Answer:
Meander cutoff
Step-by-step explanation:
Oxbow Bend, which is part of Snake River in Grand Teton National Park is a meander river. A meander is a river that follows a series of curves, bends or loops in its watercourse. However, when one of these loops or curves becomes cut off from the rest of the river, but remains filled with water, it is known as a meander cutoff.
