背景知识:
奇科帕尔大理石洞沐浴在布宜诺斯艾利斯湖的深蓝色湖水中,这些大大小小的洞穴都由同一块大理岩形成。布宜诺斯艾利斯湖的湖水来源于巴塔哥尼亚的高原冰川,冰川冰包裹着很多小颗粒,当冰融化以后,小颗粒们就在水中悬浮着,微浑浊的冰川融水会折射阳光中的蓝色光,因此布宜诺斯艾利斯湖才会呈现出如此明显的蓝色。

It's taken 6,000 years for nature to carve these remarkable formations. The marble caves of Chile Chico are located on a peninsula of solid marble bordering a remote glacial lake that spans the Chile-Argentina border. The lake is fed by rivers coming from several surrounding glaciers. As the glaciers melt and grow, the waters slowly carve out the marble leaving behind masterpieces fit for a museum. These distinct bright blue waters are caused by suspended particles from the glaciers reflecting the blue part of sunlight. Getting to this location isn't easy. It's a long journey requiring a flight, a 200-mile drive into the wilderness and a boat ride just to get there, but it's worth it. The remarkable swirling patterns on the cave reflect the lake's blue waters changing with the water levels and the season. Nature truly is the greatest artist.
