中文注释:

在南极洲终年冰雪覆盖的霍尔湖,布满了泥沙的痕迹,这些泥沙由表面渐渐进入冰层中。泥土由附近一个干燥峡谷中被吹到结冰的湖面上,阳光使其升温,慢慢融入冰层以下,它的踪迹便形成一个个气泡柱。

文字及图片为国家地理杂志1998年10月《永恒的南极洲沙漠峡谷》一文而作,未刊发。

英文注释:

Ice Trails, Lake Hoare, Antarctica, 1998

Antarctica's perennially ice-covered Lake Hoare bears the scars of sand and dirt that have worked their way from the surface down into the ice. Soil blows onto the lake from a nearby dry valley, warms in the sun, and melts downward, leaving a bubble column in its trail.
