The painting "Winter's day at Sils" Wintertag plant near Sils shows a sunny landscape in the snowy Engadin in Switzerland. A river leads through the snowy landscape, from which scattered boulders and leafless trees protrude. In the background rises a snowy mountain in front of the light blue sky. The snow cover is particularly thick, which can be traced by the footsteps leading away from the foreground and along the shoreline. Mönsted succeeds in reproducing the calm and cheerful impression of the magnificent snowy landscape.
