Grand Tetons,Wyoming

earth science

By Chelsea Jones


The Grand Teton national park was founded Sept 14,1950. It's located
just outside of Jackson Hole, Wyoming. The Teton mountain range is the youngest
range in the rockies. It's also an active fault-block mountain front. The range is
forty miles long and 7-9 miles wide. The highest peak is called "Grand Teton" and it's 13,770 ft high.

The Tetons were formed when two rectangular
blocks of the earth's crust moved like trapdoors, one swung skyward to form the mountains,
the other hinging downward to create the valley. Wind, rain, ice and glaciers constantly
eroded the growing range. Meanwhile enormous glaciers and meltwaters flowed southward
carrying gravel, coarse sand and re-lowering the floor of the valley.

Grand Teton National Park, as well as being an interesting geological study,
is also a great place to visit and vacation. It's a semi-arid mountain climate with an
extreme high of 93 degrees and an extreme low of -46 degrees. Activities include
hiking, walking, wildlife viewing, climbing, fishing, swimming, boating, biking
and in the winter skiing , snowshoeing, and snowmobiling.
