In the 18th and 19th centuries the glacier descended all the way down to the hamlet of Les Bois, where it was known as Glacier des Bois. At that time the river Arveyron emerged from the glacier under a grotto-like vault ("grotte d'Arveyron") and, through the accounts of early writers and explorers, attracted many more visitors, painters and later photographers, for example Joseph Mallord William Turner's "Source of the Arveron in the Valley of Chamouni Savoy", 1816. The position of its front end fluctuated over the years but its maximum extent was in the mid-19th century.
