Fractures Fill Floor of Gleaming Martian Canyon

Water once coursed through Echus Chasma, a canyon incised across a Martian plateau. Here we see fractures meeting on the floor of the canyon.
Lava from a more recent eruption partially covers the blue bottoms of the fractures, captured here by NASA’s Mars Reconnaissance Orbiter.
