Once the milking season was over, shepherds and their flocks would reach the Combalou pastoral routes via the slopes to the rear of the Combalou plateau rather than climbing up the cliff using the ladders. Shepherds used these ladders to scale down directly to Roquefort and climb up the same pathways when the ewes needed to be sheltered in the jasse. The flocks would be kept on the plateau until the first cold of autumn.The jasse was a two storey building: the ground-floor consisted of two sheepfolds, one of which had a vaulted ceiling, the first floor was a huge barn used to store the hay.
