What nickname did Georgia O'Keeffe give Cerro Pedernal, the New Mexico mountain she often painted?

Georgia O'Keeffe called Cerro Pedernal “my private mountain.”

Cerro Pedernal is a flat-topped mountain in northern New Mexico, near Ghost Ranch and Abiquiú. O'Keeffe repeatedly painted its distinctive profile, sometimes showing the mountain with broad, simplified planes and strong color contrasts. The landmark became one of the most recognizable natural forms in her New Mexico imagery.

Her phrase “my private mountain” expressed a personal artistic relationship with the site rather than legal ownership. O'Keeffe once wrote that she painted the mountain often because it was a shape she could see from her house and because she wanted to keep it in her visual world.

Cerro Pedernal is sometimes confused with the red cliffs of Ghost Ranch as a general landscape subject. They are connected geographically, but Pedernal is a specific flat-topped mountain. O'Keeffe’s nickname for it is the memorable phrase “my private mountain.”
