Bright ridged plains observed (a) at high (77.6°) incidence angle (low sun), highlighting topography: (Galileo 03837186.00, orbit E6ESBRTPLN02, near Conamara Chaos, 15°N, 86°E), (b) at medium (30°) incidence angle (high sun), showing albedo and topography (mosaic of Galileo 04262728.11,.18,.14, orbit 12ESWEDGE_02, near 17°S, 162°E), and; (c) at low (6°) incidence angle (almost overhead sun), showing albedo features (Galileo 04409488.52, orbit 14ESDRKSPT01, at 0°S, 135°E).
