The city of Grand Junction is located along the Colorado River, where it welcomes the Gunnison River. The name "Grand" refers to the historical upper Colorado River and the word "Junction" is from the joining of the Colorado and Gunnison rivers. Thus, Grand Junction has been given the nickname "River City". The city is situated near the midpoint of a 30-mile valley, known as the Grand Valley, a major fruit-growing region making it a prime location for wineries. 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.
