This image shows the path the Mars Exploration Rover Spirit has traveled since it landed 53 martian days, or sols, ago. "Laguna Hollow," the shallow depression where Spirit dug a trench, can be seen to the right of center. Spirit stayed at "Laguna Hollow" for 3 sols, investigating the fine-grained soil contained there and the trench it dug with one of its wheels. The rover is headed northeast toward a large crater nicknamed "Bonneville." This navigation camera image mosaic was taken from the rover's new location, a region dubbed "Middle Ground" located 98 meters (322 feet) away from "Bonneville."
