Image shows the variety of ridges on Mars.

Summary[edit]

Description
English: Image shows the variety of ridges on Mars. Ridges sometimes form shapes at nearly right angles. We do not know the exact cause, but a popular idea is that minerals were deposited in cracks. Later, erosion removed the soft material around them. There is some evidence that clays are near them. That's important because clays need water to form. Hence, they may be markers of past water. Some images contain boxes. The box represents the size of a football field (100 yards). The colored ones are from a colored strip in the center of each HiRISE image. All images were from the HiWish program that Jim Secosky used. The program HiView was used to modify most images.

Jim Secosky requested NASA take images through the HiWish program.

He then used HiView program to modify images. The image credit should be: NASA/JPL-Caltech/UArizona/Secosky.
