岁月雕琢，风景始成 Aged to scenic perfection

大烟山国家公园迎来了92周年生日！

这些山随着时间慢慢形成——1934年6月15日，它们得到了保护。这一天，大烟山国家公园在田纳西州和北卡罗来纳州成立。公园面积超过522,000英亩，名字来源于漂浮在山脊上的天然烟雾。作为阿巴拉契亚山脉的一部分，这些山峰已有超过三亿年的历史。

美洲原住民在这些山里狩猎已有大约14,000年。考古学家在动物迁徙路线沿线发现了古旧时代的投射点，而林地时期的遗址则展示了约2,000年前的陶器和早期农业实践。

公园被称为“世界蝾螈之都”，是一个生物多样性热点，栖息着大约30种蝾螈、黑熊、麋鹿、200多种鸟类以及成千上万种植物。这里的森林随海拔高度变化，支持着多样的生态系统。Kuwohi是最高点，可以欣赏到开阔的景色。同时，Cades Cove和Cataloochee Valley保存了反映公园建立前当地生活的建筑。

Great Smoky Mountains National Park turns 92!

These mountains were shaped over time—and June 15, 1934, helped protect them. That's when the Great Smoky Mountains National Park was established in Tennessee and North Carolina. Covering over 522,000 acres, the park takes its name from the natural smoky haze drifting over its ridgelines. Part of the Appalachian Mountains, these peaks are over 300 million years old.

Native Americans have hunted in these mountains for around 14,000 years. Archaeologists have found Archaic-period projectile points along animal migration routes, while Woodland-period sites reveal 2,000-year-old ceramics and early farming practices.

Recognized as the Salamander Capital of the World, the park is a biodiversity hotspot, home to around 30 salamander species, black bears, elk, over 200 bird species, and thousands of plant varieties. Its forests shift with elevation, supporting a wide range of ecosystems. Kuwohi is the highest point, offering sweeping views. Meanwhile, Cades Cove and Cataloochee Valley contain preserved buildings that reflect life in the region before the park's creation.

岁月的层峦 Layers of change

南达科他州恶地国家公园的落日

层叠的嵴线横跨南达科他州的恶地国家公园。随着光影变幻，饱受侵蚀的山峰与沟谷悉数呈现在眼前，其间交织着粉红、灰白与金黄的岩层条带。时至今日，风力和流水仍在持续重塑这片地貌，不断剥蚀着质地松软的沉积岩，从而让数百万年的地球历史展露无遗。这些岩层分别由远古河流的沉积物、火山灰，以及该区域曾被浅海覆盖时期的沉积物交替堆积而成。

在这片崎岖不平的地表之下，埋藏着全球最丰富的化石群之一。这里保存了曾漫步于该区域的早期哺乳动物遗骸，例如古马类以及现代犀牛的近亲。然而，恶地国家公园不仅是一扇窥探过去的窗口。在当下，美洲野牛在开阔的普利里草原上觅食，大角羊在陡峭的嵴线间穿行，而黑尾土拨鼠则以活跃的集群形式聚居于草场之上。

景观公路与观景点顺应着地形的起伏绵延，为访客提供了极目远眺的壮阔视野。即便在此时此刻，随着地貌的缓慢演变，那些尘封于过去的岩层仍在不断破土而出。

Sunset in Badlands National Park, South Dakota

Layered ridges stretch across Badlands National Park in South Dakota. Their bands of pink, gray, and gold shift with the light as eroded peaks and valleys come into view. Wind and water continue to shape this terrain, steadily wearing away soft sedimentary rock and exposing millions of years of Earth's history in layers formed by ancient rivers, volcanic ash, and periods when shallow seas covered the region.

Beneath this rugged surface lies one of the world's richest fossil beds, preserving the remains of early mammals such as ancient horses and relatives of modern rhinoceroses that once roamed the region. The Badlands are only a window into the past. Today, bison graze the open prairie, bighorn sheep move along steep ridges, and prairie dogs gather in active colonies across the grasslands.

Scenic roads and overlooks trace the contours of the land, offering sweeping views. Even now, layers of the past continue to emerge as the landscape slowly transforms.

沉静的力量 Quiet strength

退潮时裸露在乌尔萨海滩海岸上的帽贝, 葡萄牙

乌尔萨海滩（Praia da Ursa）深藏在欧洲大陆最西端——罗卡角（Cabo da Roca）附近的陡峭悬崖之下，置身其中，仿佛来到了大陆的尽头。沿着一条狭窄崎岖的小径便可抵达这片隐秘的沙滩。在葡萄牙的大西洋沿岸，风、岩石与惊涛骇浪共同塑造了这里的地貌。当潮水退去，海岸线短暂地变得宽阔，平滑的岩石显露出来，随之而来的还有微小的生命迹象。帽贝紧紧贴在裸露的岩石上，在海浪平日拍打的地方顽强地驻守。

这些其貌不扬的海螺已完全适应了此地的环境：它们凭借强劲的吸附力与低矮的螺壳，从容抵御着海浪的冲击、气温的骤变以及长时间的离水曝晒。每逢涨潮或被海水淹没之时，它们便以海藻为食；待潮水退去，又会回到各自熟悉的栖息之地。乌尔萨海滩（Praia da Ursa）地处偏僻，正因如此，这些细微的瞬间往往容易被游人忽略，而一旦留心察觉，便会倍感惊喜与充实。在这片以宏大尺度与磅礴力量为主调的海岸景观中，哪怕是最微小的幸存者，亦折射出了大西洋海岸那份宁静而坚韧的生命力。

Limpets at low tide on the coast of Praia da Ursa, Portugal

Tucked away beneath steep cliffs near Cabo da Roca, the westernmost point of mainland Europe, Praia da Ursa feels like the edge of the continent. Reached by a narrow, rugged trail, this secluded beach along Portugal's Atlantic coast is shaped largely by wind, stone, and powerful waves. When the tide recedes, the shoreline briefly widens. Smooth rocks emerge, and with them, small signs of life. Limpets cling tightly to the exposed stone, holding fast where the ocean usually breaks.

These modest marine snails are well adapted to conditions here, using strong suction and low shells to withstand surf, shifting temperatures, and long periods exposed to air. During high tide or when submerged, they graze on algae, then return to familiar spots as the sea recedes. Praia da Ursa's isolation makes these moments easy to miss and rewarding to notice. In a landscape defined by scale and force, even the smallest survivors reflect the Atlantic coast's quiet resilience.

一抹蓝色 A splash of blue

赫瑙萨波鲁尔火山口湖, 冰岛

从空中俯瞰，湖泊平静的湖面与周围崎岖的地形形成鲜明对比。赫瑙萨波鲁尔火山口湖（也称布拉赫鲁尔湖）位于菲亚拉巴克自然保护区的中心地带，这片位于冰岛高地的偏远地区，其地貌更多地受到火山活动而非人类活动的影响。火山口的形成源于岩浆与地下水的接触，引发了一场爆炸，最终雕琢出如今可见的圆形盆地。

随着时间的推移，雨水、融水和地下水在盆地内积聚，形成了今天我们看到的这幅引人注目的湖泊景象。湖水的颜色会随着光线和天气的变化而变化，晴空万里时常呈现出碧绿的色泽，而云雾缭绕时则会变成深蓝色或灰色。周围的山坡上清晰可见火山物质的层理，记录着曾经席卷这片土地的多次火山喷发。

菲亚拉巴克至今仍基本保持未开发状态，其地质特征和广袤的开放空间受到保护。从空中俯瞰，很容易看出强大的自然力量如何塑造了赫瑙萨波鲁尔，以及冰岛高地为何持续吸引着游客——在这里，地球躁动不安的能量依然清晰可见。

Hnausapollur crater lake, Fjallabak Nature Reserve, Iceland

From above, the lake's smooth surface contrasts sharply with the rugged ground surrounding it. Hnausapollur crater lake—also known as Bláhylur—lies in the heart of Fjallabak Nature Reserve, a remote area of Iceland's highlands shaped more by volcanic activity than by human settlement. The crater formed when magma met groundwater, triggering an explosion that carved out the circular basin visible today.

Over time, rain, meltwater, and groundwater accumulated within the basin, forming the striking lake seen in today's image. Its color shifts with light and weather, often glowing turquoise under clear skies and appearing deeper blue or gray when clouds pass overhead. The surrounding slopes reveal distinct layers of volcanic material, recording successive eruptions that once spread across the landscape.

Fjallabak remains largely undeveloped, protected for its geology and vast open spaces. From this aerial perspective, it's easy to see how powerful natural forces shaped Hnausapollur and why Iceland's highlands continue to captivate visitors—a place where the Earth's restless energy remains visible at the surface.

品尝日落 Taste the sunset

韦尔纳扎, 五渔村, 利古里亚, 意大利

韦尔纳扎是意大利利古里亚大区五渔村的一个海滨小镇。它围绕着该地区唯一的天然港口而建，自古以来就与大海紧密相连。韦尔纳扎最早的文字记载可追溯到1080年，当时它是一个设防的定居点和海上基地，后来成为热那亚共和国海岸防御体系的一部分。时至今日，小镇依然保留着昔日的风貌，多利亚城堡的遗址和俯瞰海湾的瞭望塔诉说着它的历史。在水边，矗立着圣玛格丽塔·安提阿教堂，这座教堂最早的文字记载可追溯到1318年，并在之后的几个世纪中不断扩建，如今教堂的钟楼俯瞰着港口。房屋和狭窄的街道上方，陡峭的梯田上种植着葡萄园和橄榄树，这些梯田是由一代又一代的工匠用石头精心雕琢而成，构成了五渔村国家公园的景观，而五渔村国家公园本身也是联合国教科文组织世界遗产的一部分。想象一下这里的餐前小酌：一杯当地白葡萄酒，港口景色尽收眼底，还有利古里亚的特色美食，如佛卡夏面包和罗勒香蒜酱——简直就是一张可以品尝的明信片。

Vernazza, Cinque Terre, Liguria, Italy

Vernazza is a small seaside town in Cinque Terre, in Italy's Liguria region. Built around the area's only natural harbor, it has long been tied to the sea. First recorded in 1080 as a fortified settlement and maritime base, it later became part of the Republic of Genoa's coastal defenses. To this day, the village preserves its past in the ruins of Doria Castle and the watchtowers overlooking the bay. At the water's edge stands the Church of Santa Margherita d'Antiochia, first mentioned in 1318 and expanded in later centuries, with a bell tower overlooking the port. Above the houses and narrow lanes, steep terraces support vineyards and olive groves, shaped by generations of stonework in a landscape protected within Cinque Terre National Park, part of a UNESCO World Heritage Site. Picture an aperitivo here: a glass of local white wine, the harbor in view, and Ligurian favorites like focaccia and basil pesto—basically a postcard you can taste.

随波逐流 Drift with the current

世界海洋日

今天是世界海洋日，让我们跟随这种随波逐流的生物的脚步吧！想看看狮鬃水母吗？那就去寒冷的北方海域寻找吧。它的伞状体分为八个瓣状结构，伞状体下方垂着长长的触手和口腕。随着水流漂移，它身上的刺细胞会捕获浮游生物和小鱼。对人类来说，被蜇一下会很疼。每个人的反应都不一样，即使是搁浅在海里的触手也可能造成疼痛。所以，记住一条简单的原则：欣赏它，然后就不要打扰它。北极水域的一些狮鬃水母伞状体直径超过6英尺（约1.8米），但大多数目击到的都是风暴或强流过后靠近海岸的小型个体。

世界海洋日不是一场说教，而是一个提醒：海洋健康是一个环环相扣的链条，从浮游生物到捕食者，无一例外。减少一次性塑料的使用，支持更清洁的航运和捕鱼规则，并在你居住的地方支持栖息地保护。维护海洋的健康，野生动植物才能得以生存。

World Oceans Day

Today is World Oceans Day, so follow the lead of a creature that goes wherever the water takes it. Want to spot a lion's mane jellyfish? Look in cold northern seas. Its bell is split into eight lobes, and beneath it hang long tentacles and oral arms. As it drifts with the current, stinging cells snare plankton and small fish. For humans, the sting can be painful. Reactions vary, and even a washed-up tentacle can still hurt. The rule is simple: admire it, then leave it alone. Some lion's manes in Arctic waters have bells more than 6 feet across, but most sightings are smaller animals near shore after storms or strong currents.

World Oceans Day is not a lecture. It is a reminder that ocean health is a chain, from plankton to predators. Cut single-use plastic, back cleaner shipping and fishing rules, and support habitat protection where you live. Keep the ocean working, and the wild stays with it.

最后一堵墙矗立着 The last wall standing

北爱尔兰邓塞弗里克城堡遗址

在邓塞弗里克城堡，历史仿佛就悬挂在原地——确切地说，就悬挂在原地。残垣断壁依附在大西洋上方的玄武岩峭壁上，证明即使是废墟也能屹立不倒。两千年前，这里是爱尔兰五大道路之一——斯莱格·米德卢赫拉（Slige Midluachra）的终点，这条道路连接着通往塔拉山（Hill of Tara）王室的旅人。据说，公元5世纪，圣帕特里克曾到访此地，并为当地居民奥尔坎（Olcán）施洗。传说中，用于为爱尔兰国王加冕的“命运之石”（Lia Fáil）就是从这片海岸被带往苏格兰的。

维京人在9世纪末袭击了这里。1642年，苏格兰陆军军官罗伯特·芒罗将军破坏了城堡，后来在克伦威尔征服爱尔兰期间，城堡又遭到进一步破坏。然而，一座小塔楼一直屹立到1978年，最终被海水吞没。

如今，在国民信托的管理下，这里免费开放，保留着原始风貌，令人耳目一新——距离巨人堤道仅几步之遥。没错，这里是一处遗址——但它拒绝悄然消逝。

多走走，多思考 Wander often, wonder more

纳奇兹小径日出步道

如果你最近沉迷于电子屏幕，今天正是改变的好时机——我们建议你去徒步旅行。

今天图片展示的是位于密西西比州图珀洛附近的纳奇兹小径公园大道。这条小径几个世纪以来一直是美洲原住民的通道，在18世纪末19世纪初又为欧洲和美国的探险家和商人所用。如今，它绵延444英里，部分路段保存完好，展现了这条古道在经年累月的使用后逐渐下沉至周围地表的过程。沿途的指示牌详细介绍了这些历史，而大片森林和开阔的平原则让人可以放慢脚步，悠闲地欣赏沿途风光。

在山路上走走可以帮助减轻压力、改善情绪，还能缓解久坐带来的身体僵硬。因为活动恰逢周末，所以非常方便——走出去，稍微活动一下，剩下的就交给山路吧。

National Trails Day

If your screen time has been winning lately, today is a good time to change that—we suggest hiking. National Trails Day, created in 1993 by the American Hiking Society, nudges people toward exploring trails.

Take the Natchez Trace Parkway near Tupelo, Mississippi, featured in today's image. This trail was used by Native Americans for centuries before serving European and American explorers and traders in the late 18th and early 19th centuries. Now it covers 444 miles, with preserved sections showing how the original path sank below the surrounding land after years of use. Markers along the route explain these layers of history, alongside stretches of forest and open land that make it easy to slow down.

Time on trails can help lower stress, improve mood, and ease stiffness from long hours of sitting. Because it falls on a weekend, it's an easy win—step out, move a little, and let the trail do the rest.

无人问津之地的静默力量 The quiet power of an unclaimed world

世界环境日

如果大自然也有“请勿打扰”的标志，那它一定会挂在萨雷克国家公园上空，这里常被称为“欧洲最后的荒野”。在世界环境日这一天，瑞典拉普兰的这片偏远角落提醒我们，当人类退后一步，让大自然主导一切时，地球会是什么样子。

萨雷克国家公园成立于1909年，是欧洲大陆最古老的国家公园之一，至今仍未受现代基础设施的影响。这里没有标记清晰的步道，没有舒适的咖啡馆，更没有捷径。取而代之的是，它拥有200多座山峰、近100条冰川，以及由冰川和时间雕琢而成的山谷。萨雷克国家公园是联合国教科文组织世界遗产——拉普兰地区的一部分，也是萨米族原住民的家园，他们至今仍在这片土地上传承着驯鹿放牧的传统。

这里的野生动物行事低调——驼鹿、猞猁和狼獾都十分低调。就连河流也不愿停滞不前，在地貌中开辟出属于自己的道路。今天我们关注的是行动，但萨雷克也强有力地论证了不作为的必要性。有时，保护地球意味着要抵制驯服它的冲动。

World Environment Day

If nature had a 'do not disturb' sign, it would hang over Sarek National Park, often called 'the last European wilderness.' On World Environment Day, this remote corner of Swedish Lapland reminds us what the planet looks like when humans take a step back—and let the wild take the lead.

Established in 1909, Sarek is one of the continent's oldest national parks and remains untouched by modern infrastructure. There are no marked trails, no cozy cafés, and definitely no shortcuts. Instead, it offers over 200 peaks, nearly 100 glaciers, and valleys shaped by ice and time. It is part of the Laponian Area, a UNESCO World Heritage Site, and home to the Indigenous Sámi people, whose reindeer herding traditions still thrive across these lands.

Wildlife here plays it cool—moose, lynx, and wolverines keep things low-key. Even the rivers refuse to stay still, carving their own paths through the landscape. Today is about action, but Sarek makes a strong case for inaction too. Sometimes, protecting the planet means resisting the urge to tame it.

路之所止，行之所启 Where the road stops, the ride begins

世界自行车日

虽然日常的通勤之路或许不像今日画面中那般波澜壮阔，但这并不妨碍我们跨上单车，开始蹬踏。在“世界自行车日”到来之际，联合国向全球发出倡议，邀我们重新审视两轮出行的无限可能——无论是在穿梭于现代都市，还是纵贯于偏远荒原。每年的6月3日，这一由联合国发起的国际纪念日旨在认可自行车作为一种务实的出行方式，在促进公众健康、降低碳排放以及提升交通普惠性方面所发挥的关键作用。

画面中，一位探险者正骑行穿越西班牙纳瓦拉自治区的巴德纳斯雷亚莱斯自然公园。这片生物圈保护区呈现出一种苍凉的荒漠景观，是由风力与流水历经数百万年剥蚀而成。其间纵横交错的蚀余悬崖、台地与干涸河床，使其视觉质感比起西班牙北部，更像是某个遥远的外星天体。作为受保护的联合国教科文组织生物圈保护区，该公园允许在指定路径上进行骑行，为人们提供了一个以人类体能时速、近距离感受这一脆弱生态环境的珍贵契机。

World Bicycle Day

Your average route to work might not resemble the one in today's image, but it shouldn't stop you from pedaling. World Bicycle Day invites us to rethink what's possible on two wheels—whether the ride cuts through city streets or remote terrain. Observed every June 3, the United Nations–backed day recognizes cycling as a practical way to move, supporting health, lowering emissions, and making mobility more accessible.

An adventurer shown here cycles through Bardenas Reales Natural Park and Biosphere Reserve in Navarra, Spain, a stark landscape shaped by wind and water over millions of years. Its maze of eroded cliffs, plateaus, and dry channels feels closer to another planet than northern Spain. Protected as a UNESCO Biosphere Reserve, the park allows cycling on designated routes, offering a rare chance to experience a fragile environment at ground level and human speed.

From daily commutes to places like this, bicycles turn travel into exploration—quiet, efficient, and surprisingly bold.
