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.
