What You'll See From the Top of the Empire State Building
The Empire State Building is a 102-story art deco skyscraper in New York City, New York at the intersection of Fifth Avenue and West 34th Street. Its name is derived from the nickname for the state of New York. It stood as the world's tallest building for more than forty years, from its completion in 1931 until construction of the World Trade Center's North Tower was completed in 1972. Following the destruction of the World Trade Center in 2001, the Empire State Building again became the tallest building in New York City.

World's largest open pit iron ore Mine - Hibbing, Minnesota

There are varying estimates about how much rock and ore have been removed from this mine since it started operations in 1895, but it's somewhere around 2 billion tons. This is equivalent to the amount of earth you'd have to move if you dug a tunnel 24 feet in diameter through the entire earth. Originally, there were 30 separate mines, but these were consolidated into a single operation at the turn of the century. By 1901, this facility was managed by J.P. Morgan, and during the peak production period in the early 1940s, nearly a quarter of all iron ore mined in the United States came from the Hull Rust Mine.
- World's largest open pit iron ore mine
- First ore shipments in 1895 (still being mined today, 100 years later)
- Originally 30 separate mines
- Total area: 1,591 acres
- Total length: 3 1/2 miles
- Greatest width: 1 1/2 miles
- Greatest depth: 535 feet
- Total ore shipped: About 1 billion tons Total rock removed: About 2 billion tons (that's 4 trillion pounds!)

Strange storm in Iowa
On a recent crisp autumn afternoon in Iowa, video cameras captured an unusual and visually dramatic result of two air masses colliding. Clouds split into a series of stripes and swept across the sky.
These so-called undular bores are created by atmospheric conditions that destabilize the air in a particular way. In the case of Des Moines, Iowa, they formed on Oct. 3 when a group of thunderstorms approached the city.
"At the time, a layer of cold, stable air was sitting on top of Des Moines," said atmospheric scientist Time Coleman of the National Space Science and Technology Center in Alabama. "The approaching storms disturbed the air, creating a ripple akin to what we see when we toss a stone into a pond."
A time-lapse video of the event shows just how strange it looked.
Undular bores are a type of gravity wave, one in which gravity is the force that pulls the wave down. Coleman likens the cloud waves to those created when a boat moves across the water.
"When a boat goes tearing across a lake, water in front of the boat is pushed upward," he explained. "Gravity pulls the water back down again and this sets up a wave."
The thunderstorms played the role of the boat in the skies over Des Moines in early October.
On radar images, the bores show up as bands denoting waves moving toward the radar and away from it. Coleman noted that residents of Des Moines actually felt the back-and-forth breeze as the waves traveled overhead.
"Flags flew one way during the crest of the wave and swung around 180 degrees to fly in the opposite direction during the trough," Coleman said.
The waves of undular bores typically measure 5 miles from peak to peak and race across the sky at 10 to 50 mph. Coleman estimates that one passes over any given point in the United States about once a month.
Undular bores can go on to form thunderstorms themselves.
"These waves churn up the atmosphere, causing instabilities that can initiate and sustain severe storms," Coleman said.
Of particular concern is the waves' ability to amplify tornadoes as they pass through the atmosphere, which is exactly what happened when an F5 (the strongest classification of tornado) struck right outside Birmingham, Alabama, in April 1998.
"At first the tornado was doing relatively little damage," Coleman recalled. "But our research shows that just before the tornado reached Birmingham, it was hit by an undular bore," causing it to spin up and increase in both intensity and size. The tornado went on to destroy more than 1,000 homes and businesses and caused $200 million in damage.

Enormous Spider Web Found In Texas

“When I first saw it,” said Park Superintendent Donna Garde, “I was totally amazed. What ran through my mind was that this looked like something out of a low-budget horror movie, but I was looking at something five times as big as what you’d see on a Hollywood set.”
Stumped as to the web’s origin, the initial consensus of arachnologists and entomologists who saw an online photo of the web sent by Texas Parks and Wildlife Department biologist Mike Quinn was that it may have resulted from a “mass dispersal” event. In such an event, millions of tiny spiders or spiderlings spin out silk filaments to ride air currents in a phenomenon known as “ballooning.”
Quinn collected a sample of spiders Aug. 31 from in and around the gigantic web and took them to Texas A&M University in College Station for analyses. Entomology Department researcher Allen Dean identified 11 spider families from the sample. The most prevalent species was the Tetragnatha guatemalensis, or what Quinn dubbed the Guatemalan long-jawed spider, since this species didn’t have a common name. Guatemala was the country in which it was first documented.
“I drove 50 to 100 spiders to A&M on Saturday,” Quinn said. “Spider experts tend to specialize in one or few families of spiders. There are nearly 900 species of spiders known from Texas, so no one is an expert on all the species.”
Quinn described the Lake Tawakoni web as “sheet webbing” since it covers a large area of trees, which is more typical of a web spun by a funnel web spider rather than the classic Charlotte’s web, or orb web, like that produced by long-jawed spiders. He speculates that the park’s spider population exploded due to wet conditions this summer that resulted in an abundance of midges and other a small insects upon which the spiders feed.
The Guatemalan long-jawed spider ranges from Canada to Panama, and even the islands of the Caribbean. According to Quinn, the spider is about an inch in length with a reddish-orange head- and-thorax. Spiders, like mites and scorpions, are arachnids, a group of arthropods with four pairs of legs, saclike lungs and a body divided into two segments.
So popular was the monster Lake Tawakoni spider web phenomenon that it ran as the lead story in the Nation section of the Aug. 31 New York Times, and was the newspaper’s most e-mailed article that day. The nightmarish quality of the story prompted satirical takes on several Internet Web sites and led to national coverage on Fox News, the Discovery Channel, CNN and other networks. Quinn termed the degree of news coverage “remarkable.”
Dr. Norman Horner, a retired dean of the College of Science and Mathematics at Midwestern State University in Wichita Falls, was on his way to the park mid-week to study the “not very common” phenomenon, when he received a call from park staff telling him that a heavy overnight rainstorm had made the trail impassable and knocked down much of the giant web.
“So far,” Horner said, “we have been informed of webs of this nature occurring in Florida, California, Canada, Italy, Ohio and now Texas. In all cases, they appear to have been produced by tetragnathids, but have other species associated with them.”
Superintendent Garde said Sept. 5 that the crowds coming to see the wondrous creation had slowed to a trickle, and that they were not being allowed to access the nature trail due to the sloppy conditions.
“It was fun, but we were really tired,” Garde said. “The spiders are great little guys. They put our park on the map.”

Grand Canyon pictures

This canyon is a gift that transcends what we experience. Its beauty and size humbles us. Its timelessness provokes a comparison to our short existence. In its vast spaces we may find solace from our hectic lives.
The Grand Canyon we visit today is a gift from past generations. Take time to enjoy this gift. Sit and watch the changing play of light and shadows. Wander along a trail and feel the sunshine and wind on your face. Attend a ranger program. Follow the antics of ravens soaring above the rim. Listen for the roar of the rapids far below. Savor a sunrise or sunset.
