Which would be wrong though. Density wise the Martian atmosphere is closer to 2% the density it is on Earth, but wind would still exert roughly 1/9 the force it would here on Earth, not counting low gravity. A 60 mph wind on Mars (fastest average windspeed in a dust storm) would feel like a 7 mph wind on Earth, and could pick up things similar to a 20 mph wind because of the lower gravity. Still probably not enough to pick up a metal tube filled with rock though.
