The physicist John Tyndall recounts his Alpine seasons: crossing the Lauwinen-Thor, a fatal accident on the Col du Géant, attempts on the Matterhorn, setting thermometers on the summit of Mont Blanc, and wandering the Grimsel, the Aeggischhorn and the Bel Alp. Climbing narratives alternate with observations on glaciers, ice and the shaping of valleys.
