Richard Wilson – Llyn-y-Cau, Cader Idris Tate Britain (London)

The picture has something of this: landscape, mountain, water, rock, nature, outdoors, scenic, valley, lake, volcano, hill, sky, daylight, environment, river, geology, hike, tree.
Perhaps it’s a painting of a mountain scene with sheep in the foreground and a body of water on the far side of the mountain.
