Tharsis Ridge
| |
| The Tharsis Ridge is the green/blue area in the middle of the picture, as well as a portion of the southern hemisphere of Mars. The green areas are higher than the surroundings, and the yellow/white regions, which are actually Martian volcanoes, are the highest of all. The red line in the picture is the Mars Global Surveyor spacecraft measurement which indicates just how large the regions are compared to one another. | |
