Terra - obsolete term for bright highland areas Swirl - bright areas typically associated with strong magnetic anomalies Rima - fissure (Latin) or rille (German for groove) Ray craters - craters with prominent 'rays' extending outward Radar bright - radar bright craters are young Pyroclastic - type of rocks of volcanic origin (see Charles Wood's and Maurice Collins's 21 Century Atlas of the Moon). Minor feature - extremely small named craters ![]() Only the NASA and the astronauts of the early Apollo missions invented names with the word Mesa in them, such as Barbara Mesa, Lonesome Mesa, etc. The people of the IAU never used the word Mesa in their official lunar nomenclature. Mesa - According to Wikipedia, a Mesa is an elevated area of land with a flat top, surrounded on all sides by steep cliffs. Lunar Basin - extremely large impact craters Landing site name - at or near Apollo landing site (only the people of the NASA and the astronauts of the early Apollo missions used the word Gulch in their nomenclature for certain lunar surface formations, not the IAU). Sudden intense rainfall upstream may produce flash floods in the bed of the gulch. It may contain a small stream or dry creek bed and is usually larger in size than a gully. Gulch - According to Wikipedia, a Gulch is a deep V-shaped valley formed by erosion. Boulder tracks - narrow grooves left by rolling or sliding rocks and bouldersĬentral peak composition - chemical makeup of crater central peaksĬoncentric crater - small crater with two rims, sort of.ĭark-halo - low-albedo deposits surrounding some cratersįloor Fractured Crater -impact morphology modified by volcanic-related activity
