John D Rockefeller Memorial Parkway - http://www.nps.gov/jodr
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 tapers to a gentle slope at its northern edge, while rocks born of volcanic flows from Yellowstone line the Snake River and form outcroppings scattered atop hills and ridges.
Grand Teton National Park administers John D. Rockefeller, Jr. Memorial Parkway.
