By Sol 29, Curiosity had driven a total of 358 feet (109 meters). The Glenelg area farther east is the mission's first major science destination, selected as likely to offer a good target for Curiosity's first analysis of powder collected by drilling into a rock
Glenelg marks the intersection of three kinds of terrain. One of the three terrain types is light-toned with well-developed layering, which likely records deposits of sedimentary materials. There are also black bands that run through the area and might constitute additional layers that alternate with the light-toned layers. The black bands are not easily seen from orbit and are on the order of about 3.3-feet (1-meter) thick. Both of these layer types are important science targets.
Then, the rover will aim to drive to the blue spot marked "Base of Mt. Sharp", which is a natural break in the dunes that will allow Curiosity to begin scaling the lower reaches of Mount Sharp. At the base of Mt. Sharp are layered buttes and mesas that scientists hope will reveal the area's geological history.
