About Smoky quartz →

Geology of the locality

Setting
Valley in the Aar/Gotthard region with quartz-bearing Alpine clefts; Mindat describes the nearby Planggenstock as known for giant quartz crystals in clefts.
Region
Uri
Country
Switzerland

Photo labels give the valley only. Coordinates are those of Göschenen village at the valley mouth (Wikipedia), so the valley head, where the Planggenstock locality lies, is several km further west.
