Although Google maps is very good for finding locations of cities, towns, villages. and rivers, it is a bit lacking when it comes to topographical features, such as ridges, hills, etc.
Maps of France
Francois Lo Presti recently pointed out to me an on-line source of 1:50,000 scale maps for France. It is Geoportail: https://www.geoportail.gouv.fr
To access the 1:50,000 scale maps click on Cartes in the upper left corner and then on Carte IGN.
