5 . The country’s first national park, Yellowstone, is renaming one of its largest mountains to honor indigenous people after research revealed the man it had been named after helped lead a massacre (屠杀) against local tribes. As part of the park’s 150th anniversary, officials announced the 10,551-foot high peak formerly called Mount Doane is now First Peoples Mountain.
“It is a victory, yes. Is history being rewritten and retold truthfully? I hope so,” William Snell, executive director of the Rocky Mountain Tribal Leaders Council, told NPR. His group helped advise federal officials on the name change. In an email, Snell said the change to First Peoples Mountain couldn't have come at a better time as Yellowstone officials prepare for the park’s anniversary in August.
The peak—along a range on the eastern side of Yellowstone Lake—had been named after Gustavus Doane, who helped lead the Washburn-Langford-Doane exploration in 1870 that eventually led to the park getting federal protection.
But recently, historians uncovered Doane’s role in an attack that left at least 173 Native Americans dead. Known as the Marias Massacre, Doane carried out the attack over the killing of a white fur trader. In writings, Doane cast a favorable light on the attack and even showed off about it for the rest of his life, the National Park Service said last week.
The renaming to First Peoples Mountain is part of a trend to better recognize the roles and contributions of Native Americans. It has also become a priority of the nation’s first indigenous cabinet secretary—the Interior Department’s Deb Haaland, who oversees the National Park Service—and Charles SamsⅢ, the first Native American to serve as that agency’s director.
Across the American West, many iconic representative mountains and other environmental places were named after early white settlers, mostly men and some with terrible pasts.
In Yellowstone, park officials say they may consider further changes to derogatory (贬损的) or inappropriate geographical names in the months ahead.

6 . Balmoral Castle
Balmoral Castle, which started in the late 1300s. is the private residence of the Queen. It has remained a favourite residence for the Queen and her family during August and September.
Some 85,000 people visit Balmoral each year, and the estate maintains and restores footpaths throughout the property for visiting hikers.
Windsor Castle
Windsor Castle is an official residence of The Queen and the largest occupied castle in the world. The castle was the inspiration for the Royal family’s surname.
William the Conqueror built the castle in 1080 and it has remained a royal palace for over 900 years. Windsor is the oldest royal home in Britain and, covering 13 acres, it’s the largest castle in the world that is still lived in.
Each year, the Order of the Garter ceremony is held at Windsor Castle, and the Queen occasionally hosts a “dine and sleeps”, for politicians and public figures.
The Palace of Holyroodhouse
Founded as a monastery (修道院)in 1128, the Palace of Holyroodhouse in Edinburgh is The Queen’s official residence in Scotland. It was also the home of many Scottish royals.
The Queen holds receptions, state functions, and investitures(授职仪式)within its walls, and each year during Holyrood Week Queen Elizabeth and Prince Philip invite 8» 000 Scottish guests to the Garden Party.
St. James Palace
St. James’s Palace was built between 1531 and 1536 and was home of kings and queens of England for over 300 years. The palace was built by Henry VU on the site of the Hospital of St. James, Westminster. After the destruction by fire of the Palace of Whitehall in 1698, all monarchs until William W lived at St. James's for part of the time.

8 . Stephen Warren, study leader at the University of Washington, has been on the case of the green icebergs for more than 30 years. He first took samples from one of these green hunks of ice in 1988, near the Amery Ice Shelf, East Antarctic. Most glacial ice occurs in shades of white to brilliant blue. The bluer the ice, the older it is. Typically, compression (压缩)from accumulating layers of snow pushes air bubbles out of the ice, reducing the scattering of white light. The compressed ice absorbs most of the light except for blue, creating the blue color seen in the hearts of icebergs and glaciers.
The green ice was similarly bubble-free, and yet it looked green instead of blue. Warren and his team soon found that the green ice came not from glaciers, but from marine ice. That's the ice from the undersides of floating ice shelves.
At first, the team thought that organic material in the marine ice was causing the green color. But further research showed that the green marine ice didn't have a higher — than — usual amount of organic impurities. Now, a new study finds that a different sort of impurity may be the root cause of the green ice. Warren and his colleagues report that the marine ice at the bottom of the Amery Ice Shelf has 500 times more iron than the glacial ice above.
This iron comes from the rocks under the Antarctic Ice Sheet, which are turned into fine powder as glaciers move over them. The icebound iron oxidizes (氧化)as it contacts seawater. The resulting iron oxide particles take on a green color when light scatters through them. When icebergs break off the larger ice shelf, they carry this iron-rich ice with them. It's like taking a package to the post office. The iceberg can deliver this iron into the ocean far away, and then melt and deliver it to other living things that can use it as a nutrient.

9 . One of the most important creations of science is the invention of the lighthouses. Lighthouses help in a number of activities such as marking of the dangerous coastlines and directing safe entries to the harbours. The following are some famous lighthouses.
The Jeddah Light
It is located in Saudi Arabia. This lighthouse has been constructed very beautifully and adorns a beautiful structure. The Jeddah Light was built in 1990. This lighthouse is considered as the tallest of the world reaching a fine height of around 436 feet.
The Les Eclaireurs Lighthouse
It is addressed as the “lighthouse at the end of the world”. The Les Eclaireurs Lighthouse is located on a small island east of Ushuaia, the southernmost city of the world. This lighthouse was built in 1920 and today it has become a very famous tourist attraction in Argentina. However, visits to this lighthouse can be made only by boat.
The Peggys Point Lighthouse
Lit in 1915, it is an icon and a popular monument of Canada. The Peggys Point Lighthouse has become a major tourist sight and is considered as one of the busiest attractions in the area of Nova Scotia. This lighthouse also fetches you a wonderful scenic drive and visiting here, you can indulge yourself in the beauty of nature.
The Slettnes Lighthouse
It is the northernmost lighthouse that is located on the mainland of Europe and is considered as one of the most famous lighthouses of the world. This lighthouse is mostly considered as the North Cape Light and is the top lighthouse of Europe. The Slettnes Lighthouse firstly began to light in 1905. Though it was highly damaged during the World War Ⅱ by the Germans, yet it was restored and lit again. This lighthouse is very classic as to its looks.
