(A) A bowl-shaped nREC with a diameter, D = 30 m. (B) nREC with diameter, D = 80 m. (C) REC with 190 m diameter, rocks in ejecta and crater cavity, continuous ejecta. Some superposed smaller craters in ejecta. (D) REC with 150 m in diameter; rocks present in ejecta and crater cavity. Superposed craters on ejecta and ejecta is less pronounced. (E) Bottom is fresh REC 170 m in diameter with fresh rim and continuous ejecta with superposed smaller craters. The top is a very degraded REC for comparison.
