Breached crater; Breached-rim crater
A fluid-incised gap in a crater rim.
Incisions through crater rims carved by inflows or outflows of water or lava. Crater rim cross-sections and breaches formed by outflowing fluid are often shaped like earthen-dam counterparts, i.e., the crater rim is triangular in cross section and the breach is trapezoidal (Wahl 1998; Coleman and Dinwiddie 2007).
Inlet/inflow/entrance crater breach, inlet channel (Fig. 1): The majority of Martian crater breaches are broadly of this type, although several genetic types are encompassed in the category, including breaches by single head-cut channels; breaches by headward extension of channel or valley networks (Irwin et al. 2005), through crater rims, the breaches themselves often incised by dendritic channel networks; rim breaching by lateral migration of adjacent channels (e.g., Enns et al. 2010); and breaches cut by overtopping flows from surrounding fluid-filled...
