Description
Pit craters are circular to elliptical, shallow, steep-sided depressions which lack the elevated rim and ejecta deposits typical of impact craters or lava flows typically associated with calderas (Wyrick et al. 2004). Pit craters commonly have a conical shape, with or without a flat floor (Wyrick et al. 2004). They are sometimes found in alignments (pit crater chains), which in many cases coalesce into linear troughs and are bounded by a graben (Fig. 1). Volcanic pit craters have little or no overflow of their lava lakes (Halliday et al. 2012).
