A reader/friend sent me a link to a part of this report and then I saw it on twitter and was reminded that I wanted to post this to the blog. It is fascinating. it was done for the USGS and is a study of the debris flows in late January of all 3 burn areas in Monterey County, and on the Lightning Complex fires in Santa Cruz. It was published the 2nd of this month.
