1. Yellowstone is the largest active geyser field in the world. Old Faithful, a geyser, erupts about every 65-95 minutes. Old Faithful shoots a column of water 100-130 feet (30 - 40 meters) into the air.
WOW! 5 minutes and 49 seconds. Take the time to watch this.

2. In Yellowstone, there are 15 miles of boardwalk, 92 trailheads that access approximately 1000 miles of trails. Yellowstone is about 5% covered by water, 15% by grassland and 80% by forests.
3. Yellowstone has 1000 to 3000 earthquakes annually, virtually all of which are undetectable to people.
4. Allow me to return to the buffalo again. Yellowstone Park herd was estimated in 2015 to be 4,900 bison. I read that even though the species is formally called American bison, the "Patriarch of the Plains" is commonly referred to as the "buffalo", a term coined by early-day French explorers who called them "les boeufs." "Bison" is a Greek word meaning "ox-like animal." A bull can weigh up to 2,000 pounds (one ton) while a cow generally weighs half that. Most bison live 12-15 years, although a few have lived as long as 20 years.
This video is 6 minutes and 55 seconds. It's Saturday today and in France we have a long Pentecost Sunday weekend, because Monday is a holiday for many. And school is over; you're on holiday; you have time to watch this video! You won't regret taking the time. And this one has good subtitles! I've already watched it three times!
