A couple of items about East Sentinel. Noting that I have not had the privilege to see it erupt since ??the early 1980s or so, I can say this: 1. I'm pretty sure East Sentinel had some eruptive activity this past summer, sometime probably not too long before my arrival in the Park in late August, as I saw signs of washing on the slope uphill, where the trees were already browning. 2. I'm quite certain that the "side vent" described with this activity is/are the same as what I put into my book's 4th Edition as "UNNG-MGG-2 ("Sentinel's Vents")". The eruptions I saw in 2004 and 2005 were independent of anything more than the normal boiling in East Sentinel itself. Scott Bryan In a message dated 11/9/2010 1:13:28 A.M.
