Scoria:

Some of the rock fragments near the landing site and next to 'the magic carpet' looked like these Volcanic Ash samples. Although, these are magnified:

The two words are vesicles for the gases trapped in igneous rock and "wind made" is ventifact. Wind erosion is evident all over the Earth. The thing that seems lacking in the images of Mars boulders and rocks is rounding. It seems there isn't much water in Gusev and hasn't been for a very long time...if ever.

Yes, Chris, but, and I'm not hinting that there may have been water in Gusev, we're only looking at the surface.

      • At this stage the evidence is overwhelming there is current liquid water on Mars. - Robert Clark - 1/17/2004 8:15:35 AM

          • Temperatures and pressures are within the range to permit liquid water in Gusev, Mars. - Robert Clark - 1/18/2004 1:38:16 AM
            • Bob, when the data shows you to be wrong, will you admit it? - R.L. - 1/18/2004 1:59:38 AM
              • When will you actually LOOK at the data showing temperature above freezing and pressure above 6.1 mbars? (n/t) - Robert Clark - 1/18/2004 11:49:21 AM
