Glaciers aren't the only things that create gravel here on Earth; flowing water, freezing/thawing and volcanic activity all can make littler rocks out of big ones, too. Being in an impact crater, I suspect Curiosity is driving on gravel made primarily by the meteor that created the crater in the first place.

<<Gravel play is composed of unconsolidated rock fragments that have a general particle size range and include size classes from granule- to boulder-sized fragments. Gravel is sub-categorized by the Udden-Wentworth scale into granular gravel (>2 to 4 mm) and pebble gravel (>4 to 64 mm). Large gravel deposits are a common geological feature, being formed as a result of the weathering and erosion of rocks. The action of rivers and waves tends to pile up gravel in large accumulations. This can sometimes result in gravel becoming compacted and concreted into the sedimentary rock called conglomerate. Quarries where gravel is extracted are known as gravel pits. Southern England possesses particularly large concentrations of them due to the widespread deposition of gravel in the region during the Ice Ages.>>

Curiosity, the big rover of NASA's Mars Science Laboratory mission, will land in August 2012 near the foot of a mountain inside Gale Crater. The mission's project science group is calling the mountain Mount Sharp. This informal naming pays tribute to geologist Robert P. Sharp (1911-2004), a founder of planetary science, influential teacher of many current leaders in the field, and team member for NASA's early Mars missions.

This oblique view of Mount Sharp, is derived from a combination of elevation and imaging data from three Mars orbiters. The view is looking toward the southeast. Gale Crater is 96 miles (154 kilometers) in diameter.

Yeah but the real name is Aeolis Mons.

There was no need to overwrite an existing name.

• In that case, the real name is "Mount Sharp":

<<Discovered in the 1970s, the mountain remained nameless for perhaps 40 years. When it became a likely landing site, it was given various labels; for example, in 2010 a NASA photo caption called it "Gale crater mound". In March 2012, NASA unofficially named it "Mount Sharp", for American geologist Robert P. Sharp.

The International Astronomical Union, which is responsible for planetary nomenclature for its particpants, names large Martian mountains after the Classical albedo feature in which it is located, not for people. In May 2012 the IAU thus named the mountain Aeolis Mons, and gave the name Aeolis Palus to the crater floor plain between the northern wall of Gale Crater and the northern foothills of the mountain. In recognition of NASA and in honour of Sharp, the IAU gave the name "Robert Sharp" to a large crater (150 km in diameter), located about 260 km west of Gale Crater, following its standard practice of naming large craters after scientists.

NASA and the ESA continue to refer to the mountain as "Mount Sharp" in press conferences and press releases. This is similar to other informal names, such as the Columbia Hills near one of the Mars Exploration Rover landing sites. Sky & Telescope explained the rationales of the two names to their readers in August 2012, and held an informal poll to newsletter readers. Over 2700 voted and picked Aeolis Mons over Mount Sharp by 57% to 43%. The official name, Aeolis mons, is recorded by the United States Geological Survey. Aeolis is the ancient name of the Izmir region in western Turkey.>>

In NASA News release 2012-260 dated August 27 2012 it states "Curiosity already is returning more data from the Martian surface than have all of NASA's earlier rovers combined". That surprised me greatly! The "eventual destination" in the explanation brings up a fascinating time-lapse video showing Spirit rover's entire 4.8 miles journey over 5 years 3 months 27 days. I still have a fondness for Spirit (not dead, just having a good rest I reckon after its epic trip!) and its buddy the still ongoing Opportunity rover.

<<Opportunity Exceeds 35 Kilometers Of Driving!
- sols 3051-3056, August 23-28, 2012:

On Sol 3051 (Aug. 23, 2012), Opportunity continued to move about 30 meters south along the inboard edge of Cape York, imaging the outcrop to the west with both Panoramic Camera (Pancam) and Navigation Camera (Navcam). On Sol 3053 (Aug. 25, 2012), the rover drove further south with more of an inboard bias to be closer to the outcrop. Again, more detailed Pancam and Navcam surveys were performed. On Sol 3055 (Aug. 27, 2012), the Rock Abrasion Tool (RAT) on the end of the robotic arm was imaged to re-confirm the available bit for future grinding and the Alpha Particle X-ray Spectrometer (APXS) collected a measurement of atmospheric argon.

On Sol 3056 (Aug. 28, 2012), Opportunity headed almost due west in a direct approach to some exciting outcrop units. With that drive, the rover passed 35 kilometers of odometry. Not bad for a vehicle designed for only about 1 mile of distance and 90 sols of lifetime.

As of Sol 3056 (Aug. 28, 2012), the solar array energy production was 568 watt-hours with an atmospheric opacity (Tau) of 0.570 and a solar array dust factor of 0.684.

Total odometry is 21.76 miles (35,017.33 meters).

Hopefully curiosity is a good climber.
