"CergaNW" is the closest borie we know of to the CERGA observatory area of the Plateau de Calern. It's located northwest of the easily recognisable moon laser dome, the most northerly structure of the observatory.
The CergaNW borie is small. It's intact, but the exterior is quite disheveled, as if it has been clambered over.
The borie is positioned near the edges of a shallow doline, a flat, circular, grassy area. It blends in perfectly with the stones of the plateau, of which it is made.
