Jackson Hole is the valley floor between the
Teton Mountain Range and the
Snake River, located along the border of
Wyoming and
Idaho. The name "hole" was used by early trappers or
mountain men, who primarily entered the valley from the north and east and had to descend along relatively steep slopes, giving the sensation of entering a hole. These low-lying valleys are surrounded by mountains and contain rivers and streams, which were good habitat for
beaver and other fur-bearing animals.
