Scoria, also called volcanic cinder, is a pyroclastic, highly vesicular, dark-colored volcanic rock formed by ejection from a volcano as a molten blob that cools in the air into discrete grains called clasts. It is riddled with macroscopic ellipsoidal vesicles, gas bubbles that give it a low density, though unlike pumice it typically sinks in water.

Scoria is a dark-colored igneous rock with abundant round bubble-like cavities known as vesicles. It ranges in color from black or dark gray to deep reddish brown.

Two edifices, less than 2.5 kilometres (1.6 mi) wide, flank the 1.3-by-0.5-kilometre-wide (0.81 mi × 0.31 mi) summit crater on its eastern and western side. Basalt, gravel, pumice and scoria crop out in its rim, which is lower on the northern side.

A cinder cone or scoria cone is a steep, conical landform of loose pyroclastic fragments, such as volcanic ash, clinkers, or scoria, that has been built around a volcanic vent.
