1 . 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.

4 . They' re not the world' s tallest or longest bridges, but a string of river crossings made from tree roots are engineering wonders that contain lessons for modern architects.

The town of Cherrapunji in the Khasi Hills is credited with the world record for annual rainfall of over 75 feet! And in this rainy, wet climate, the rubber fig tree grows with abandon. The tree has a secondary root system that grows up above the ground floor and lets the tree easily grow on top of big stones and even out in the middle of streams. Long ago, the Khasis, a tribe in Meghalaya region, realized they could make use of these roots to their own advantage. By controlling and directing the secondary roots, they have created strong living bridges with which to cross streams and rivers by themselves.

To make a tree grow in a certain direction, the tribespeople use the trunks of a betel nut tree whose middle is got rid of, as a guidance system. The thin, tender roots of the rubber tree are placed so they grow in the direction of the tree trunk rather than fanning out. Eventually, the roots reach the other side of the river and grow into the soil. This process can take well over a decade before the bridge is fully functional and then over time the bridge grows and strengthens. Rocks are placed along the bridge' s sides to improve the footpaths.

Some of these bridges are over 100 feet long and can even support the weight of fifty or-more people at a time. These bridges are used daily by the people of the villages around Cherrapunji and a few are thought to be more than 500 years old. There is even a double decker bridge , known as the “Umshiang Double-Decker Root Bridge", which features two bridges grown right on top of each other. It is thought to be the only bridge of its kind.
