2009/365/217 Stratigraphy of My Geologic Past
Well, it looks like layers, but the sequence is out of order.
At the top is my 1989 MS Thesis from Arizona State University, Ash Flow Zones of the Bishop Tuff: Detailed Mapping with Landsat Thematic Mapper. It was written in Word 3 on a Mac Plus, and I have yet to find an old Mac I can run Word 4 (which I bought on eBay) to upgrade it to a version that might open with a modern piece of software.
Like that's a high priority project ;-)
Below that is a box of photos of a small volcanic eruption at Mount St Helens on August 7,1980-- this was unique because a USGS photographer took a time lapse series of photos form which flow velocities could be determine. I spend a year in 1991 on research and writing to co-author a 4 part article in Geology:
"Hydraulics of the August 7,1980, pyroclastic flow at Mount St. Helens, Washington" Geology; November 1991; v. 19; no. 11; p. 1121-1124 (abstract getting a PDF will cost me $35!)
And on bottom is the Bible (then) of Ash-Flow Tuffs (good reading material for sleepless nights) and this is so old there's nothing online but citations.
