It is the principal city of the Grand Junction Metropolitan Statistical Area which had a population of 146,723 in 2010 census.
The city is located along the Colorado River, where it receives the Gunnison River from the south. The name "Grand" refers to the historical Grand River, which was renamed the upper Colorado River in 1921, and the word "Junction" is from the joining of the Colorado and Gunnison rivers. Hence, Grand Junction has been given the nickname "River City". The city sits near the midpoint of a arcing valley, known as the Grand Valley, a major fruit-growing region, historically home to the Ute people and settled by white farmers in the 1880s. In recent years, several wineries have been established in the area as well. The Colorado National Monument, a unique series of canyons and mesas, overlooks the city on the west, while most of the area is surrounded by public lands managed by the Bureau of Land Management. The Book Cliffs are a prominent series of cliffs that define the northern side of the Grand Valley. Interstate 70 connects the city eastward to Glenwood Springs and Denver and westward to Green River, Utah; Salt Lake City (via Interstate 70 and U.S Route 6); and Las Vegas (via Interstate 70 and Interstate 15)
The Country Jam Ranch is located near Grand Junction just north of I-70 at the Mack exit. This is a permanent festival site built for music festivals, including Country Jam, an event that has been held since 1992 and one that draws thousands of country music fans to the area.
