Trivia: In 1864, Lincoln signed an act protecting what present-day national park?
Death Valley
Yellowstone
Grand Canyon
Yosemite
The correct answer is Yosemite
So why is this answer correct? : On March 1, 1872, President Ulysses S. Grant signed the Yellowstone National Park Protection Act into law and formed the country’s first national park — but it wasn’t the first time a President protected America’s natural wonders. In 1864, Abraham Lincoln made the unprecedented decision to sign legislation giving Yosemite Valley to the state of California “for public use, resort, and recreation.”
