Figure 1
This view of the lower portion of the martian rock called "Last Chance" (see PIA05482)
shows a close-up of texture interpreted as cross-lamination evidence
that sediments forming the rock were laid down in flowing water. NASA's
Opportunity took the original image during the rover's 38th sol in Mars'
Meridiani Planum region (March 2, 2004).
In the central part of the image, the dip of fine layers at angles to each
other (cross laminae) suggests that the water that created the
cross-lamination was flowing from left to right. Interpretive black
lines trace these cross-laminae. Interpretive blue lines indicate
boundaries of possible sets of cross-laminae (Figure 1).
Figure 2
A three-dimensional visualization of this portion of the rock offers
additional details of the cross-lamination (see PIA05626). The visualization and the
image from the panoramic camera are compared to show a point of
correlation (yellow arrow, Figure 2).
