Ghost Ranch was Georgia O'Keeffe's ranch and landscape base near Abiquiú, New Mexico. She first visited the area in 1934 and rented a house there, later spending extended periods painting its cliffs, hills, bones, and changing light. The landscape became one of the defining settings of her mature work.
Ghost Ranch is known for its dramatic red and yellow formations, including Cerro Pedernal in the wider region. O'Keeffe painted the mountain repeatedly and treated it as a recurring visual subject. She also collected animal bones and used their shapes as sources for paintings and drawings.
The ranch is sometimes confused with O'Keeffe's Abiquiú home. They are separate places: Ghost Ranch lies north of Abiquiú, while the Abiquiú property became her principal home later. Ghost Ranch was also a guest ranch and is now associated with an education and retreat center, not solely with O'Keeffe's studio practice.
