Why so many things near Grand Junction say 'Grand'
Grand Junction, the Grand Valley, and Grand Mesa carry a name from the river that was once called the Grand before it became part of the Colorado River.

Around Grand Junction the word “Grand” shows up everywhere — the city, the valley, the big flat-top mountain. The name comes from a river.
The major river running through town was long known as the Grand River. “Grand Junction” marks the place where it meets the Gunnison River — a junction of two big rivers. The Grand Valley and Grand Mesa took their names from the same source. Later, the Grand River’s name was folded into the Colorado River, so the river label changed even though all the local “Grand” names stuck.
Why care: it is a small key to the map. Once you know the river story, the cluster of “Grand” names stops looking random and starts telling you how the place was settled and oriented.
