La Perouse is one of a relatively large number of limb craters that are not often observed and are even harder to identify. La Perouse is limbward of Langrenus in a seldom seen area. At 77 km in diameter it is typical complex crater with terraces, central peak and relatively flat foor. It is a larger version of Kapteyn, another rarely identified crater at bottom left. La Perouse is a fairly fresh crater - although it does have a later impact on its floor - but the Clementine high Sun [http://pdsmaps.wr.usgs.gov/explorer-bin/mapmars4.cgi?WHEREFROM=PZ&VERSION=INTERMEDIATE&DATA_SET_NAME=moon_clementine_bw&PIXEL_TYPE=BIT8&SCALE=pixels/degree&PROJECTION=SINUSOIDAL&RESOLUTION=16&RESAMP_METHOD=NEAREST_NEIGHBOR&BANDS_SELECTED=&FORMAT=JPEG&LONBOX=32&LATBOX=32&GRIDLINE_FREQUENCY=none&STRETCH=AUTO&LAT=-4&LON=75&LINE=512&SAMP=512 view] shows it has no ray system and thus is probably more than a billion years old.
