Hi Peter, Here is the info I have on the Scotch Cap diary: https://avo.alaska.edu/downloads/reference.php?citid=3422 Clark, M., Villegas, Bob, Stanley, Mike, and Standridge, Ray, 1978, Scotch Cap diary: unpublished personal account, 8 p. These pages were scanned from a notebook of files kept by the late Juergen Kienle. They are an unpublished account of the event. Thank you, Cheryl Hello: My name is Peter Kaufman and I am a writer in Cincinnati, Ohio. I'm writing a book about Scotch Cap on Unimak Island and came across a document on your website. This is entitled "Scotch Cap" diary by Richard E. Clark, and details the 1978 Westdahl eruption. Can you tell me the source of this document? Was it sent to you? I want to give the correct citation in my book endnotes. Thanks, Peter Kaufman pkauf305@gmail.com
