This is a cathedral, my cathedral.

In this forest is the quietest place

in the entire United States,

and it's only one square inch in size.

My mission is to keep it that way.

I'm Gordon Hempton.

I'm a sound tracker.

I travel the globe in search of vanishing sounds,

including the most endangered of all,

which is simply silence.

Noise pollution is nearly inescapable.

The Hoh Valley is the quietest,

least noise-polluted place in the entire lower 48.

I don't know if I can save silence,

but I know that I can try.

So it was 12 years ago, 2005 Earth Day,

that I hiked up the Hoh River Valley.

It took three miles just to escape

the noise of the parking lot.

That's when I was looking in every direction

for which way I should go.

I saw the elk trail, love to follow their advice

because they love quiet just like I do;

and they led me right to the spot.

It's just through that tree, then off into the woods.

I defend this one square inch of silence

by doing both quiet and noise monitoring.

When a noise intrusion occurs,

I locate the noise maker,

send them a letter, and ask for compliance.

This matter is urgent.

Within ten years, it's likely that there will be

no quiet places left unless we take action.

When I first started, I did not think

silence would go extinct in my lifetime;

and if that happens, the quiet will disappear

and the wildlife will be devastated.

The One Square Inch of Silence foundation

is pressing our politicians to pass a single piece

of legislation that will designate Olympic National Park

as the world's first quiet park, off-limits to aircraft.

All things are possible.

The Earth is here and it's beautiful;

and, for me, it all starts here in the Hoh Valley.
