Samples were collected from each layer along a profile parallel to flow lines, as interpreted from tree blow-down directions. The decrease in the mass of sediment of different grain sizes with distance supports a turbulent-gravitational mechanism of suspended sedimentation, and transport within a dilute blast cloud having a density only slightly greater than that of the atmosphere. Traditional sampling strategies would have been unable to yield data suitable to test this settling mechanism hypothesis. This content is PDF only. Please click on the PDF icon to access.
