Whitehorse grew up on the open land northeast of Gallup, New Mexico in a family where only the Navajo language was spoken.
Through herding sheep and exploring nearby ruins, she developed an interest in light affects our perception of the environment--how clouds darken canyons, sunlight illuminates small flora and fauna, and the horizon line dissolves with dusk.
"[1] In 1980, Whitehorse earned her Bachelor of Arts degree in painting from the University of New Mexico in Albuquerque (UNM).
[7] Her paintings are usually oil on paper, mounted on canvas, such as Movement, in the collection of the Honolulu Museum of Art.
[9] Press coverage of the 2024 Venice Biennale, including the New York Times review, especially focused on Whitehorse and her prominent role in the exhibition.
