The images combined into this mosaic were taken during Spirit's 653rd Martian day, or sol (Nov. 3, 2005), just before Spirit descended eastward onto "Haskin Ridge."

The view is about 150 degrees wide. It is an approximately true-color rendering generated using the camera's 750-nanometer, 530-nanometer, and 480-nanometer filters.

Dark features on the far side of the basin, just left of center in this view, are basaltic sand deposits that were emplaced on the lee sides of hills by northwesterly winds. Haskin Ridge is visible along the right margin of the image, capped by a light-toned layer of rock.

Spirit investigated the light-toned rock unit after taking this image. The basaltic plains located east of the "Columbia Hills" can be seen in the distance beyond "East Basin." The rim of Thira crater is just visible on the distant horizon some 15 kilometers (9.3 miles) away.
