41. This crater has only been slightly worn through impact erosion , and it retains a sharp outer rim and well-defined features. 42. Little remains of the southwestern rim of Parrot, and the other sections of the wall have been worn and smoothed by impact erosion . 43. When viewed from orbit, this appears as a circular crater with an outer rim that has not been significantly worn through impact erosion . 44. This crater is in an intermediate stage of impact erosion , with a worn rim and some craters overlapping the edge and inner wall. 45. The rim of this crater is worn by impact erosion , particularly along the eastern side where a pair of small crater lie along the edge. 46. Although linear, this valley is irregular in shape and has been heavily worn by impact erosion , making it difficult to trace across the surface. 47. The rim of this crater has been heavily worn through impact erosion , leaving an irregular rise that is marked by a number of minor impacts. 48. This crater is a relatively fresh impact, as the formation is well-defined and the rim and interior remain nearly unscathed from impact erosion . 49. This is a heavily worn crater formation with an outer rim that has been rendered into an uneven, somewhat circular range due to impact erosion . 50. The outer rim of Henry has undergone some impact erosion , particularly in the south and southeast where it is overlain by a pair of small craters.
