"View of the south face from less than three miles during the height of the May 18th eruption. Note that steam as well as ash is billowing from the crater and that larger fragments are beginning to fall from the cloud. Rock fragments and pumice that were carried upward along with the ash, rained down in an area that extended 25 to 30 miles to the north and east." (U.S. Dept. of Commerce, 1980, p. 4)
