Explosive eruptions produce and disperse fragmental material in a number of different ways. Each process produces a deposit with characteristic features such as thickness, grain size, sorting, and sedimentary features. Here you will be able to view and describe the deposits from the three eruptions that you've already observed, thereby establishing the link between eruption process and the geologic "evidence" one would find in the field.
