Which New Mexico mountain became the subject of Georgia O'Keeffe's painting Pedernal?

Cerro Pedernal became the subject of Georgia O'Keeffe's painting Pedernal.

Cerro Pedernal is a flat-topped mesa in northern New Mexico, near Abiquiú and Ghost Ranch. O'Keeffe could see it from her home and repeatedly painted and drew its distinctive profile. The mountain became one of the most recognizable landmarks in her New Mexico imagery.

O'Keeffe's statement that it was her “private mountain” is often quoted in discussions of the site. Her interest was not based only on a single view: she returned to the mesa in multiple works and from different visual approaches.

Cerro Pedernal should not be confused with the larger Sangre de Cristo mountain range or with Black Place, the dark cliff formation near Ghost Ranch. The word “Pedernal” appears in several O'Keeffe titles, but the geographic subject is specifically this isolated mesa.
