Georgia O'Keeffe spent much of her later life in New Mexico. She first visited the state in 1929 and later made it her permanent home, finding lasting inspiration in its desert landscapes, bones, cliffs, and adobe architecture.
She divided time between New York and New Mexico for years before moving permanently to the Southwest in the 1940s. The state's bright light and distinctive forms became central to her mature work.
O'Keeffe lived in Abiquiu and later maintained a home in nearby Ghost Ranch. She also spent time in Santa Fe, where she died in 1986. Her New Mexico subjects included animal skulls, churches, mountains, and broad expanses of sky.
New Mexico is sometimes loosely grouped with the American Southwest as a whole, but the answer to this question is the specific state. O'Keeffe's work helped shape international ideas about New Mexico's visual identity.
