Spirit Rover Timeline For 2005 April - Mission Timeline - 2004 - Lahontan Crater

Lahontan Crater

It then reached Lahontan crater on Sol 118, and drove along the rim until Sol 120. Lahontan is about 60 yards (55 m) across and about 10 yards (9.1 m) deep. A long, snaking sand dune stretches away from its southwestern side, and Spirit went around it, because loose sand dunes present an unknown risk to the ability of the rover wheels to get traction.
