Central Adiri geology. This figure shows a geological interpretation of the Central Adiri area before the change event, using an orthographic projection from above Adiri. Brown indicates dunes, green is equatorial bright material, yellow mountains, and blue icy outwash plains. Identification of mountains within the area with RADAR coverage is necessarily of higher fidelity than the identification of mountains from VIMS alone. At bottom left we also indicate the areas where VIMS sees surface changes in order to place them into context with the map.
