This NASA color handout image, received on June 24, 2008 taken by the Surface Stereo Imager on NASA's Phoenix Mars Lander shows the trench dubbed "Snow White," after further digging on the 25th Martian day, or sol, of the mission (June 19, 2008). The lander's solar panel is casting a shadow over a portion of the trench. The trench is about 5 centimeters (2 inches) deep and 30 centimeters (12 inches) long.
