History of the Grand Valley

Home| Bangs Canyon Home| Grand Mesa Home

The Grand Valley is a beautiful and vibrant area that provides wonderful learning opportunities in science. Situated along the Colorado and Gunnison Rivers, the Grand Valley is surrounded by three major geological features: The Bookcliffs (northwest), Grand Mesa (east), and Colorado National Monument (southwest). These natural areas, along with the Colorado and Gunnison Rivers, are rich resources to learn about ecosystems, biology, and geology. Along with teaching students to appreciate the scientific opportunities the Valley offers, it is important that they understand the history of this region. Much has happened in Mesa County over the ages to shape the present environment.

Over time, geological events shaped the Valley into what we see today, although at one time it was vastly different. Large seas that dried up over time, mountains that uplifted (formed) and eroded away, lava flows, and climate changes are responsible for the unique landscape of today. During the late Jurassic Period, the valley was a large flood plain with lush conifers and cycads (palm-like plants) over an understory of ferns. This was the time of dinosaurs like Bracchiosaurus, Apatosaurus, Allosaurus, and Stegosaurus (the Colorado State Fossil). Remains of these large creatures can now be found throughout the valley, generally in the Morrison formation. Their bones have been carefully preserved throughout the ages because of mud and volcanic activity which quickly covered and buried their bodies soon after death. Many locations in the Valley have yielded wonderful samples of dinosaur skeletons that were probably deposited into ancient lakebeds by rivers.

PetroglyphsLong after the dinosaurs, the area was home to Fremont Indians who were most likely the area's first inhabitants. They are speculated to have occupied the land from about 250 AD to 1300 AD, when they mysteriously disappeared. Evidence of their existence can be found in the form of petroglyphs (rock art carvings) and pictographs (paintings).  

After the Fremont left, Ute Indians were the next to call the Valley their home. They were nomadic hunters who migrated into this land sometime between 1300 AD and 1500 AD. Quickly after Spaniards introduced horses to the Native Americans, the Utes became excellent horsemen and were feared as mighty warriors.

The Domiguez-Escalante expedition explored this region in 1776 and became probably the first Europeans to set foot in this beautiful desert and mountain land. During the friars' expedition, the Spanish Crown ruled this area and closed it to exploration by Americans. In 1821, however, Spain gave up its claim to much of the American West and the Grand Valley region became part of Mexico. Mexican officials opened the land up to adventurous mountain men, trappers, and traders. Along with the mountain men came famous explorers in the 1820s-1840s like Kit Carson and Antoine Robidoux. Robidoux built Fort Umcompahgre (then known as Fort Robidoux) near the present Mesa-Delta County lines.

Survey spikeIn the 1850s, U.S. Army exploration parties lead by Captains John Gunnison, John C, Fremont, Marcus Whitman, Edward Beale, and others began exploring this region. Then between 1873 and 1876, the U.S. Geological Survey mapped the Grand Valley under the direction of Ferdinand Hayden.

In 1868, a treaty was formed between the U.S. Government and the Ute Indians that designated the Grand Valley as part of the Ute reservation. The land here was very desirable to settlers, though, and pressure was applied to remove the Indians to provide more land for pioneers.

In 1876, Colorado gained statehood and soon settlers began moving into the valley. Clashes between the settlers and Native Americans sprang up causing more and more tension between the Ute Tribe and the government. The most famous conflicts happened in 1879, the Meeker Massacre and the Battle of Milk Creek. Although both were small battles, they were very violent, and in 1880 another treaty was signed by the Ute Tribe with the U.S. Government. This time, the Utes were forced off their land onto reservations in northeast Utah and southwest Colorado. September 4,1881, was the last day of Indian removal from this area and already pioneers had gathered in Gunnison waiting to settle the Valley.

After the last Utes had left, settlers began pouring into the area. One of the first was Grand Junction founder, George A. Crawford. He is probably responsible for Grand Junction's name, located at the junction of the Grand (now Colorado) and Gunnison Rivers. In June of 1882, the City of Grand Junction was officially established. Shortly thereafter, in November 1882, the Denver and Rio Grande Western Railroad (D&RG) laid down tracks through the small western town. D&RG soon became the area's largest employer, connecting the Valley with Gunnison and Denver. Grand Junction and surrounding areas began to grow and soon other areas were also settled: Fruita, Orchard Mesa, the Redlands, Glade Park, Loma, Mack, and Carpenter.

Before long, the Grand Valley was home to lawyers (W.J. Miller and James W. Bucklin), a doctor (Harrison Stroud) and a school with Nannie Blain as its first schoolmarm. Saloons, blacksmiths, livery stables, hotels, ice houses, a newspaper, and lumber mills were built to provide services to settlers. Jim Davis became Grand Junction's first town marshall in 1882, and in 1883 a volunteer fire department was established. Also in 1883, the first National Guard unit in Mesa County was established under the name of Company F, Grand Valley Guards. In May of 1897, the Grand Mesa Women's Club helped found the Grand Junction Public Library, and with help from Andrew Carnegie, the library was built in 1901.

Agriculture has always been a big part of life in the Grand Valley. Agriculturally dependent companies like stockyards, sugar manufacturers, chemical spray companies, and canning companies thrived at the turn of the Century. Irrigation was extremely important and construction on many canals began. These canals transported water from the Grand Mesa and Colorado River to Grand Junction and outlying areas.

Dinosaur bones were found in 1900 and 1901 leading to the development of popular fossil sites like Riggs Hill (named after a paleontologist from Chicago) and Dinosaur Hill. Mesa County is an exciting place to learn about these extinct giants and some of the world's largest and smallest dinosaur fossils have been found here. Throughout the 20th century, the Grand Valley continued to grow. More than one hundred years later, Mesa County continues to thrive and draws tourists and outdoor lovers to its beautiful mesas and monuments.
