When one thinks of Wyoming's national parks,  the Grand Teton National Park usually comes to mind.  No wonder, with it's mountain peaks rising so abruptly from the valley floor that  people below  have to stop and stare in silent disbelief.  Many outdoor enthusiasts come to the area for hiking, camping, fishing, wildlife and bird watching, and snow skiing.  Tourists also enjoy fine dining and shopping in the valley at Jackson Hole.

Establishment as a Park

Grand Teton National Park evolved through a complicated process requiring three separate acts of government and compromises.  Grand Teton National Park was first established in 1929 and included only the Teton Range and six glacial lakes at the base of the mountain.  In 1943, President Franklin Roosevelt  declared Teton National Forest acreage, Jackson Lake and a donation from John D. Rockefeller of 35,000 acres as the Jackson Hole National  Monument.  On September 14, 1950,  the original Park and the Jackson Hole National Monument, including the donation from Rockefeller, combined to form Grand Teton National Park's present day boundaries.
