US national park service to receive $100m in largest grant in its history

Donation from Indianapolis-based Lilly Endowment will be used across country's more than 400 national park sites

The official non-profit organization of the US national park service is set to receive the largest grant in its history, a $100m gift the fundraising group described as transformative for the country's national parks.

The National Park Foundation, which Congress created in the 1960s to support national parks, will receive the donation from the Indianapolis-based foundation Lilly Endowment Inc. The park foundation described the gift on Monday as the largest grant in history benefiting US national parks.
