The builders of this moraine landscape were two gigantic glaciers that converged at this place during the last ice age (ended about 12000 years ago) - namely the Reuss glacier and the Linth glacier. Now this is a lovely landscape near my home with smooth hills, Drumlins and little valleys catches the eye. It needs not great fantasy to imagine the former glacier flowing in this area. And that was a lot of up and down on todays bike ride.
