The Crêt de la Neuve is a mountain ridge in the Swiss Jura . The summit, which is 1495 m above sea level. M. , is located above the village of Saint-George in the canton of Vaud , around 15 km north of the city of Nyon . The area of the Crêt de la Neuve is part of the Parc jurassien vaudois .
The Crêt de la Neuve is part of the foremost Jura chain, which extends in the south-west-north-east direction of Saint-Cergue over the pass of the Col du Marchairuz to Mont Tendre . The ridge is bounded in the northwest by the Combe des Amburnex , a longitudinal hollow in the High Jura. To the southeast, the ridge gradually slopes down towards the Lake Geneva basin, with the plateaus (around 800 m above sea level ) above the Vaudois Côte in front of the Jura foot . To the northeast, a long ridge, which is always at least 1400 m high, leads over to Mont Tendre. Towards the southwest the ridge slowly descends and ends at the valley of the Ruisseau de la Combe , a source stream of the Serine in the catchment area of the Promenthouse . The Crêt de la Neuve is forested almost to the top.
In structural and geological terms, the Crêt de la Neuve forms an anticline of the Jura folds . The mountain peak consists of competent limestone from the younger Jurassic period ( Malm ), mainly from limestone from Portlandia, which was deposited in a tropical flat sea around 140 million years ago and unfolded from the late Miocene with the formation of the Jura Mountains. Due to the limestone, karst phenomena such as sinkholes and cart fields can be observed here. On the eastern slope of the Crêt de la Neuve is the Glacière de Saint-George , one of the few ice caves in the Jura.
