This crater may host ice-rich deposits within its floor. Though in total shadow when it was imaged here on November 7, 2013, only a portion of the floor is permanently shadowed from the Sun's rays. The crisp rim and well-preserved field of secondary craters surrounding Yoshikawa mean that it is a relatively young crater, and any ice deposits within it must also be relatively young.


Crater image was filtered by the CornerFilter in Mathematica and instead of looking at the dominating crater arch, plethora of 'corners' were unearthed which then each become a note(s) in the melody and chords of the subsequent sonification by MetaSynth, and the Melodic-algorithm midification was performed by Melodyne, both time quantization and pitch were corrected as well:

The resulting Midi file was played twice back to back, by instruments on Logic Pro namely Stratosphere and Anticipation Synthesizer>Soundscape .
