Bierstadt Albert Figures in a Hudson River Landscape Albert Bierstadt (1830-1902)

The picture has something of this: landscape, dawn, outdoors, sunset, tree, grassland, mountain, nature, grass, hill, sky, scenic, desert, evening, fog, valley, field, dusk.
Perhaps it’s a painting of a mountain scene with a river in the foreground and a group of people on horseback on the other side of the riverbank.
