Catalogue Entry
Located in Yellowstone’s Upper Geyser Basin, north of Old Faithful, the Morning Glory Pool was named for its resemblance to the shape of the corolla of the morning glory flower, while its hot temperature is responsible for its dazzling ultramarine and turquoise hues (fig.1). The pool has a glistening translucency, which Twachtman conveys here. In the work, he took an overhead perspective on the scene, capturing the colors bleeding upward from the pool's depths. He recorded the shift of tone from the waterway's grayish yellow outer orbital edge encircled by a white rim against the similar muted hues in the ground cover. Hiram Chittenden's description of this site 1895 seems to describe this painting: “In this beautiful object the quiescent pool is at its best. The exquisite bordering and the deep cerulean hue of its transparent waters make it, and others like it, objects of ceaseless admiration”1
This work was probably A Pool—Yellowstone Series (oil, 30 x 25 inches), included as number 49 in the artist’s estate sale; the painting sold to an individual named W. M. Clancy. In 1928, when it was in an auction at the American Art Association, it was titled Misty Morning. Confusingly in his Catalogue G, Hale used Morning Glory Pool as an alternate title for The Emerald Pool (OP.1312).
