Why Rockefeller secretly bought 35,000 acres, then donated them

In 1927, John D. Rockefeller Jr. quietly began buying large areas of land in Wyoming’s Jackson Hole through the Snake River Land Company. The company concealed Rockefeller’s involvement and eventually acquired more than 35,000 acres for $1.4 million. The land was later donated to the US government and became part of Grand Teton National Park.
