Forkortet:The railway from Trondheim to Sweden runs East through the Stjørdal.The lower part of this valley is open and wide. About 9 km from the sea, themain river is joined from the north by the small river Gråelven which is sonamed because its water is gray colored after having flowed through a deposi ofmarine clay. The area of clay is surrounded by a rim of sand and gravel whoseupper surface is very distinctly marked where it runs along the slopes of theadjacent mountains. This rim is 165 m above the present sea-level, it indicatesclearly the maximum amount of the submergence of the land in this region whichoccurred at some period subsequent to the Great Ice Age for above this height,165 m there are no signs of marine action. The shells found in the clay belongto mollusca still living in the neighbouring sea. The district of Gråelven isshown on the map (p.34). The landslip occurred on the 16th August 1893 in themidst of the clay district, and is indicated by dots. A map on a larger scaleis given on p.36. The dotted part represents the area from which the clay hasslid away and the shaded part represents the area which is overflowed andcovered in the bottom of the small valley previously excavated in the clay bythe Gråelv. On the dotted area the clay to a depth of from 8 to 10 m, in allabout 800 000 m3 has literally flowed away.
