Take the free park shuttle to the Temple of Sinewava, walk one mile to the end of the paved walkway, and begin hiking up the river. Two hours upstream, at the intersection with Orderville Canyon, hikers will encounter the narrowest and most spectacular section of the Zion Narrows.
Photograph by Mike Segar, Reuters Second City is back in second place, at least when it comes to height. New York's One World Trade Center will officially open next year as America's tallest building, topping Chicago's Willis Tower by 325 feet (99 meters). The distinction hinges on a definition. According to the Council on Tall Buildings and Urban Habitat, the needle atop the new trade center is a spire, not an antenna.
In December 2014 Chicago Mayor Rahm Emanuel touted plans for a new tower in the Lakeshore East neighborhood that â if all goes according to plan â could reach 1,150 feet into the air by 2018. In 2013, New York Cityâs One World Trade Center became the tallest building in the Western Hemisphere, at 1,776 feet.
