During the summer of 1923, the guide Célestin Bernard took charge of the construction of the refuge at Font Turbat. Several great mountaineering names are associated with it like Guery, Ripert, Frendo, Fourastier, Boell, who came to explore the mountains at Valjouffrey. In 1934, Devies and Gervasutti traced a historic itinerary in the North-West face of the Pic de l'Olan. 22 years later, the direct Couzy-Desmaison (ED) was opened to the left of the previous one, surmounting the steepest part of the face. The construction of the refuge As it stands now dates from 1962. It was extended and renovated in 1996-1997.
