Lake Hoare, Antarctica, 1998 Photograph by Maria Stenzel 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 the nearby dry valley, warms in the sun, and
melts downward, leaving a bubble column in its trail.

(Text adapted from and photograph shot on assignment for, but not
published in, "Timeless Valleys of the Antarctic Desert," October 1998,
National Geographic magazine)    RELATED
