Map of swirls between ±60° latitude.
Map of lunar swirls (±60° latitude) based on LROC Wide Angle Camera (WAC) color mosaic at a resolution of 400 meters/pixel. Swirls are sinuous, high-reflectance markings co-located with crustal magnetic anomalies. Their formation mechanism is not yet known but may be related to an altered or reduced space weathering environment. For details see: Denevi, B. W., M. S. Robinson, A. K. Boyd, D. T. Blewett, R. L.
