English: This is the former drilling niche from 1943. Four core drillings were made from the bottom up in connection with a project of the Urseren power plants. Today there is a tunnel and angled a hall. As it seems, the niche was later equipped with masonry and used as a transformer station. It was found Louis Favre was in luck with the construction of the tunnel in those days. The overlap with bedrock is only 36 m at this point. Everything above it is loamy weathered ground with malleable character. It could have happened the same disaster as later during the construction of the Lötschberg tunnel. Because of the low permeability of the rock, there is no danger for the tunnel. At the time of the borings, about 3.5 liters of water per second were measured. The masonry archway in the background I can not assign. It looks as if there was once a passageway. Switzerland, Oct 26, 2015. (22/38)
