Mountains near Guanujo and Guaranda, Ecuador

Frederic Edwin Church's pencil study captures the layered topography of the Ecuadorian highlands with meticulous linear detail. The artist's systematic cross-hatching renders depth and atmospheric perspective across successive ridges, while touches of blue watercolor—possibly added later—mark a glacial lake nestled in the valley. This working drawing reflects Church's documentary approach to landscape, combining scientific observation with aesthetic composition. Such field studies formed the foundation for Church's grand exhibition paintings, which brought exotic geographies to American audiences during the height of Hudson River School Romanticism.
