Transitional Crater (Simple/Complex)
Crater characterized by relatively smooth walls and a floor partly or completely covered by debris slumped from the crater walls. It is a transitional form between a simple bowl-shaped crater and a complex crater with a central uplift (Cintala et al. 1977; Howard 1974; Young 1977).
Note that infilled simple craters and flat-floored pristine complex craters near the simple-to-complex transition diameter may exhibit similar apparent morphologies and may not be distinguished by photogeologic methods (Robbins and Hynek 2012).
