Canada Glacier: a Wall of Ice 150 Feet High Frozen tongues thrusting into Taylor Valley create a natural laboratory for scientists. Ero sion, evaporation, and summer's melt have kept mile-wide Can ada Glacier at a standstill for half a century. Thaw water grooves its face. Lake Bonney, a paradox in frozen Antarctica, mirrors the Kukri Hills, part of a wall bar ring the icecap from Taylor Valley. Bare earth describes the climate: arid. A lily pad of ice clings to the bottom of a small lake near McMurdo. Solid in winter, the pool melts from the top in sum mer. Algae, one of the area's few living things, cover the slopes. A visitor tries an icy foot bath.
