Zion National Park, Utah

Today, we're celebrating the 102nd anniversary of Southwest Utah's Zion National Park with a visit to its Subway slot canyon. Zion is defined by its breathtakingly steep red cliffs, its maze of sandstone canyons, and its waterfalls with colorful hanging gardens. Visitors here can trek for miles, ducking into crevices and resting in canyons once occupied by the Ancestral Puebloans.

The bravest souls might venture into Zion's Subway. Yes, there's a 'subway' here, but it's not a transit system nor a sandwich shop. You see the image we are featuring today? That's the Subway. It's a geologic marvel, a hollowed-out canyon reminiscent of a subway tunnel. To get here requires some technical experience, or at least a guide. There will be bouldering, climbing down waterfalls, possibly rappelling, and a 9-mile roundtrip hike on a trail which is a running stream with parts so deep, hikers have to wade or swim, depending on water levels. Did we mention the water is cold? But all that work will be worth it in the end for a photo like this. Zion is the third most-visited national park in the country, but the park grants just 60 permits a day to hikers who want to attempt a visit to the Subway.

犹他州锡安国家公园

今天，我们将参观犹他州西南部的锡安国家公园的地铁狭缝峡谷，以庆祝其102周年。锡安以其惊人的陡峭红色悬崖、迷宫般的砂岩峡谷和瀑布以及五颜六色的空中花园而著称。这里的游客可以跋涉数英里，潜入裂缝，在曾经被祖先普韦布洛人占据的峡谷中休息。

最勇敢的人可能会冒险进入锡安的地铁。是的，这里有“地铁”，但它既不是公交系统，也不是三明治店。你看到我们今天展示的图像了吗？那是地铁。这是一个地质奇迹，一个空洞的峡谷让人想起地铁隧道。到这里需要一些技术经验，或者至少需要一个向导。这里将有抱石、爬下瀑布、可能是攀岩，还有9英里的往返徒步旅行。这条小道是一条流动的溪流，局部很深，徒步旅行者必须涉水或游泳，具体取决于水位。我们有没有提到水是凉的？但对于这样一张照片来说，所有这些工作最终都是值得的。锡安是该国第三大游客最多的国家公园，但该公园每天只向想要尝试参观地铁的徒步旅行者发放60张许可证。
