Colorado

**Colorado** is a state in the western United States. Its capital and largest city is Denver. Other large cities are Colorado Springs and Aurora. Colorado became the 38th state admitted to the union on August 1, 1876.

## History
Native Americans were the first people to live in Colorado. Some important Colorado Native American peoples are the Navajo, Ute, and Cheyenne-Arapahoe Indians. The state was named after the Colorado River by Spanish explorers. US Army officer and amateur explorer Zebulon Pike was recruited by the United States government in 1806 to find the source of the Mississippi River and to check out Spanish settlements in New Mexico. Even though his recorded location for the source of the Mississippi was wrong and he allegedly got lost in his expedition, he did explore much of what would become the American Southwest. When he reached what is now Colorado Springs, he named a mountain after himself, Pikes Peak, which remains a symbol for the city as well as the state to this day. 

Colorado has a long history of mining and digging for gold. It is the place where the Pike's Peak Gold Rush took place. When gold in California was becoming harder and harder to find, people came to Colorado in large numbers when gold was discovered there in 1859, ten years after the California Gold Rush began. Many mining camps set up in Colorado would later become cities, such as Denver City and Boulder City. The motto for the gold rush was "Pike's Peak or Bust".

## Geography
The State of Colorado is shaped like a rectangle. The borders are latitude and longitude lines. The four borders are at 37°N, 41°N, 102°03'W, and 109°03'W. (The east and west borders are 25°W and 32°W from the Washington Meridian.) Colorado, Wyoming, and Utah are the only three U.S. states that have only lines of latitude and longitude for boundaries and that have no natural borders. When government surveyors made the border markers for the "Territory of Colorado", minor surveying mistakes made many small  along the borders, most seen along the border with the "Territory of Utah."

The tip of Mount Elbert at 14,440 feet (4,401&nbsp;m) elevation in Lake County is the state's highest point and the highest point in the entire Rocky Mountains. Colorado has more than 100 mountain peaks that reach over 4,000 meters (13,123&nbsp;ft) in height. Colorado is the only U.S. state that lies  above 1,000&nbsp;meters (3,281&nbsp;ft) in height. Colorado has the highest average elevation of any state at 6,800&nbsp;ft. It borders New Mexico, Arizona, Utah, Oklahoma, Kansas, Nebraska, and Wyoming.

The land area of Colorado is roughly the same size as New Zealand.
