Atmospheric particulate material collected from the stratosphere in plume of the 18 May 1980 eruption of the Mount St. Helens volcano was quite similar in composition to that of ash that fell to the ground in western Washington. However, there were small but significant differences in concentrations of some elements with altitude, indicating that the statospheric material was primarily produced from fresh magma, but fragments of the mountain.
