The Greeley Panorama is the result of four and a half months of imaging at Opportunity's winter location, Greeley Haven. The team chose the site for its northerly tilt, to optimize solar gain during the winter months. The site's informal name is a tribute to the late Ronald Greeley, a geologist and former MER science team member. Greeley Haven is located on Cape York, part of the Western rim of Endeavour Crater on Mars. In this image, the crater stretches from the center to the right side. Because the panorama shows a full 360 degrees, the rest of the crater can be seen on the left side. The tracks in the center reveal darker soil under a thin layer of bright dust. Stretching along the bottom of the image is the rover itself, distorted because of the type of projection used. The Greeley Panorama is made up of 817 separate images taken by the Panoramic Camera (Pancam) between sols 2811 and 2947 (21 Dec 2011 to 8 May 2012). Pancam's 753, 535, and 432 nanometer (L257) filters were used to create the Greeley Pan. A separate deck pan portion using Pancam's 601, 535, and 482 nanometer (L456) filters has been color balanced to match the L257 view and included in this mosaic.
