The tires on the rover are 8 inches high. That clump on the right tire looks at least 1 to 2 inches thick.
Moist powders would do that.
You suggest dry powders under the weight of the heavy rover would do that.
I'm doubtful but I'm willing to be convinced.
Each tire of the rover has to support 380/6 = 63 lbs. But Mars gravity is about .40 times that of Earth, so make this 25 lbs. Roll a wheel of this size supporting 25 lbs. in thick talcum powder or powdered sugar and determine whether or not you get a clump this thick.

        So does oily dirt. So does talcum powder. Not ready to make any conclusions. (n/t) - alcaray - 1/15/2004 6:13:06 PM
        
        So does a powder. Roll a toy car in icing sugar. (n/t) - Tony - 1/15/2004 6:10:18 PM
