大自然的蓝色奇观 Nature's blue wonder

斯太尔河，奥地利

今天这张照片并未经过调色，奥地利斯太尔河的水真的就是这般湛蓝。斯太尔河流经托特斯山脉，当地植被稀少，那为什么斯太尔河还能如此清澈湛蓝？答案就在环绕斯太尔河谷的群山之中。雨水和融化的雪水流入斯太尔河后，其中较重的沉积物沉到水底，而较细的沉积物则会悬浮在水中。被沉积物散射或反射的阳光就赋予了河水这样鲜艳的蓝色。

Steyr River, Austria

These whitewater rapids are found in Upper Austria, where the Steyr River crashes down from the barren Totes Gebirge (the Dead Mountains) through this verdant landscape. When it comes to the ancient town of Steyr, at the foot of the Alps, it will meet the Enns River, which flows into the Danube.

What gives the Steyr that stunning blue hue? The answer is found in the mountains themselves. When there's rainfall or the surrounding snow melts, eroded sediment flows into the river. Heavier sediment sinks to the bottom and finer sediment stays suspended in the water. Sunlight is scattered or reflected by the sediment, allowing us to see a vibrant shade of blue, as the Steyr crashes through this lush landscape.

奥拉河，图尔库，芬兰

图尔库大教堂矗立在奥拉河口附近的霜冻森林之上。这座大教堂最初是在13世纪晚期用木头建造的，并在14世纪和15世纪使用石头作为主要建筑材料进行了扩建。事实证明这是明智的选择，因为1827年的图尔库大火灾吞噬了这座城市的大部分地区，也对大教堂造成严重损坏。数年后，这座教堂再次迎来了重建。

Aura River in Turku, Finland

The Turku Cathedral rises above the frosted forests near the mouth of the Aura River, which runs through the middle of Turku, Finland.

Originally built out of wood in the late 13th century, the cathedral was expanded in the 14th and 15th centuries, mainly using stone as construction material. This would prove wise, as the Great Fire of Turku consumed much of the city in 1827 and badly damaged the cathedral. It was rebuilt over the next few years.

历经百年的锡安国家公园 103 years of Zion

锡安国家公园的维珍河

我们的照片将我们带到16英里长的维珍河，在那里它穿过犹他州锡安峡谷上游，形成了一个壮观的千英尺深的峡谷。流经锡安国家公园（今天已满103岁！），由于科罗拉多高原、大盆地和莫哈韦沙漠交汇处的独特生物群落，维珍河是其他地方所没有的独特植物和动物的家园。如果没有维珍河水系的水，像世界上最稀有的物种之一的wondfin小鱼这样的生物就不可能存在。

Virgin River in Zion National Park

Our photo brings us to a 16-mile stretch of the Virgin River where it cuts a spectacular thousand-foot-deep gorge through the upper reaches of Utah's Zion Canyon. Flowing through Zion National Park (which turns 103 today!), the Virgin River is home to unique plants and animals that aren't found anywhere else, due to the unique intersection of biomes found where the Colorado Plateau, Great Basin, and Mojave Desert all meet. Without the water of the Virgin River system, creatures like the woundfin minnow, one of rarest species on the planet, couldn't exist.

从大酒钵里喝一口 Take a sip from the Punchbowl

苏格兰阿伯丁郡的奎奇河

在苏格兰东部高地，一条小而受人喜爱的河流蜿蜒在凯恩戈姆山脉的森林高原上，流经一条峡谷。奎伊奇河是自然爱好者、徒步旅行者和勇敢的划桨者经常光顾的地方，他们愿意勇敢地面对它惊人的湍急水流和几处瀑布，其中就包括这里的奎伊奇林。这些瀑布以你在图片左侧看到的岩石中的碗状空洞而闻名。

这一被称为“Punch Bowl”的自然景观已成为那些游览河流并沿着河岸徒步3英里的游客的明星景点。据传说，拥有这些森林的18世纪贵族马尔伯爵会在洞顶上放一个仪式用的冲头碗，在成功猎鹿后从中喝水。英国在位时间最长的君主维多利亚女王也经常光顾这些松林，并在瀑布附近建了一座现已废弃的小屋。虽然奎奇河的美丽适合女王，但你不必成为皇室成员就可以享受它。

River Quoich in Aberdeenshire, Scotland

In the eastern Highlands of Scotland, tucked into the forested plateaus of the Cairngorms mountain range is a small but beloved river that runs through a ravine. The River Quoich is frequented by nature lovers, hikers, and intrepid paddlers willing to brave its surprisingly swift currents and its several waterfalls, including the one featured here, the Linn of Quoich. These falls are famous for the bowl-shaped cavity in the rock that you see on the left side of this image.

Called the Punch Bowl, this natural feature has become the star attraction for those who visit the river and take the 3-mile hike along its banks. According to lore, the Earl of Mar, the 18th-century nobleman who owned these woods, would place a ceremonial punch bowl atop the hole and drank from it after a successful deer hunt. Queen Victoria, Britain's longest-reigning monarch, also frequented these pine woods and built a now derelict lodge near the falls. While the beauty of the River Quoich is fit for a queen, you don't have to be royalty to enjoy it.

令人印象深刻的时刻 Time to make an impression

Caribou rutting season in Alaska

It's that time of year when Alaskan caribou are beginning to feel a little frisky. From late September until early November, males will be strutting their stuff, locking antlers with one another, and competing for the attention of females in hopes of furthering the species. Successful males will mate with 15-20 females a season. After the rutting season males will shed their antlers while females keep theirs until spring. In today's photo we're looking at some caribou in southcentral Alaska crossing the Susitna River.

Alaska has 32 distinct caribou herds. It's likely today's caribou are members of the Nelchina herd, which roams across about 20,000 square miles in the high basin surrounded by the Talkeetna, Chugach, Wrangell, and Alaska ranges. The Nelchina herd is among the most studied and recognized of Alaskan caribou partly because their range is relatively close to the major human population centers of the state. The herd has provided food for Alaskans for hundreds of years and its population is maintained through carefully monitored hunting regulations. But caribou populations can fluctuate from one year to the next depending on the availability of food and severity of the weather.

阿拉斯加驯鹿发情季节

每年的这个时候，阿拉斯加驯鹿开始感到有点活泼。从9月下旬到11月初，雄性将昂首阔步，相互锁住鹿角，争夺雌性的注意力，以期进一步丰富物种。成功的雄性每季度将与15-20只雌性交配。发情期过后，雄性会脱掉鹿角，而雌性会一直保留到春天。在今天的照片中，我们看到一些驯鹿在阿拉斯加中南部穿越苏西特纳河。

阿拉斯加有32个不同的驯鹿群。今天的北美驯鹿很可能是Nelchina鹿群的成员，它们在塔基特纳山脉、楚加赫山脉、朗格尔山脉和阿拉斯加山脉环绕的高盆地中漫游，占地约20000平方英里。Nelchina驯鹿群是阿拉斯加驯鹿中研究和认识最多的驯鹿群之一，部分原因是它们的分布范围相对接近该州的主要人口中心。数百年来，牧群一直为阿拉斯加人提供食物，通过仔细监测狩猎法规来维持种群数量。但是驯鹿的数量可能会随着食物的供应和天气的恶劣程度而在一年到另一年之间波动。

匆匆而逝的河流 The rivers run through us

World Rivers Day

On World Rivers Day, we honor what may be thought of as the queen of them all—the Amazon, which flows more than 4,000 miles mostly through the South American countries of Peru and Brazil. The Amazon discharges a whopping 58 million gallons of fresh water into the ocean every second, enough to fill 83 Olympic-sized swimming pools, far more water than any other river in the world. It accounts for 20% of all fresh water that flows into the world's seas and oceans. It's also the vital heart of the largest and most diverse rain forest in the world—the Amazon Rain Forest is home to a third of the world's animal species and its trees and plants pull billions of tons of heat-trapping carbon dioxide from the atmosphere each year, making it one of the Earth's best defenses against climate change.

Mark Angelo, a river conservationist from British Columbia, launched World Rivers Day in 2005 to recognize the importance of rivers to the survival of humanity and millions of species all over the world. Rivers are our best source of fresh water, they can be an important energy source, they're the foundations of complex ecosystems, and provide crucial sources of irrigation for our crops, among other contributions to our way of life. Besides, who doesn't love a float down a lazy river?

世界河流日

在世界河流日，我们向可能被认为是所有河流中的女王的亚马逊河致敬，该河流经4000多英里，主要流经南美国家秘鲁和巴西。亚马逊河每秒向海洋排放5800万加仑的淡水，足以填满83个奥运会规模的游泳池，远远超过世界上任何其他河流。它占流入世界海洋的所有淡水的20%。亚马逊雨林是世界上最大、种类最多的雨林的重要心脏，是世界三分之一动物物种的家园，其树木和植物每年从大气中吸收数十亿吨的吸热二氧化碳，使其成为地球抵御气候变化的最佳防御措施之一。

来自不列颠哥伦比亚省的河流保护主义者马克·安吉洛（Mark Angelo）于2005年发起了世界河流日活动，以认识到河流对全世界人类和数百万物种生存的重要性。河流是我们最好的淡水来源，它们可以是重要的能源，是复杂生态系统的基础，为我们的作物提供重要的灌溉资源，以及对我们生活方式的其他贡献。此外，谁不喜欢沿着懒惰的河流漂流？

In Texas, even the riverbend is big

We're celebrating the 77th birthday of Big Bend National Park, the place the National Park Service calls 'one of the last remaining wild corners of the United States.' To get here, you have to be committed. This rugged terrain, which covers almost a million acres, is one of the most remote spots in the country—it's hours from the nearest towns or the closest airport, making it one of the least-visited national parks in the country. Those who do make the effort to get to Big Bend are rewarded with an undeveloped natural beauty, and silence, two things that seem to be in short supply these days.

At Big Bend you'll find craggy hiking trails, red mountain vistas, limestone canyons, and hot springs alongside the famous Rio Grande. There's also the wildlife you'd expect to find in the Wild, Wild West, including rattlesnakes, packs of javelinas, and 20 species of bats. But it's the huge night sky unencumbered by light pollution that draws stargazers to Big Bend from all over the world. After all, everything, as they say, is bigger in Texas.

在德克萨斯州，连河湾都很大

我们正在庆祝大弯国家公园77岁生日，国家公园管理局称之为“美国仅存的野生角落之一”。要到这里，你必须全力以赴。这片崎岖不平的土地占地近百万英亩，是美国最偏远的地区之一，距离最近的城镇或最近的机场只有几个小时的路程，使它成为美国游客最少的国家公园之一。那些努力到达大弯的人得到的回报是未开发的自然美景和沉默，这两样东西现在似乎供不应求。

在大弯，你会发现崎岖的徒步小径、红色的山景、石灰岩峡谷和著名的格兰德河旁的温泉。在野生的西部，你也会发现野生动物，包括响尾蛇，标枪和20种蝙蝠。但正是没有光污染的巨大夜空吸引着来自世界各地的天文爱好者来到大弯。毕竟，正如他们所说，德克萨斯的一切都更大。

Get on your bike and ride

In honor of the UN's World Bicycle Day, we're at Triglav National Park in Slovenia, with a birds-eye view of riders crossing this dubious-looking wooden suspension bridge over the glacial blue water of the river called Soča. Protecting some of the most magnificent mountain landscapes of the Julian Alps, Triglav is the country's only national park, but it's a stunner. Running along Slovenia's northwestern border with Italy, Triglav was first protected as a 'conservation park' in 1924, then made a national park in 1981. The park gets its name from the mountain at its heart, Triglav, long considered a symbol of Slovenia and of Slovene identity.

Since 2018, the UN General Assembly has recognized June 3 as World Bicycle Day to honor 'the uniqueness, longevity, and versatility of the bicycle, which has been in use for two centuries.' The bicycle has gone through many iterations since Karl Drais created the brake-less, pedal-less bike forerunner called a 'velocipede' in 1817. The German inventor would likely be floored by today's variety of bike options, from new lightweight road bikes to heavier mountain bikes with fatter, knobby tires designed to handle rougher terrain. More than 200 years after von Drais introduced his two-wheeled contraption, bicycles remain as popular as ever. Chances are there's one just waiting for you to take it for a spin, and what better day to do so than World Bicycle Day?

骑上你的自行车

为了纪念联合国的世界自行车日，我们来到了斯洛文尼亚的特里格拉夫国家公园，鸟瞰着骑手们穿过这座看起来可疑的木制吊桥，桥上是一条蓝色的冰川河，这条河被称为Soča。特里格拉夫保护着朱利安阿尔卑斯山上一些最壮丽的山景，是这个国家唯一的国家公园，但它是一个惊人的奇迹。特里格拉夫位于斯洛文尼亚西北部与意大利交界处，1924年首次作为“保护公园”受到保护，1981年被列为国家公园。该公园的名字来源于其核心山脉特里格拉夫，长期以来被认为是斯洛文尼亚和斯洛文尼亚人身份的象征。

自2018年以来，联合国大会将6月3日定为世界自行车日，以纪念自行车的独特性、长寿性和多功能性，这种自行车已经使用了两个世纪。自从卡尔·德赖斯发明了无刹车自行车以来，自行车经历了多次迭代，1817年被称为“velocipede”的无踏板自行车的先驱。这位德国发明家很可能会被今天各种各样的自行车选择所打倒，从新的轻型公路自行车到更重的山地自行车，这些自行车的轮胎设计得更胖、多节，以适应更崎岖的地形。在冯·德赖斯发明了他的双轮装置200多年后，自行车仍然像以前一样流行。很有可能有一天你正等着去兜风呢，还有什么日子比世界自行车日更好呢？

A visit to Limerick on Limerick

Today is Limerick Day, and what better place to celebrate this unofficial holiday than in Limerick, Ireland. The connection between the historic city and the humorous, five-line verse is unclear. Several theories have been purported, none of them definitive. But the city of Limerick has embraced its namesake poetry style and in recent years the Limerick Writers' Centre has hosted an annual competition called Bring Your Limericks to Limerick.

We're looking across the River Shannon at the historic part of the city, a medieval section once walled off by the Vikings around 812 and known today as King's Island. That's King John's Castle on the left, built on the order of King John in 1200. Over on the right is St. Mary's Cathedral, which dates from 1168 and is the oldest building in Limerick still in use. History suggests the area was settled long before the Vikings conquered it and set about destroying Irish public records. The earliest map of Ireland, produced in 150 CE by historian and overall polymath Ptolemy, shows a place called 'Regia' at the same site as King's Island.

利默里克之旅

今天是利默里克日，还有什么比在爱尔兰利默里克更好的地方来庆祝这个非官方节日呢。这座历史名城与幽默的五行诗之间的联系尚不清楚。有几个理论被提出，没有一个是确定的。但利默里克市已经接受了同名的诗歌风格，近年来，利默里克作家中心举办了一个名为“把你的利默里克带到利默里克”的年度比赛。

我们在香农河对岸眺望这座城市的历史部分，这是一个中世纪的部分，812年左右曾被维京人围住，今天被称为国王岛。左边是约翰国王的城堡，1200年按照约翰国王的命令建造。右边是圣玛丽大教堂，建于1168年，是利默里克至今仍在使用的最古老的建筑。历史表明，早在维京人征服该地区并着手销毁爱尔兰公共记录之前，该地区就已定居。最早的爱尔兰地图是由历史学家兼托勒密全才于公元150年绘制的，图中显示了一个与国王岛位于同一地点的名为“里加”的地方。
