Small marginal meltwater lake approximately at 628.500 / 90.540 (Swiss metric coordinate system).
The lake is easily visible from the path towards Gornergletscher near point 2658m (access to Monte Rosa-Hütte).
Looking over the lake downglacier. Arch-shaped ice lamellae show how the ice is supported by the moraine at both ends of the lake. The Matterhorn is in the background.
Panorama photo looking upglacier; note the person on the far end of the lake. Ice slabs leaning towards the lake will soon calve into it.
