The slopes necessary for the organization of a special slalom must present relatively stiff characteristics and the equipment of a slalom stadium in the immediate proximity of the finishing zone required very important earth works; the natural terrain was in fact cut by a deep ravine, which had to be filled in, and marked by two rocky ridges which were blasted.
More than 200,000 m3 of rock embankment had been made before the International Weeks. During these events, the summit zone of the Men's special slalom was judged to be still too flat and a starting hillock, 20 m High (35,000 m3 of rocky material) was heaped at the summit of this trail during the summer of 1967.
The work begun in July 1967 was completed in three months. It was financed by the Department of the Isère, which received a grant of 80% from the Ministry for Youth and Sport. It amounted to 4,400,000 F.
