洋溢着社区氛围 Overflowing with community

奥洛乌佩纳瀑布, 莫洛凯岛, 夏威夷

莫洛凯岛常被称为“最具夏威夷气息岛屿”，这里的节奏缓慢而从容，由自然环境与紧密相连的社区共同塑造。岛屿形成于一百多万年前的火山活动，占地约260平方英里，从太平洋中隆起，延展出修长的山脊与开阔的谷地。与喧闹的邻岛不同，莫洛凯岛拒绝大规模开发，保留了强烈的在地凝聚力，家庭、传统以及对土地的守护构成了这里的核心价值。人们的生活围绕着海洋、土地，以及代代相传的故事展开。

今天的画面中，奥洛乌佩纳瀑布矗立在岛屿北岸之上，从陡峭的海崖倾泻而下，落差达2953英尺。水源来自季节性降雨，水流常常散落成细密的银色水帘。环绕其间的海蚀峭壁高耸入云，跻身世界最高之列，只能通过直升机或船只抵达，为这片景观更添幽秘氛围。

如今，行走在莫洛凯岛宁静的道路上，面对空旷的海滩与亲密的社区，人们仿佛回到从前的夏威夷：安静而真诚，生活与土地紧紧相依。

Olo'upena Falls, island of Moloka'i, Hawaii

Moloka'i, often called the most Hawaiian of the islands, offers a slower rhythm shaped by nature and strong community ties. Formed by volcanic activity more than a million years ago, the island covers about 260 square miles and rises from the Pacific Ocean in long ridges and broad valleys. Unlike its busier neighbors, Moloka'i has resisted large-scale development, preserving a strong sense of local cohesion where families, traditions, and stewardship of the land encapsulate central values. Life here focuses on the ocean, the land, and stories passed down through generations.

Seen in today's image, Olo'upena Falls towers above the island's north shore. Dropping 2,953 feet down steep sea cliffs, the falls are fed by seasonal rains and often fan into delicate silver streams. The surrounding sea cliffs, among the highest on Earth, are accessible only by helicopter or boat, adding to their mystique.

Today, Moloka'i's quiet roads, uncrowded beaches, and close-knit community offer a rare chance to experience Hawaii as it once was—peaceful, welcoming, and deeply connected to the land.

一幅壮丽的景象 One grand view

大峡谷国家公园周年纪念

大峡谷国家公园每天都有新的故事，但2月26日这一天格外特别，纪念的是1919年大峡谷正式成为国家公园的历史时刻。这一里程碑式的决定，守护了美国最具代表性的自然奇观。峡谷深处，科罗拉多河缓缓流淌，穿行于层叠的岩石之间，跨越数百英里，以季节为节拍，静静雕刻着峡谷的生命。

对来到这里的游客而言，这个周年纪念是一次放慢节奏、重新发现峡谷的好机会。护林员主持的讲解与活动，带人走进峡谷的地质、野生动物与人文历史。南缘步道上，视野豁然开朗，加州神鹰在头顶滑翔，麋鹿、黑尾鹿和大角羊自在游走于不同生态环境之中。夜晚仰望星空，或驻足观景台，冬季清朗的夜色让一切更显深邃。

Grand Canyon National Park anniversary

Every day at Grand Canyon National Park tells a story, but February 26 is a special one. It marks the Grand Canyon's designation as a national park in 1919, a milestone that helped protect one of the most iconic natural wonders in the United States. At the heart of it all flows the Colorado River, winding for hundreds of miles through layered stone, quietly shaping the canyon one season at a time.

For visitors in the area, the anniversary is a perfect chance to slow down and explore. Ranger-led programs and talks highlight the canyon's geology, wildlife, and cultural history. A walk along the South Rim offers sweeping views where California condors circle overhead, while elk, mule deer, and bighorn sheep roam the park's diverse habitats. Stargazing and scenic overlooks add to the experience, especially during winter's clearer nights.

You don't need to be nearby to take part. The National Park Service provides live webcams from viewpoints across the park, sharing real-time sunrises, weather shifts, and daily rhythms. Whether in Arizona or far away, February 26 is an open invitation to connect with the Grand Canyon in your own way.

门登霍尔冰川的冰洞，阿拉斯加州，美国 Ice cave in the Mendenhall Glacier, Alaska, USA (© Designpics/Adobe Stock)

冰，由内而外透出光芒 Ice, lit from within

门登霍尔冰川，阿拉斯加

阿拉斯加朱诺城外，门登霍尔冰川静静隐匿其间，内外皆仿佛幻境。走入罕见的蓝色冰洞，世界骤然安静，光线透过历经数百年压实的冰层，映照四周。冰川自朱诺冰原绵延约十三英里，缓缓流向下方山谷，在年复一年的流动中悄然改变形态。

湛蓝的色泽源于高密度冰体对光线的吸收，其他波段被吞没，只留下蓝色。冰洞转瞬即逝，融水不断雕刻出通道，随着冰川消退与坍塌，光影也随之消散。

如今，进入冰洞已变得越来越罕见，且难以预测，但这条冰川依然是科学研究的重点。冰川在过去一个多世纪里被研究、被凝视、被敬畏，如今不断退却，为科学家们提供了一份清晰可见的环境变化记录。在这些泛着光芒的冰洞内，壮丽与脆弱并存，时刻提醒着人们：阿拉斯加的冰封景观，始终在变动之中，且稍纵即逝。

Mendenhall Glacier, Alaska

Hidden just outside Juneau, Alaska, the Mendenhall Glacier feels almost unreal, inside and out. Step into one of its rare blue ice caves, and the world turns quiet and luminous, with light filtering through centuries-old compacted ice. The glacier stretches about 13 miles from the Juneau Icefield, slowly flowing toward the valley below and reshaping itself year by year.

Its striking blue color comes from the ice's density, which absorbs most wavelengths of light and leaves behind vivid shades of blue. These caves are fleeting by nature, forming as meltwater carves tunnels through the glacier and disappearing, or collapsing entirely, as conditions shift.

While reaching the caves has become increasingly rare and unpredictable, the glacier remains closely studied and deeply admired. Over the past century, it has retreated dramatically, offering scientists a visible record of environmental change. Inside these glowing chambers, beauty and fragility meet, creating a powerful reminder of how dynamic and temporary Alaska's frozen landscapes truly are.

群山的母亲 The mother of hills

马姆托尔，德比郡，英格兰

“颤抖的山”这个绰号听起来颇具戏剧性，但对马姆托尔来说，却是数百年来的真实写照。它耸立在英格兰峰区国家公园的卡斯尔顿上方，这里也是英国首个国家公园，占地约555平方英里。这座地标的名字源自古英语，“mam”意为“母亲”，暗指它仿佛怀抱着周围起伏的小丘。然而，这座“母亲之山”却以不稳定而闻名：页岩与砂岩层层叠加，使山体长期滑动，1979年的一次坍塌甚至导致A625公路永久关闭。

在工程技术介入之前，这座“不稳定”的山早已有了人类的足迹。约3500年前，青铜时代的人们在马姆托山顶筑起宏大的山堡。至今，山脊上仍清晰可见圆形居所与古老道路的遗迹，静静诉说着这里长期作为重要聚落的历史。

从地质角度看，这座海拔约1696英尺的山峰，清晰呈现了峰区动荡不安的地质历史。峭壁间裸露的岩层，形成于3.2亿多年前的热带海洋环境；而附近的洞穴，如著名的蓝约翰洞穴，则孕育着世界上极为罕见的矿物。如今，马姆托尔依然是公园内最具代表性的徒步路线之一，沿着山脊行走，既能感受原始野性，又能行走得轻松自在。

Mam Tor, Derbyshire, England

'Shivering Mountain' is a dramatic nickname, but Mam Tor has earned it over hundreds of years. Rising above Castleton in England's Peak District, it lies within the United Kingdom's first national park, which spans 555 square miles. This landmark takes its name from Old English, 'mam' meaning 'mother,' a nod to the smaller hills it appears to cradle. Yet this 'mother mountain' is famously unstable. Its layers of shale and sandstone have caused landslips for centuries, including a collapse that permanently closed the A625 road in 1979.

Long before modern engineers battled its shifting slopes, Bronze Age people built a large hillfort on Mam Tor's summit around 3,500 years ago. The ridge still shows traces of a settlement, with roundhouses and ancient trackways that reveal its long‑standing importance.

Geologically, this 1,696‑foot peak showcases the Peak District's turbulent past. Its cliffs reveal layers formed in tropical seas over 320 million years ago, while nearby caverns—such as Blue John Cavern—hold minerals found in very few places on Earth. Today, Mam Tor remains one of the park's most iconic walks, offering a ridge path that feels both wild and wonderfully accessible.

光照之处 Where light falls

约塞米蒂国家公园里的火瀑布，加利福尼亚州

今天，是安塞尔·亚当斯的诞辰。正是他的镜头，塑造了世人心中优胜美地的形象。这座国家公园以雄伟的花岗岩岩壁、壮观的瀑布和变幻莫测的光线闻名，持续激发着一代又一代艺术家的创作灵感。而其中最令人着迷的景象，是被称作“火瀑”的奇观。这一名称，其实源自优胜美地历史中的两种不同景象。在过去，人们曾聚集在冰川点，观看一种人工制造的奇观：炽热的余烬被推下悬崖，在夜幕中倾泻而下，宛如一条燃烧的火流。

相比之下，真正令人着迷的，是埃尔卡皮坦山马尾瀑布上出现的自然火瀑。在二月中下旬的少数几个黄昏，落日以恰到好处的角度照亮瀑布，使水流染上一层炽亮的橙色，仿佛熔岩顺着山体缓缓倾泻。这一奇观并非年年可见，它依赖于晴朗的天空、充沛的水量，以及分秒不差的时机。1973年，摄影师盖伦·罗威尔首次捕捉到这一罕见瞬间，并拍下广为流传的影像，让这一天然奇观走入公众视野，成为优胜美地最令人惊叹的景象之一。

Horsetail Fall in Yosemite National Park, California

Today we celebrate the birthday of Ansel Adams, a photographer whose vision helped shape the world's perception of Yosemite National Park. Yosemite is renowned for its granite walls, dramatic waterfalls, and striking light, all of which have inspired generations of artists. One of its most intriguing sights is the Firefall, a term that refers to two distinct events in the park's history. For decades, visitors gathered at Glacier Point to watch an artificial Firefall, in which embers were pushed off the cliff in a glowing stream of fire.

Far more mysterious is the natural Firefall at Horsetail Fall on El Capitan. On a few evenings in mid- to late February, the sunset hits the waterfall at just the right angle, turning it bright orange, as if molten lava were sliding down the mountain. Clear skies, sufficient water, and perfect timing are all essential for this effect to occur. In 1973, Galen Rowell observed this rare phenomenon and took the first widely known photograph of the natural Firefall—bringing widespread attention to one of Yosemite's most remarkable sights.

大地凝视着我们 Where the land stares back

龙之眼，挪威乌塔克莱夫海滩

“龙之眼”这个名字听起来像是出自传说，而当你站在挪威罗弗敦群岛的乌塔克莱夫海滩上时，你很容易就能明白为什么它会得此美名。这处地貌由古老的岩石雕琢而成，四周环绕着沙滩和大海，看起来栩栩如生，仿佛大地本身正在注视着你。它历经数千年的冰雪和海水的侵蚀塑造而成，如今已成为该地区最迷人的景点之一。

尽管龙眼有着神话般的名字，但它实际上是一个冰川坑洞。大约 2 万年前，汹涌的融水从广阔的芬诺斯坎迪亚冰原下流过，在变质岩中形成了一个圆形凹洞。在强大的压力下，携带着沙石的水流冲刷着基岩，逐渐侵蚀出壁面光滑的洼地。大约 1.6 万年前，冰雪退去，这些地貌显露出来，留下了像龙眼这样的地貌，龙眼的中心镶嵌着一块巨石或 “瞳孔”。

如今，“眼睛 ”继续随着各种元素的变化而变化。根据潮汐的变化，海浪会淹没空洞或将其剥离，而藻类和光线则不断重塑其表现形式，模糊了传说与景观之间的界限。

Dragon's Eye, Uttakleiv Beach, Norway

Dragon's Eye sounds like something pulled from legend, and standing on Norway's Uttakleiv Beach in the Lofoten Islands, it's easy to see why. The formation, carved into ancient rock and framed by sand and sea, looks uncannily alive, as though the land itself is watching you. Shaped over thousands of years by ice and water, it has become one of the region's most captivating sights.

Despite its mythic name, the Dragon's Eye is actually a glacial pothole. It is a circular hollow sculpted into metamorphic rocks by turbulent meltwater flowing beneath the vast Fennoscandian Ice Sheet around 20,000 years ago. Under intense pressure, water carrying sand and stones ground into the bedrock, gradually eroding smooth-walled depressions. When the ice retreated roughly 16,000 years ago, these features were revealed, leaving behind formations like the Dragon's Eye, complete with a boulder—or 'pupil'—settled at its center.

Today, the Eye continues to shift with the elements. Depending on the tide, waves flood the hollow or strip it bare, while algae and light constantly reshape its expression, blurring the line between legend and landscape.

福气满满，马年大吉 Wishing you a prosperous Year of the Horse

马年春节

过年好！今天是中国民间最隆重最富有特色的传统节日之一。其实每年从腊八或小年开始，到元宵节，都称之为过年。春节期间，中国全国各地人们都举办着感恩祈福、阖家团聚、除旧布新、迎禧接福、祈求丰年为主要内容的活动。而中国农历新年也在世界各地掀起了“中国风”，春节庆祝活动内容丰富多彩，具有重要的历史、艺术和文化价值。

马在中国文化中象征着力量、速度、活力与进取精神。自古以来，马在战争、农业和商业中都扮演着重要角色，在文学、成语和俗语中也占有一席之地，如“马到成功”和“马上封侯”常用于表达顺利与成功。马的形象被历代文人歌颂，并在艺术和文化创作中频繁出现。

Chinese New Year

Chinese New Year, also known as the Spring Festival, marks the beginning of a new year on the traditional Chinese lunisolar calendar. This calendar follows the phases of the moon and the rhythms of the seasons. Red lanterns—like the ones shown in today's image—are widely associated with the celebration. The holiday falls on the new moon between January 21 and February 20 and has been observed for more than 2,000 years. In 2024, UNESCO added the Spring Festival to its Intangible Cultural Heritage of Humanity list, recognizing its cultural and historical importance.

The festival follows a 15-day sequence, beginning on Chinese New Year's Eve and ending with the Lantern Festival. Each day traditionally carries its own customs, though practices vary from region to region. Even with these regional differences, the overall progression of the celebration remains similar across communities, reflecting a shared cultural framework tied to the lunar calendar.

The date of Chinese New Year changes annually because it is based on lunar cycles rather than the Gregorian calendar. This shifting date sets it apart from fixed-date holidays and explains why the festival's timing varies each year, even though its internal structure stays consistent.

祝除夕团圆，新年顺遂！ Wishing you all the best in the New Year!

中国的除夕夜

除夕夜，街头的龙形灯笼正蜿蜒舒展，金鳞流转间仿佛蓄着时光的温度；而远处隐约响起的蹄声，恰似春风捎来骏马的问候——这是龙与马的相逢，是古老祥瑞与崭新朝气在岁月门楣的相会。

这座龙灯以腾跃之姿盘绕成家门前的守护，又以马踏青云的昂扬，将锦绣前程写入每扇温暖的窗棂。新的一年将至，让我们将龙马精神融入血脉，每一步都是光芒蜿蜒处，每一程皆有长风万里随。

世界鲸鱼日

世界鲸鱼日定于每年2月的第3个星期日，起源于20世纪80年代的夏威夷。当时，当地社区会庆祝座头鲸在迁徙季节重返近海。这一纪念日随后逐渐受到国际关注，尤其是在1986年国际捕鲸委员会通过商业捕鲸禁令之后，该举措成为全球鲸类保护的重要里程碑。

座头鲸修长的胸鳍格外醒目，而它们在繁殖季发出的复杂歌声，更为海洋增添了神秘回响。座头鲸的迁徙路线高度规律，常年沿岸而行，不仅成为季节更替的自然标志，也使其成为最早被关注和保护的鲸类之一。

鲸类保护不仅是禁捕，更关乎整个海洋环境。渔业、航运、噪音、塑料污染与海温变化，共同影响鲸的迁徙路径和觅食节奏。在蒙特雷湾，座头鲸的觅食依托于健康丰富的生态系统。猎物反哺海洋，营养滋养浮游生物，生命由此串联成完整的食物网。世界鲸鱼日，关注鲸鱼，也是关注海洋的未来。

World Whale Day

World Whale Day, observed on the third Sunday of February, began in the 1980s in Hawaii, where communities celebrated the seasonal return of migrating humpback whales. The day gained wider recognition after the International Whaling Commission's 1986 moratorium on commercial whaling, which marked a major milestone in international whale conservation.

Humpback whales are easily recognizable by their long pectoral fins and are known for their complex songs associated with breeding behavior. Their predictable migrations bring them close to shore, turning them into both a cultural marker of the season and a focal point for early conservation efforts.

Today, whale conservation extends far beyond hunting restrictions and includes how we use and manage the oceans more broadly. Fishing activity, major shipping routes, underwater noise, plastic waste, and rising ocean temperatures all influence whale movement and feeding patterns. Pictured here are humpback whales feeding cooperatively in Monterey Bay—a behavior that depends on healthy ecosystems and reliable prey availability. Whales also contribute to ocean systems by circulating nutrients that support plankton growth and marine food webs. World Whale Day highlights the ongoing importance of thoughtful ocean stewardship in maintaining balanced marine ecosystems.

连接老挝和泰国的第三座泰老友谊大桥 (© chaiyut samsuk/Getty Images)

为拉近距离而建 Built to bring closer

连接老挝和泰国的第三座泰老友谊大桥

在没有桥梁的年代，河流决定人们能走多远；而随着桥梁的建立，节奏掌握开始在人的手中。这种转变正是跨境基础设施的重要意义所在，比如连接老挝与泰国的第三座大桥泰老友谊大桥。桥梁结构多样，各有针对性：拱桥应对压力，悬索桥跨越长距离，混凝土箱梁桥则追求稳定与高效承载。这座桥选择箱梁设计，正是为应对湄公河宽阔水面与快速水流的现实需求。

2011年启用的第三座泰老友谊大桥旨在加强泰国那空帕农府与老挝甘蒙省他曲之间的交通联系。该项目由泰国出资建设，延续了此前连接廊开与万象、穆达汉与沙湾拿吉的跨境桥梁体系。全长4669英尺，双向两车道，既服务本地通勤，也承担长途货运任务，有效缓解交通拥堵，提升跨境通行的稳定性和可靠性，并进一步推动区域物流、旅游和跨境合作，重塑区域联系。

Third Thai-Lao Friendship Bridge connecting Laos and Thailand

Before bridges, rivers set the pace of travel. Now, with bridges, people do. That shift explains why cross-border links like the Third Thai-Lao Friendship Bridge connecting Laos and Thailand matter. Bridges come in many forms, each built to meet a specific challenge. Arch bridges manage compression, suspension bridges span long distances, and concrete box-girder bridges prioritize stability and load efficiency. This bridge uses the box-girder design, making it a practical choice for crossing the wide, fast-moving Mekong River.

Opened in 2011, the Third Thai-Lao Friendship Bridge was developed to strengthen transport links between Nakhon Phanom Province in Thailand and Thakhek, in Khammouane Province, Laos. Thailand funded much of the project, continuing a pattern set by earlier crossings such as the First Thai-Lao Friendship Bridge between Nong Khai and Vientiane and the Second Thai-Lao Friendship Bridge linking Mukdahan and Savannakhet.

Measuring about 4,669 feet, the bridge comprises two traffic lanes, serving local commuters and long-haul freight alike. This has helped ease congestion at other crossings and made cross-border movement more reliable. Beyond transport efficiency, the bridge supports logistics, tourism, and cross-border cooperation, showing how infrastructure can quietly reshape regional connections without demanding attention.
