Dated 1778, this small oil study by Caspar Wolf (1735–1783) shows the Geltenbach Falls in the Lauenen Valley.

Wolf is widely regarded as the pioneering figure of Swiss Alpine landscape painting, working nearly a century before the genre's nineteenth-century flourishing. This study relates directly to Wolf's finished painting in the Oskar Reinhart Foundation, Winterthur, Switzerland: The Geltenschuss in the Lauenen Valley with a Bridge of Snow, oil on canvas, 82 x 54 cm, signed – making this small panel a rare working study connected to a museum-held masterwork.

Collectors of eighteenth-century Swiss Alpine painting, Caspar Wolf's rare surviving oeuvre, and museum-related preparatory studies will find this an exceptional and scholarly significant example, published in From Fjord to Forest.
