My Time at Modane The Laboratoire Souterrain de Modane, or LSM, is located directly adjacent to the Italy-France border. Nestled below the Frejus Peak and connected to the Frejus Road Tunnel (a 13km underground highway currently under expansion), the laboratory can be driven into and shields its projects with a maximum of 1700m of rock overburden (the equivalent of 4800m of water overhead, in terms of radiation protection). https:// steve.cooleysekula.net/blog/20 23/10/19/my-time-at-modane/
