BRIEF DESCRIPTION
22.4N 163.1W
Jackson is a very interesting and prominent lunar impact crater (71 km wide)  that is located in the northern hemisphere on the far side of the Moon. In Ridge Section 099 it is on the bottom right hand corner. See hi-res image of area from LRO's LAC 51 above. Jackson lies at the center of a large ray system. A skirt of higher-albedo material covers the surface within one crater diameter, with a slightly darker band along the outer ramparts. Beyond that radius, the rays form wide sections that grow increasingly diffuse and wispy with distance. The largest sections lie in roughly 90 arcs to the northeast and southwest, while a narrower arc projects to the south-southeast. The rays continue for hundreds of kilometers across the surface. The rim of the crater is well-defined and not significantly worn. The edge is somewhat polygonal in shape, with the southeastern rim being more rounded. The inner walls display some terracing. The interior floor is generally level with some irregularities in the northeastern part. Parts of the floor have a relatively high albedo. In Section 099 Cockroft is the top part of the big double crater to the North and Fitzgerald is the large crater right on the western edge. (Credit: Most of the information used in the section feature descriptions was obtained from wikipedia.org. Section 099 and this directory was created by Fran Ridge and Ned Haskin of The Lunascan Project).
