eponym=Marsh of EpidemicsPalus Epidemiarum (
latin for "Marsh of Epidemics") is a smalllunar mare in the southwestern part of theMoon 's near side. It lies to the southwest ofMare Nubium , and southeast ofMare Humorum . This feature forms a rough band oflava -flooded terrain that runs generally west–east, with a northward extension near the western end.This mare is notable for a system of
rille s in the western end named the Rimae Ramsden, and for the wide Rima Hesiodus that extends from near the mid-point to the east-northeast roughly 300 km. The flooded crater Capuanus is occupies the southern center of the Palus Epidemiarum, and is attached to the southern edge. Near the western end is the flooded crater Ramsden, after which the Rimae Ramsden are named. The crater Cichus forms the eastern end of the mare.The northern extension of the mare reaches the outer rims of the crater pair Campanus and Mercator. A narrow valley between these craters joins Palus Epidemiarum with Mare Nubium, and a rille from the Rimae Ramsden follows the course of this cleft. The small double-walled crater Marth lies at the southern mid-point of this northern extension.
The selenographic
coordinate s of this feature are 32.0° S, 28.2° W, and it is enclosed within a diameter of 286 km.Altimetry data from the Clementinespacecraft shows that this feature slopes downward from west to east, with a height difference of 2 km from end to end.External links
