Tasman Lake, Aoraki/Mount Cook National Park, New Zealand.

Tasman Lake has formed as the Tasman Glacier retreated over the last 20-30 years. Tour boats ply its grey waters, giving visitors a close encounter with the lake's many icebergs and a view of the glacier's snout. The glacier's barren lateral and terminal moraines line the rest of the lake's coastline. Aoraki/Mount Cook (at far left) overlooks the lake.
