Between flowers and stone
Dominating Vieille-Vieille an educational hiking path enablers the discovery of some ecosystems of the "adret" (mountains slopes facing the sun) of the Guil's valley.
Before starting, note the name of the plants that give their name to this path. Let A be the number of letters of the plural form of the name. These plants of the legume familly (Fabacae) are known to have the medicinal properties to enhance tonicity and resistance to cold temperatures.
Follow the signs to the "Pierre Fiche" a standing stone that, according to the legend, was installed by 3 sherpherds to mark the limit of their territories, when they settled back in the valley after an invasion of the saracens. The stone used to be 7 meters high but was broken during the XIXth century. Let B the 3rd digit of the date carved in the megalith.
Supplementary question to be solved before starting: Ville-Vieille (the village below the path) once was the location of the secretary of the Escaron of Queyras, a group of villages with special rights founded in the XIVth century. The old townhouse still contains the old archive wooden cupboard of the escarton which could only be open with all the keys associated to the different villages of the valley. Let C be the number of locks of the cupboard.
The cache is located at N44 46.(C-B)(B-1)(A-C) E6 49.B(A-B)(C-2).
The coordinates of the cache description point to the beginning of the hiking trail (parking available).
After logging the cache, one can follow the ascending hiking path then take a driving trail to the west to reach the hamlet of Meyriès then go down a hiking path back to the car park. This itinary provides good views on the castle of Château-Queyras and passes by nice chapels, oratories and sundials.
