John D. Rockefeller, Jr. Memorial Parkway
Located at the heart of the Greater Yellowstone Ecosystem, the Rockefeller Parkway connects Grand Teton and Yellowstone national parks. The late conservationist and philanthropist John D. Rockefeller, Jr. made significant contributions to several national parks including Grand Teton, Acadia, Great Smoky Mountains, and Virgin Islands.
In 1972 Congress dedicated a 24,000-acre parcel of land as John D. Rockefeller, Jr. Memorial Parkway to recognize his generosity and foresight. Congress also named the highway from the south boundary of Grand Teton to West Thumb in Yellowstone in honor of Rockefeller.
The parkway provides a natural link between the two national parks and contains features characteristic of both areas. In the parkway, the Teton Range ramps down a gentle slope at its northern end, while rocks born of volcanic flows from Yellowstone line the Snake River and form outcrops scattered atop hills and ridges.
Grand Teton National Park administers John D. Rockefeller, Jr. Memorial Parkway.
Did You Know?
Did you know that a large fault lies at the base of the Teton Range? Every few thousand years earthquakes up to a magnitude of 7.5 on the Richter Scale signal movement on the Teton fault, lifting the mountains skyward and hinging the valley floor downward.
