Ash from volcanic activity during the Pleistocene Epoch can often be dated and used as a stratigraphic marker. Ash fresh out of a volcano may be as hot as 1800 degrees Fahrenheit. However the fine material (millimetre-sized ash), which is derived from volcanic glass, rock and crystal particles, can be carried by currents in the eruption column to high above the volcano and pass into the downwind plume to rain out forming ash fall deposits. It's having a bit of a moment in natural skincare right now. Pyroclastic flows are superheated dense mixtures of hot rock fragments or tephra, ash, and gases.
