44-626: The highway forms a diamond-shaped loop with vertices at Moab , Helper , Vernal and Grand Junction . Notable features along the Dinosaur Diamond include Dinosaur National Monument , the Flaming Gorge National Recreation Area , Canyonlands National Park , Arches National Park , Natural Bridges National Monument , Colorado National Monument , and several national forests. The path of Interstate 70 (I‑70) in Colorado

88-440: A case-by-case basis). To be considered for designation "a road or highway must significantly meet at least one of the six scenic byways intrinsic qualities". The qualities are scenic, natural, historic, cultural, archeological, or recreational. A "corridor management plan" must also be developed, with community involvement, and the plan "should provide for the conservation and enhancement of the byway's intrinsic qualities as well as

132-424: A consequence of this definition, the point where two lines meet to form an angle and the corners of polygons and polyhedra are vertices. The vertex of an angle is the point where two rays begin or meet, where two line segments join or meet, where two lines intersect (cross), or any appropriate combination of rays, segments, and lines that result in two straight "sides" meeting at one place. A vertex

176-479: A market for agricultural products. Moab residents pushed for a road to be built along the riverbank. By 1902, the trail was replaced with a toll road, called King's Toll Road, after Samuel King. King was an early settler who also operated the toll ferry used prior to the construction of the Dewey Bridge . Rocks inscribed with "Kings Toll Road" can still be found along the roadway. While the road did improve travel, it

220-409: A polygon are points of infinite curvature, and if a polygon is approximated by a smooth curve, there will be a point of extreme curvature near each polygon vertex. A vertex of a plane tiling or tessellation is a point where three or more tiles meet; generally, but not always, the tiles of a tessellation are polygons and the vertices of the tessellation are also vertices of its tiles. More generally,

264-478: A simple polygon P is called an ear if the diagonal [ x (i − 1) , x (i + 1) ] that bridges x i lies entirely in P . (see also convex polygon ) According to the two ears theorem , every simple polygon has at least two ears. A principal vertex x i of a simple polygon P is called a mouth if the diagonal [ x (i − 1) , x (i + 1) ] lies outside the boundary of P . Any convex polyhedron 's surface has Euler characteristic where V

308-648: A state highway in 1910. The southwest end was moved from Colton to Castle Gate in 1912, and in 1927 it was numbered State Route 33. Few changes were made to the roadway, and in 1981 it became part of US 191. Access between Moab and Castle Valley was originally via a pack trail called the Heavenly Stairway. This trail, named for a dramatic descent of over 1,000 feet (300 m), was described as beautiful, but difficult to navigate. Isolated from Utah's population centers, this area depended on Grand Junction and other cities in Colorado for both everyday supplies and

352-534: A tessellation can be viewed as a kind of topological cell complex , as can the faces of a polyhedron or polytope; the vertices of other kinds of complexes such as simplicial complexes are its zero-dimensional faces. A polygon vertex x i of a simple polygon P is a principal polygon vertex if the diagonal [ x (i − 1) , x (i + 1) ] intersects the boundary of P only at x (i − 1) and x (i + 1) . There are two types of principal vertices: ears and mouths . A principal vertex x i of

396-449: A walkway where visitors can view a sandstone wall embedded with over 2,000 dinosaur bones, and watch paleontologists chip away the sandstone to expose the fossilized dinosaur bones. Visitors can also see the preparation laboratory where dinosaur fossils are cleaned and preserved. Upon leaving Dinosaur, the DD continues west on US 40 and crosses the border into Utah. The Utah portion of

Within Green River, US 191 converges with I-70 for a short while and diverges again, south towards the city of Moab, 55 miles (89 km) from Green River. Just south of the junction of US 191 and SR-128, the city of Moab features a number of nearby attractions. Arches National Park , Canyonlands National Park , Dead Horse Point State Park , and

484-404: Is a corner point of a polygon , polyhedron , or other higher-dimensional polytope , formed by the intersection of edges , faces or facets of the object. In a polygon, a vertex is called " convex " if the internal angle of the polygon (i.e., the angle formed by the two edges at the vertex with the polygon inside the angle) is less than π radians (180°, two right angles ); otherwise, it

528-692: Is a popular recreational feature located at the Flaming Gorge Reservoir within Ashley National Forest. It is in Flaming Gorge, a partially submerged canyon on the Green River . The National Recreation Area contains 207,363 acres (839 km ) of both land and water, which is divided almost evenly in Utah and Wyoming. The canyon was named by explorer John Wesley Powell , who upon first looking at

572-402: Is called "concave" or "reflex". More generally, a vertex of a polyhedron or polytope is convex, if the intersection of the polyhedron or polytope with a sufficiently small sphere centered at the vertex is convex, and is concave otherwise. Polytope vertices are related to vertices of graphs , in that the 1-skeleton of a polytope is a graph, the vertices of which correspond to the vertices of

616-492: Is derived from two previous highways, U.S. Highway 6 (US 6) and US 40 . US 40 was an original piece of the U.S. Highway system commissioned in 1926. The portion now numbered US 6 came about in 1937 when the route over Vail Pass was paved. The first route through the path of I-70 in Utah was the Old Spanish Trail , a trade route between Santa Fe, New Mexico , and Los Angeles, California . The trail

660-771: Is part of the Uinta Mountain range. The Uinta Mountains are one of the few mountain ranges in the contiguous United States which run east–west, and are the highest range to do so. Within Duchesne, US 40 and US 191 diverge, and the DD continues 55 miles (89 km) south along US 191 over an unnamed mountain pass , through the small town of Helper, and into the larger city of Price . The numerous attractions surrounding Price include College of Eastern Utah Prehistoric Museum , Manti-La Sal National Forest , Huntington Lake State Park , Scofield State Park , and Ninemile Canyon which features numerous petroglyphs. Also nearby

704-593: Is the Cleveland-Lloyd Dinosaur Quarry , a prehistoric mud trap which claims to be the densest concentration of Jurassic dinosaur fossils in the world. Traveling 63 miles (101 km) southeast along US 191, the DD encounters the city of Green River. Notable features surrounding Green River include the San Rafael Swell , Green River State Park , and Goblin Valley State Park . Also nearby

748-448: Is the number of vertices, E is the number of edges , and F is the number of faces . This equation is known as Euler's polyhedron formula . Thus the number of vertices is 2 more than the excess of the number of edges over the number of faces. For example, since a cube has 12 edges and 6 faces, the formula implies that it has eight vertices. In computer graphics , objects are often represented as triangulated polyhedra in which

792-534: The American Association of State Highway Officials (AASHO) assigned the designation of US 40 to this cross-state route, consisting of most of SR-4 and all of SR-6. (The SR-6 designation remained until the 1977 renumbering ; SR-4 became SR-2 in 1962 and was eliminated in favor of I-80 in 1977.) The road connecting Colton on SR-8 (US 50, now US 6) with SR-6 (US 40) in Duchesne became

836-695: The Ashley National Forest . Continuing along the Dinosaur Diamond, US 40 and US 191 converge within Vernal, heading west for 30 miles (48 km) to the city of Roosevelt . Roosevelt is located on the edge of the Uintah and Ouray Indian Reservation . Heading 29 miles (47 km) to the west is the county seat of Duchesne , located within the reservation. Nearby Duchesne are Fred Hayes State Park at Starvation and Kings Peak (the highest point in Utah), which

The byway continues 18 miles (29 km) northwest on SH-64, to the small town of Dinosaur. Nearby Dinosaur is the "crown jewel" of the DD, the Dinosaur National Monument , which claims to be the most productive Jurassic Period dinosaur quarry in the world. The monument includes

924-519: The Gulf of Mexico for his business. General Ashley and his team began making their way up the Green River (one of the many bodies of water located in the forest) in the spring of 1825. After passing through the Flaming Gorge, General Ashley was convinced by the native Americans to turn around and head back up the Uinta Mountains. During his exploration, General Ashley wrote and hung his name out over one of

Hundreds of lakes, streams, and meadows can be found within the many basins located in the mountain range. The Uinta Mountains are also the home to many different types of wildlife including, elk , moose , mule deer , coyotes , black bears , ptarmigan , several raptor species, beavers , marten , river otters , mountain goats , bighorn sheep , pronghorn , cougars , pikas , and marmots . The mountains also contain 16 designated trails (545 miles [877 km]) for visitors to explore from June to September. The Flaming Gorge National Recreation Area

1320-423: The forest called Yurts that provide cross-country skiers with overnight room rentals to escape the cold. There are also many lakes and rivers found throughout Ashley National Forest, which allows guests to take in some fishing while visiting. There are also some bodies of water in the forest that are designated for motorized water-crafts. The John D. Dingell Jr. Conservation, Management, and Recreation Act created

1364-410: The forest contains over 1,000 miles (1,600 km) of hiking trails. These trails cover the entire forest, taking hikers from extensive forests to rugged mountains. Many of these trails are designated for off-road vehicles as well, such as motorcycles, ATVs , and snowmobiles . Along the trails there are many campgrounds available to visitors. During the winter months, there are two facilities located in

1408-477: The forest suggest that the land had been hunted for centuries by native Americans before the arrival of Europeans. The first white men believed to have set foot in Ashley National Forest were the Spanish explorers Dominques and Escalante , in 1776. The forest, however, was not thoroughly explored until the early 19th century when General William Henry Ashley , an organizer of a fur company, began looking for an outlet to

1452-485: The forest when he established the Flaming Gorge National Recreation Area as part of Ashley National Forest in 1968. Since then, there have only been slight boundary changes to the forest. The forest contains four main byways to drive on, which take visitors through many different landmarks found in the forest and offers them a chance to see various forms of wildlife. For people who prefer to walk,

1496-837: The most popular landmarks located in the forest include the Flaming Gorge National Recreation Area and the Uinta Mountains , which contains the highest mountain peak in Utah ( Kings Peak ). The forest also includes 276,175 acres (1,117.64 km ), or about 60.5%, of the High Uintas Wilderness (with the rest being in the Wasatch–Cache National Forest ). The headquarters for the Ashley National Forest are located in Vernal, Utah with ranger district offices in Vernal; Duchesne, Utah ; Roosevelt, Utah ; Manila, Utah ; and Green River, Wyoming .

The path of I-70 in Colorado is derived from two previous highways, US 6 and US 40 . US 40 was an original piece of the U.S. Highway system commissioned in 1926. The portion now numbered US 6 came about in 1937 when

1628-607: The red gorge believed that it was on fire. In 1962 the Flaming Gorge Dam was completed, impounding the Green River to create the Flaming Gorge Reservoir. The reservoir is extremely popular for boaters, with five full-service marinas offering launching, storage, and maintenance facilities. Because the reservoir's water remains cool even in summer's extreme heat, it is popular with water sports enthusiasts. The reservoir and Green River upstream are known for supporting

1672-515: The rivers that he had explored, which now lies below the water of the Flaming Gorge Reservoir ; this is how Ashley National Forest received its name. Many other explorers would come and explore the forest, and eventually the first settlement in Ashley National Forest was made in 1872. It was settled by Captain Pardon Dodds, who brought about 2,000 cattle into the Uintah Basin . In a few years, all of

1716-547: The route over Vail Pass was paved. A portion of this route was also numbered US 24 at the time. In the 1920s, SH-139 was an unimproved road from US 6 at Fruita north to SH-64 in Rangely. The first route through this portion of Utah was the Old Spanish Trail , a trade route between Santa Fe, New Mexico and Los Angeles, California . The trail was in common use before the Mexican–American War in 1848. Although

1760-633: The surrounding ranges were completely stocked with cattle and horses. On July 1, 1908, by executive order of President Theodore Roosevelt , Ashley National Forest was created. The general boundaries of the forest remained unchanged until 1953. Most of the north slope of the Uinta Mountains was transferred to the Wasatch National Forest , while Ashley National Forest received the Rock Creek and Duchesne River drainages. President Lyndon B. Johnson added approximately 120,000 acres (486 km ) to

1804-508: The trail serves a different route than I-70, they were both intended to connect southern California with points further east. I-70 generally parallels the route of the Old Spanish Trail west of Crescent Junction. The Utah State Road Commission took over US 40 from Kimball Junction to Colorado in 1910 and 1911, and assigned the SR-6 designation to this route by the mid-1920s. In late 1926,
