"Poptart" Rock
Source: Rover Front Right Camera Pop-tart, a small
rock or indurated soil material was pushed out of the surrounding drift material by
Sojourner's front left wheel during a soil mechanics experiment.
"Pooh Bear" and "Piglet" Rock
Source: Rover Front Right Camera
The Rover is located next to Pooh bear(rock at left) and Piglet (not
seen)as it looks out toward Mermaid Dune. The soil textures differ from the foreground
where the soil a poorly sorted mix of small rocks, fines and clods to the area a bit ahead
of the rover where the surface is covered with a bright drift material.Soil experiments where the rover wheels dug in the soil
revealed that the cloddy material exists underneath the drift.
"Yogi" Rock
Source: IMP
The Rover, while on its way to Yogi, performed several soil mechanics
experiments. Piles of loose material churned up from the experiment
are seen in front of and behind the Rover. Pop-tart is visible near the front right rover
wheel.
"Shaggy" Rock
Source:IMP
The IMP caught this image of the Rover as it was digging in the
"compressible" material near Casper to determine the soil's mechanical
properties.Shaggy is the large rock behind the Rover.
