Depth of the lunar dust.

The appearance of laboratory craters overlain by various thicknesses of sand has been compared with that of lunar craters, 3 to 13,000 meters in diameter, shown in ten photographs obtained by the Ranger 7 spacecraft. Results obtained are consistent with an interpretation that at least 5 meters of granular material, and probably considerably more, is deposited on the area of Mare Cognitum shown in these photographs.
