From images hidden by cartographers in maps of Switzerland that have been published by the Swiss Federal Office of Topography.

A man overlooking the town of Interlaken from a summit
A naked woman reclining by a river in the countryside of Egg
A hiker, with boots the size of a house, ascending an Italian slope
A white spider crawling up a technical passage of the Eiger
A freshwater fish swimming in the marshy zone of Lac de Remoray
A marmot crouching on a rock face in the Alps
