Ice caves are underground cavities whose morphology creates microclimatic conditions that favor the development or maintenance of perennial ice accumulations (glacial ice or water ice). While primarily found in mountainous regions, they are often located in areas where the average surface air temperature is positive. As such, they are considered ‘periglacial’ phenomena situated beyond the typical boundaries of the cryosphere, with ice caves acting as natural cold traps. Historically, the ice from many ice caves was harvested to supply dispensaries and inns, sometimes located dozens or even hundreds of kilometers from the original cave. Although this practice continued until the early 20th century, the use of ice caves, as highlighted by various historical accounts, has often evolved in response to new demands, influenced by the accessibility and characteristics of the sites. This presentation examines how the use of three French ice caves has changed over the past few centuries: the Grotte de la Glacière in Chaux-lès-Passavant (Jura Massif, Doubs), the Grande Glacière du Parmelan (Bornes Massif, Haute-Savoie), and the Cave à Glace d’Anterne (Fiz Massif, Haute-Savoie). Their varying altitudes and degrees of accessibility have led to very distinct historical trajectories.
