GENEVA (AP) — A small Alpine river dammed by a landslide that largely buried the Swiss village of Blatten is now flowing through the debris, and the level of a newly created lake that raised worries about potential new destruction has fallen, authorities said Saturday.

A huge mass of rock, ice and mud from the Birch glacier thundered into the Lötschental valley in southern Switzerland on Wednesday, destroying much of the village. Buildings that weren’t buried were submerged in a lake created by the small Lonza River, whose course was dammed by the mass of material.
