It seems a little off-the-mark to celebrate a centennial for a place that is millions of years old. But February 26, 1919 was the day legislation was signed making Grand Canyon a national park.

The tension is greater because of both climate change and the fossil-fuel-friendly nature of the Trump administration.
Stephen Nash visits to lay out the struggle and the sides.
