Teton mountain range at sunrise, WY

Located in Wyoming, this mountain range began forming 6-9 million years ago.  The Tetons are the youngest mountains in the Rocky Mountain range.

It is a unique mountain range due to its formation, and we had a mountain experience of an unusual nature.

A series of geological processes over millennium eventually led to the uplift of the region.  Situated on the Teton Fault, approximately two million years ago earthquakes displaced the range.

The western side moved upward while the eastern side moved downward creating the Teton Range and Jackson Hole valley, respectively.

Most mountain ranges have foothills which often obscure much of the mountain.  But here the eastern side arose so quickly and sharply that there are no foothills.  In addition, the older the range is, the more eroded the peaks become.
