Bison (American Buffalo) can weigh up to 2,000 lbs and can sprint or stampede at speeds around 30 – 40 mph. Bison can also jump 6 feet straight up in the air, over fences. They are wild animals in a domesticated setting at Yellowstone National Park, the only free-roaming herds of bison in the United States. There are about 4,000 American Buffalo at Yellowstone and despite the National Park Service warning visitors not to get too close, people get too tempted to capture that awesome photo and instead end up being gored. Yellowstone bison are also famous for ruling the roads, sometimes hip-checking, kicking or charging cars. With males being 2,000 pounds, there’s not much you can do other than wait them out if the bison are blocking the road. This is referred as the bison (or buffalo) traffic jam. Yellowstone National Park is the only place in the U.S. where bison have lived continuously since prehistoric times. Here’s a look at the bison of Yellowstone, buffalo traffic jams, and bison attacking cars and people. [55 Photos, 7 Videos]

Bonito is the heart of eco-tourism in Brazil because it is famous for its natural beauty, prehistoric caves, waterfalls, and clear blue waters. One of the most beautiful is Blue Lake Cave (Gruta do Lago Azul). Amazingly, it is believed that no human set foot inside the cavern with the cobalt blue waters until 1924 when an Indian from the Terena tribe discovered it. That’s not to say nothing ventured down into the 328 feet (100 meters) deep cave, since massive mammals fossils from about 10,000 years ago were discovered by cave divers, bones such as those belonging to the Saber-tooth tiger and giant ground sloth. Because the water is so clear, it is hard to fathom that Blue Lake Cave is about 295 feet (90 meters) deep. Adventurers start with a hike through the forest, then go caving through a wide entrance that allows sunlight to illuminate the gorgeous blue waters as well as stalactites and stalagmites of all different sizes. Here’s a look at Bonito, Mato Grosso do Sul, Brazil and some of the extraordinary and unusual ecotourism adventures and true natural treasures including beautiful Blue Lake Cave. [25 Photos]

President’s Day is always celebrated on the third Monday of February and the Mount Rushmore National Memorial, a sculpture carved into the granite near Keystone, South Dakota, seemed most appropriate to celebrate it. Each of the 60 foot sculpted heads were carved into the granite, mostly by blasting with dynamite, to depict U.S. Presidents George Washington, Thomas Jefferson, Theodore Roosevelt, and Abraham Lincoln. Together, these Founding Fathers represent the first 130 years of American history. [34 Photos]

Roses have been around for about 32 million years and it’s too true that “The rose speaks of love silently, in a language known only to the heart.” Roses are especially romantic, but if you ever give roses to someone, do you select the color based on that person’s favorite color, or yours? Or do you select roses based on the meaning and symbolism of the rose color? After hopping around on the web, it’s a bit confusing when you consider the diversity of meanings that rose colors can symbolize. Maybe if you can’t afford real roses, then you can send someone special this wide variety, a rainbow of colored virtual roses? [35 Photos]
