Cabane perdue sur le plan du lai

The place

Shown on IGN maps from before 2010 (?) with a "cab" marker at this spot, but despite our extensive search (1 hour among the rocks and rhododendrons), nothing at all. Not even a wall or a roof. At the exact GPS position there is a huge boulder measuring 5x5 m (was the cabin crushed?). No, more likely an IGN error or a shelter dismantled since. Not to be confused with a chalet a bit lower down, near the source of the Goujon, called "cabane du plan du lai," with a doghouse, outdoor benches, positioned on the path but locked and unusable.
