The impact of this crater near the edge of the Jura Mountains pushed some material into the Sinus Iridium floor . The rim of this crater is not significantly worn , although there is a small crater along the inner side of the eastern rim . Within the inner wall is a somewhat irregular floor and a small cluster of ridges at the mid-point . Portions of the inner wall have slumped toward the floor along the northern edges . Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Bianchini crater .
