Yosemite National Park is a massive park in California. There are two main hotels in the park, the Ahwahnee, and the Wawona. There is also a dam that holds back a resevoir of water called the Hetch Hetchy Resevoir. This park is an icon of America, but what will happen to it without people?
1 day after people: Where almost 4,000,000 annual visitors camped and hiked, is now silent. Only the distant sound of the waterfalls can be heard.
5 years after people: Both hotels have suffered some damage over the years. Some windows have been blown out letting water and debris inside.
25 years after people: The Wawona Hotel hasn't lasted that long. Being made of wood and being exposed to the elements, termites and dry rot have attacked the building, causing parts of the veranda and roof to fall. Now, the main supports are starting to break. Finally, they snap, and the hotel collapses.
75 years after people: In the late 1980s, there was a huge wildfire that burned for about 3 weeks. Now, the Ahwahnee Hotel is in trouble. Lightning has started a large fire in the valley. With nobody to put it out, the fire burns unchecked, burning the hotel to the ground.
150 years after people: The area around Yosemite is seismically active, so they occasionally get earthquakes. The dam that holds back Hetch Hetchy Resevoir doesn't look much different, but, that will change. An earthquake shakes the park, cracking the dam down the sides and middle. As the ground shakes, the cracks get worse. The pressure of the water gets to be too much, and the dam breaks, flooding the surrounding area.
1000 years after people: Yosemite is pretty much the same. Nature has completety reclaimed the park, leaving no trace of human contact.
