大西洋雕琢而成的加拿大 Canada, carved by the Atlantic

地牢省立公园，加拿大

位于纽芬兰岛博纳维斯塔半岛的地牢省立公园，长期受到大西洋海浪的塑造与侵蚀。公园最著名的景观“地牢（Dungeon）”实际上是一处巨大的塌陷海蚀洞，其顶部因持续侵蚀而坍塌，形成直通天空的壮观开口。这一地貌生动展示了海洋作用如何在数千年间不断改造坚硬岩石。

公园周围的悬崖主要由数亿年前形成的沉积岩构成。砂岩与页岩层记录着远古环境演变的痕迹，其形成时间甚至早于现代大西洋的出现。如今，海鸟、滨海植物以及沿岸洋流共同维系着这片充满活力的海岸生态系统，并持续影响着当地自然环境的发展。

地牢省立公园所在海岸位于西北大西洋重要的海鸟迁徙通道上。每年较温暖的季节，游客有机会看到三趾鸥、海鸠以及北方塘鹅等海鸟在悬崖与海面之间翱翔。丰富的海洋营养物质与崎岖的海岸环境共同构成了理想栖息地，使这里成为众多海洋生物的重要庇护所.

Canada Day

On July 1, Canada celebrates its national day, marking the events of 1867, when the British North America Act (now called the Constitution Act, 1867) united three British colonies into one Dominion.

In 1879, July 1 became a federal holiday, originally called Dominion Day before being renamed Canada Day in 1982. Today, people gather across the country for concerts, community events, and fireworks—celebrations that reflect a shared sense of identity and history.

Today's image takes us to Dungeon Provincial Park on the rugged coast of Newfoundland and Labrador, where nature tells a much older story. Atlantic waves carved a sea cave with two openings, gradually widening it until the roof gave way. What remains is a striking collapsed formation known as a 'gloup,' surrounded by steep cliffs and crashing surf. Boardwalks and viewing platforms allow visitors to take in the scene, while nearby trails offer sweeping ocean views. This dramatic coastline highlights the natural forces that are still shaping Canada's landscape today.
