Image showing the dome Grimaldi 1 and Cavalerus 1 (described in plate Cavalerius region Quadrant I).

The height of Grimaldi  dome is determined to 160 ± 20m, resulting in an average slope of 0.6° ± 0.10°. The dome volume V is estimated by assuming a form factor of f = 1/2, which yields an edifice volume of 41.2km³. 

Some prominences, presumably non-volcanic hills, are situated on the summit of Grimaldi 1. The orbital image shows that the examined large dome displays linear structures on its surface that can be interpreted as the result of tensional stress. It belongs to class In1.
