Catalogue Entry
Located in the Black Sand Basin in Yellowstone's Upper Geyser Basin, just to the west of Old Faithful, the Emerald Pool is one of the most jewel-like thermal features in the park. Here the warm water allows algae and bacteria to produce the pool’s rich range of turquoise and ultramarine tones. Around the pool is a white calcium rim. Standing near the pool's edge, Twachtman was probably looking north across its surface (fig. 1). It seems likely that he rendered his other view of this pool, Edge of the Emerald Pool (OP.1313) on the same day, depicting it from the opposite vantage point and cropping the pool more dramatically in the composition and shrouding it more in steam.
Here he juxtaposed the water's opalescence with the reflective surface of the obsidian ground cover. in this closely cropped image, Twachtman created a modernist conception of his scene by a strong forward tilt of his picture plane and a monumental rendering of the varied blues within the depths of the quiet thermal pool.
This painting was among Twachtman's Yellowstone works owned by William A. Wadsworth, the wealthy descendant of an illustrious Connecticut family, who provided the funding for the artist's trip to the Wyoming park.
From Kornhauser 1996
In Emerald Pool, Twachtman demonstrated exquisite handling of the sun-touched mists and the transparent green surface of the sulfur spring. Employing techniques characteristic of Impressionism, he used a lighter and brighter palette and loose airy brushstrokes that allow the canvas to show through. His flattening of natural forms into abstract shapes and sinuous outlines suggests a contemporary Art Nouveau aesthetic and reflects the artist's interest in Japanese art.
