Views along the Río Magdalena, near Angostura, Colombia

Frederic Edwin Church's field sketches document a Colombian landscape survey. The upper drawing captures atmospheric effects across distant terrain in loose, gestural lines. Below, detailed botanical studies—including palm species native to the region—demonstrate the artist's dual commitment to landscape grandeur and scientific precision. Such sketches served as source material for Church's monumental studio paintings. These working drawings reveal the Hudson River School's methodology: direct observation in situ, combined with careful notation of exotic flora and geological formations, which would later be synthesized into heroic canvases celebrating American engagement with the natural world.
