Yellowstone River Is An Example Of Changing Biodiversity
The Yellowstone River is the longest undammed river in the United States. It originates at 12,800 feet above sea level in the Absaroka Mountains of Wyoming. Flows north into Montana, turns east at Livingston, and by the time it reaches the Missouri River in the plains of western North Dakota, the river has descend 11,000 feet to a mere 1,800 above sea level. The biodiversity of the Upper Yellowstone River is drastically different than that of the lower regions. But as our climate changes, species are finding new homes.
