阿尔卑斯山脉锡尔夫雷塔山的约里森湖，瑞士

今天我们要探索一处超凡脱俗的奇景：瑞士达沃斯附近的约里森湖群。天气晴朗时，湖面会呈现出不真实的蓝色，和周围灰暗、嶙峋的锡尔夫雷塔山形成鲜明的对比。阳光被水中的“岩粉”（湖床被冰川摩擦产生的细微的岩石颗粒）反射，形成了这种鲜艳的蓝色。锡尔夫雷塔山被冰川环绕，和碧蓝色的约里森湖一起被称为“蓝色锡尔夫雷塔”。如果你想亲眼目睹此景，要知道来到此地的路途并不容易。记得带上合适的徒步鞋、大量的饮用水和强健的双腿。

Jöriseen lakes in the Silvretta Alps, Switzerland

Today we're exploring a place of otherworldly beauty: the Jöriseen, a group of alpine lakes near Davos, Switzerland. On sunny days, the lakes glow an ethereal blue, contrasting with the dark, jagged Silvretta Alps that encircle them. The sunlight is reflected in the water by 'rock flour'—silt-sized rock particles generated from the grinding of bedrock by glaciers.

The Silvretta Alps sit across the Swiss-Austrian border and are themselves surrounded by glaciers in an area known as the 'Blue Silvretta.' If you want to enjoy these stunning views up close, you'll have to work for it. Bring your best hiking boots, plenty of water, and some strong legs.
