Serpentine curves inspired by natural forms were a mainstay of O’Keeffe’s art from the earliest years of her career. Later on, she found new pictorial opportunities in the aerial view; which she discovered when she flew across the country and around the world in the lower-altitude propeller planes of the 1950s and 1960s. In this work, which suggests the ribbon-like meander of a Western river through and terrain, her reference to place is almost entirely subsumed by the force of the calligraphic, abstract designs.
