Event Finistérien "Le Champignon" EarthCache

English
Huelgoat is popular with tourists and holidaymakers due to its impressive natural setting among the vestiges of the ancient forest that once covered inland Brittany. Once part of royal and ducal lands, the forest is now overseen by the French forestry commission, the National Forests Office. It has an area of 10 square kilometres. A large replanting scheme has repaired much of the damage sustained by the forest in storms on the 15-16 October 1987, when 3.1 square kilometres of trees were levelled or damaged. The village lies on a lake created between the 16th and 18th centuries to supply water to local silver-lead mines by means of a 3 km (1.9 mi) leat or canal. A number of geological and prehistoric curiosities can be found by following trails in and around the village and forest.

The geological explanation of Huelgoat: these rocks come from the depths of the ground. Born with ten km of depth in the form of liquid masses in fusion, these masses will go up very slowly towards surface, will cool and be solidified with a few kilometers of the level of the ground. Then erosion, i.e. the rainwater and the streaming, freezing, heat will contribute to release, clear all the ground surmounting these rocks; it is thus released which one finds them today.

Among these are: « Le Champignon”, or The Mushroom, is a large rock balanced on a smaller one to give the eponymous appearance. To log this EarthCache you must photograph yourself or your GPS with the Mushroom, then you must estimate the approximate height of the rock“Le Champignon”.
