冰层中气泡奇观 Bubbles, bubbles everywhere

亚伯拉罕湖，阿尔伯塔省，加拿大

听说过冻住的泡泡吗？每到冬季，加拿大阿尔伯塔省的亚伯拉罕湖便会上演这一奇观，这些气泡不仅美丽，更是科学的结晶。建于1972年的亚伯拉罕湖是一个占地超过20平方英里的人造湖，沿北萨斯喀彻温河延伸。湖泊的水源来自落基山脉的冰川融水，即使在寒冬，湖水依然清澈透明。冰川融水携带的细小沉积物能够散射阳光，而岩石的天然过滤作用将污染物降至最低。

冬季的亚伯拉罕湖吸引了来自世界各地的摄影师和游客，他们渴望在这里目睹这一罕见的奇观：冰冻气泡。湖床上的腐烂植物会释放出甲烷等气体，当气温降至一定程度时，涌向湖面的气体被冰层锁住，形成了大小不一、形态各异的气泡层。更令人惊奇的是，这些绚丽壮观的气泡虽冻结在脚下，却高度易燃。一月至二月冰层最厚，气泡也最为清晰可见。如果你计划前往参观，尽量在靠近岸边的区域活动，以确保安全。

Abraham Lake, Alberta, Canada

Ever heard of frozen bubbles? Abraham Lake in Alberta, Canada, has them during the winter, and they're not just beautiful—they're science in action. Created in 1972, Abraham Lake is a human-made reservoir that spans more than 20 square miles along the North Saskatchewan River. Thanks to glacier-fed waters from the Rocky Mountains, the lake stays transparent even in the coldest months. Glacial meltwater carries fine sediment that scatters sunlight, while natural filtration through rocks keeps pollutants to a minimum.

The snowy season attracts photographers and visitors from around the world who are eager to capture a rare sight at Preacher's Point: bubbles. These frozen globes form when microorganisms break down dead plants and animals on the lake bed, releasing methane. As the gas rises, it gets trapped by the ice, creating layers of bubbles in various sizes and shapes. It's wild to think that they're flammable and chilling under your feet. The ice is thickest in January and February and the bubbles clearly visible. If you're planning to check it out, just remember to stick close to the shoreline for your safety.
