 to protect the “extraordinary deposit of Dinosaurian and Ute cultures. The monument also has a diverse and other gigantic reptilian remains,” and the 200,000-acre expansion in collection of histories and artifacts from European 1938 to protect the surrounding scenic canyons of the Yampa and Green and early American settlement and exploration, Rivers for many miles upstream and downstream of their confluence. including Spanish exploration, homesteading, ranching, and John Wesley Powell’s history of The geologic and paleontological resources in the monument showcase traversing the monument’s rivers. a great diversity of geologic landforms, 23 exposed geologic strata that developed over 1.1 billion years, and the associated plant and animal life, Dinosaur National Monument also provides most notably a world-renowned fossil record. Carnegie Fossil Quarry, a wealth of experiential opportunities for the marquee site at the monument, includes over 1,500 paleontological visitors that range from active recreation in wild resources and has shared fossils with museums around the world. The backcountry or on wild rivers, to hands-on monument also protects an exceptional living biological diversity that stems educational experiences at the many scientific from its location at the transition zone of multiple physiographic provinces, exhibits or cultural sites. Given its remote location, including the Wyoming Basin, Great Basin, central Rocky Mountains, and it also offers extensive visitor opportunities for Colorado Plateau. This location, combined with local topography that solitude, discovery, and appreciation of unspoiled spans high desert areas to riparian river valleys, provides a unique blend landscapes, skies, and waterways. of natural conditions that support over 1,000 plant and animal species. 10N BROWNS PARK To Rock Springs, Wyoming NATIONAL WILDLIFE REFUGE Ve rm ill ion C 8530ft 10mi re 2600m e 16km k 318 Gates of Lodore 34 5360ft 1634m Crouse Po Canyon t 318 Road C r e E e k R O Upper Disaster Falls UTAH D Lower Disaster Falls O 15mi L To Maybell, COLORADO 23km Colorado IN 18mi F S 29km D I A M O A N D O B A I B Harp Falls N O d G U N Zenobia Peak a L E o C O T A I N P H Z 9005ft R U N L A M O T E Y D A U 2745m Hole N N W O A M I Hells Half Mile es L C RED FLEET STATE PARK Jon I A D Triplet Falls D (Dinosaur Trackway) y D Jones Hole a 8380ft O w Fish Hatchery y U 2554m B G ic E n M L e l c y O A S k s S l U a e t i N n a i C e r r T U e r - e T A e k C g IN r e o l G o g s H n e M i m s n O a K l e o F C U n J N o O J n R r T e ive 5mi R A Jones Hole e T r 7510ft I N 9km A L CAN G O 2289m O LPO YON Warm Springs R B HI Rapids W M A E S Harpers Corner 7625ft T T S A STEINAKER 2324m Echo Park (summer only) R McKee Spring ISLAND V STATE PARK A Petroglyphs PARK Ruple Ranch 5079ft T 2mi Echo Park 1548m IO 3km N Park 7mi d Road Overlook Islan 12km able when pass we 12mi (Im t) 5mi DINOSAUR NATIONAL MONUMENT 19km Rainbow Park ek V e 8km A 44 6mi (no water) r L C L 10km E Island Park Iron Springs Bench N Y O Big Joe Overlook Overlook Y 191 8mi N K Rapids RUPLE l A YAMPA BENCH R N o C N TA I Moonshine o 13km A M O U POINT P Ya 4mi S P L I T P D m 4866ft Rapids N E pa 7km A L 1483m Schoolboy Ech Pa S ST o rk d CA R Tepee 500 North Rapids oa HARDING iver Quarry Exhibit Hall Inglesby R Harding Hole Rapids Dinosaur fossils SOB Rapids Echo Park Road warnin HOLE Desert Rapids CANYON Castle Park Overlook Vernal NTAIN high-clearance vehicles only; Voices OU Canyon Overlook Restricted access road SHUTTLES ONLY T M impassable when wet.
