January 26, 2026

A sunny day in early 2026 revealed the remnants of a winter storm on Arizona’s high desert—and produced a striking, if somewhat puzzling, display of light and shadow in the Grand Canyon. An astronaut aboard the International Space Station captured these photographs of the distinct topography on January 26, 2026.

Snow flurries were flying in the area the previous two days, as they were across much of the

to traffic in winter and early spring.) When the road reopened around the time of these photos, a layer of white remained on both the South Rim, at an elevation of around 7,000 feet (2,100 meters), and the North Rim, at about 8,000 feet (2,400 meters).

Snow is typical at these

If these photos make the iconic feature of the American West look more like a mountain range than a vast chasm, the effect is likely due to a visual illusion called

. Many people have an unconscious expectation that a light source should come from the top of an image. In these images, however, the Sun is shining from the south, or the bottom of the photos. Though the shadows on the canyon walls may be visually deceiving, the presence of snow helps to signal that the flat areas sit at higher elevations.
