North Park is a high, sparsely populated basin (approximately 8800 ft in elevation) in the Rocky Mountains in north central Colorado in the United States. It encompasses a wide valley in Jackson County rimmed by mountain ranges at the headwaters of the North Platte River and several smaller tributaries, including the Michigan River, Illinois River, and Canadian River. The valley receives its name from being the northernmost of the three large mountain valleys (or parks) in Colorado on the western side of the Front Range. The others are Middle Park and South Park respectively.
The basin opens out northward into Wyoming, in the direction of flow of the North Platte. On the east side, it is rimmed by the Medicine Bow Mountains, the Never Summer Mountains and Rabbit Ears Range to the south, and the Park Range to the west. The continental divide rims the Park along the south and west. The primary economic activities in the valley are cattle ranching and timber harvesting, although the latter has declined substantially in recent decades. The largest community in the valley is Walden, the Jackson County seat, that sits near the middle of the valley near the confluence of the Michigan and Illinois rivers. Smaller communities in the valley include the unincorporated hamlets of Gould and Rand.
