Water-carved valley on Mars. The researchers have found that some of these valleys appear to have been formed by orographic precipitation - rain or snow that falls when moist air is pushed upward by mountain ridges or raised crater rims. The findings suggest that at least some of the water on ancient Mars fell from the atmosphere, rather than bubbling up from the subsurface (NASA)
