GROS•CAILLOU • 'Big Pebble' is a landmark of the French city of Lyon in the neighborhood La Croix-Rousse. The rock's mineralogical composition suggests it is a glacial erratic, and would have been transported from the nearby Alps by slowly moving glaciers. • The discovery of Gros Caillou - a metamorphic Triassic quartzite displaced by glaciers over 200 km during the Riss glaciation - dates back to 1861 during drilling of the tunnels of a funicular linking downtown Lyon to the Croix-Rousse plateau. The drilling had to be interrupted as the workers were blocked by an extremely hard rock, which they could not break. • Nowsday, the Gros Caillou is a playground for local children. • • • • • #onlylyon #igerstlyon #explorelyon #hello_France #cityoftheworld #europe_gallery #myspc #super_france_channel #traversefranse #rsa_streetview #urbandandstreet #groscailloulyon #travelwithme #livetotravel #travelphotography #travelcommunity #babestravelling #sheroams #theglobewanderer #topdestinations #beautifuldestinations #bbctravel #mytinyatlas #suitcasetravels #traveldeeper #huffposttravel #wellnesstravel #voyageenfrance #croixrousse #tbt (at Lyon, Rhône-Alpes, France) https://www.instagram.com/p/B-fixyLHqhz/?igshid=1fczwuna6rxs2
