Springtime can only mean one thing for Yellowstone National Park: The newborn baby animals are coming out to play.

The National Park Service (NPS) has temporarily closed the Sol Duc Falls area in the Olympic National Park after an 18-year-old man fell over a 50-foot waterfall on June 8. The species has been in decline for thirty years, facing a 60% decrease within that time.

The National Park Service as a whole saw a record number of 331.9 recreation visits last year. Of the 63 NPS sites designated specifically as national parks, Yellowstone was the fourth most visited.
