Three reservoirs, named for corresponding dams on the Gunnison River, form the heart of Curecanti National Recreation Area. Panoramic mesas, fjord-like reservoirs, and deep, steep and narrow canyons abound. Blue Mesa Reservoir is Colorado's largest body of water, and is the largest Kokanee Salmon fishery in the United States. Morrow Point Reservoir is the beginning of the Black Canyon of the Gunnison and below, Crystal Reservoir is the site of the Gunnison Diversion Tunnel, a National Historic Civil Engineering Landmark. Recently discovered dinosaur fossils, a 5,000 acre archeological district, a narrow gauge train, and traces of 6000 year old dwellings further enhance the offerings of Curecanti.

Nestled in southern Colorado, North America's tallest dunes rise over 750 feet high against the rugged Sangre de Cristo Mountains. The wind-shaped dunes glow beneath the rugged backdrop of the mountains. This geologic wonderland, containing 30 square miles of dunes, became a national monument in 1932. With the passage of the Great Sand Dunes National Park and Preserve Act of 2000, resources now also include alpine lakes and tundra, six peaks over 13,000' in elevation, ancient spruce and pine forests, large stands of aspen and cottonwood, grasslands, and wetlands--all habitat for diverse wildlife and plant species.

Bent's Old Fort National Historic Site features a reconstructed 1840s adobe fur trading post on the mountain branch of the Santa Fe Trail where traders, trappers, travelers, and the Cheyenne and Arapaho tribes came together in peaceful terms for trade. Today, living historians recreate the sights, sounds, and smells of the past with guided tours, demonstrations and special events.

The California Trail carried over 250,000 gold-seekers and farmers to the gold fields and rich farmlands of California during the 1840's and 1850's, the greatest mass migration in American history. Today, more than 1,000 miles of trail ruts and traces can still be seen in the vast undeveloped lands between Casper Wyoming and the West Coast, reminders of the sacrifices, struggles, and triumphs of early American travelers and settlers. More than 240 historic sites along the trail will eventually be available for public use and interpretation. The trail passes through the states of Missouri, Kansas, Nebraska, Colorado, Wyoming, Idaho, Utah, Nevada, Oregon, and California.

The Pony Express National Historic Trail was used by young men on fast paced horses to carry the nation's mail across the country, from St. Joseph, Missouri to Sacramento, California, in the unprecedented time of only ten days. Organized by private entrepreneurs, the horse-and-rider relay system became the nation's most direct and practical means of east-west communications before the telegraph. Though only in operation for 18 months, between April 1860 and October 1861, the trail proved the feasibility of a central overland transportation route, and played a vital role in aligning California with the Union in the years just before the Civil War. Most of the original trail has been obliterated either by time or human activities. Along many segments, the trail's actual route and exact length are matters of conjecture. However, approximately 120 historic sites may eventually be available to the public, including 50 existing Pony Express stations or station ruins.

This site in Kiowa County is being developed to recognize the national significance of the massacre of about 150 Cheyenne and Arapaho people by 700 U.S. volunteer soldiers led by Colonel John M. Chivington.

Rocky Mountain National Park includes elevations ranging from 8,000 feet in the wet, grassy valleys to 14,259 feet at the weather-ravaged top of Long's Peak. Wildlife include elk, mule deer, moose, bighorn sheep, black bears, coyotes, cougars, eagles, hawks and scores of smaller animals. With 359 miles of trail, there are endless opportunities to hikers, backpackers and horseback riders. There are sixty peaks rising above 12,000 feet challenge intrepid hikers and climbers. Trail Ridge Road is the highest, continuous, paved road in the United States, topping out at 12,183 feet. RMNP is located between Estes Park and Grand Lake.

A beautiful mountain valley just west of Pikes Peak holds spectacular remnants of the earth's prehistoric life. Huge petrified redwoods and incredibly detailed fossils of ancient insects and plants reveal a very different Colorado of long ago. Almost 35 million years ago, enormous volcanic eruptions buried the then-lush valley and petrified the redwood trees that grew there. A lake formed in the valley and the fine-grained sediments at its bottom became the final resting-place for thousands of insects and plants. These sediments compacted into layers of shale and preserved the delicate details of these organisms as fossils. The Florissant Fossil Beds are world-renowned, and in 1969 were set aside as a part of our National Park System.

Mesa Verde, Spanish for "green table", offers an unparalleled opportunity to see and experience a unique cultural and physical landscape. The culture represented at Mesa Verde reflects more than 700 years of history. From approximately A.D. 600 through A.D. 1300 people lived and flourished in communities throughout the area, eventually building elaborate stone villages in the sheltered alcoves of the canyon walls. Today most people call these sheltered villages "cliff dwellings". The cliff dwellings represent the last 75 to 100 years of occupation at Mesa Verde. The archeological sites found in Mesa Verde are some of the most notable and best preserved in the United States. Mesa Verde National Park offers visitors a spectacular look into the lives of the Ancestral Pueblo people.

The Black Canyon of the Gunnison's unique and spectacular landscape was formed slowly by the action of water and rock scouring down through hard Proterozoic crystalline rock. No other canyon in North America combines the narrow opening, sheer walls, and startling depths offered by the Black Canyon of the Gunnison. The Canyon is located near Montrose.

Yucca House National Monument is a large, unexcavated Ancestral Puebloan surface site. Yucca House is located in Southwest Colorado between the towns of Towaoc and Cortez.

Santa Fe emerged as the hub of the overland continental trade network linking Mexico and United States markets—a network that included not only the Old Spanish Trail, but also the Santa Fe Trail and El Camino Real de Tierra Adentro. After the United States took control of the Southwest in 1848 other routes to California emerged, and use of the Old Spanish Trail sharply declined. Because of its rich history and national significance, the Old Spanish Trail has been designated as a national historic trail.

Between 1821 and 1880, the Santa Fe Trail was primarily a commercial highway connecting Missouri and Santa Fe, New Mexico. From 1821 until 1846, it was an international commercial highway used by Mexican and American traders. In 1846, the Mexican-American War began. The Army of the West followed the Santa Fe Trail to invade New Mexico. When the Treaty of Guadalupe ended the war in 1848, the Santa Fe Trail became a national road connecting the United States to the new southwest territories. Commercial freighting along the trail continued, including considerable military freight hauling to supply the southwestern forts. The trail was also used by stagecoach lines, thousands of gold seekers heading to the California and Colorado gold fields, adventurers, fur trappers, and emigrants. In 1880 the railroad reached Santa Fe and the trail faded into history.

Colorado National Monument preserves one of the grand landscapes of the American West. Sheer-walled canyons, towering monoliths, colorful formations, desert bighorn sheep, soaring eagles, and a spectacular road reflect the environment and history of the plateau-and-canyon country. Historic Rim Rock Drive offers 23 miles of breathtaking panoramic views and numerous overlooks. Trails lead across mesa tops and to spectacular overlooks or into backcountry canyons. Picnicking and camping are available. At an average elevation of 6,000 feet at the rim, the climate is relatively mild but can change rapidly to snow or summer storms. Around 275,000 people per year visit Colorado National Monument to enjoy these and other opportunities. The monument encompasses some 20,500 acres, and much of which has been recommended to Congress for designation as wilderness.

Dinosaur National Monument protects a large deposit of fossil dinosaur bones--remains of the so-called "terrible lizards" that lived millions of years ago. The dinosaurs weren't really lizards, and most of them weren't even terrible. But some of the first dinosaur fossils ever found were huge bones and teeth, very lizard-like except for their size, and so the idea of monstrous lizards was born. Today, many ideas about dinosaurs are changing, and the fossils at Dinosaur National Monument continue to help us learn more about these fascinating animals. There is also more to Dinosaur National Monument than dinosaurs. The 210,000 acres within the park will grab your attention with its beauty, rugged wildness, solitude, and silence.
