Well, I've talked to the two who might know about the explosion at Tabeaud and have come up with no answer. One possibility is that there is some kind of purge valve, but I find that unlikely since the intake for the flume is better than 200 yards away and the intake to the lake is a 1/4 mile or more. The other idea is that it's a volcanic gas "burp" (thanks to Detroit Sports & More). After all, I do live in Volcano and Tabeaud is not all that far away.
I saw it, heard it (not an explosion), and didn't have my camera handy to take a picture of it. So, your guess is as good as mine. The mystery remains.
Countdown to Oregon: I was a little eager last Friday when I said 20 days, it was more like 26 days. Today it's 20 or October 8th.
