Hello Patrick, I'm cc'ing Kristi Wallace on this email, who knows more about the Pavlof ash event than I do. As far as I know, we do not expect a visible ash layer in the Alaska Range from the Pavlof eruption - our current furthest ashfall reports come from Togiak. AVO scientists attempted to collect potential Pavlof 2016 ashfall in interior Alaska - ashfall definitely did not occur over Fairbanks. We have a proximal sample of Pavlof 2016 ash from Nelson Lagoon and are currently conducting composition and size analyses of that sample. We have not yet been able to conduct fieldwork at Pavlof, post-eruption, due to continuous poor weather. If you're asking about ash characterizations of other (older) ash layers that might be present in the Alaska Range, Kristi is certainly the right person to ask. Thank you, Cheryl Cameron -------- Patrick Saylor wrote: Hello AVO, My name is Patrick Saylor, I am student at Dartmouth College participating in a field season in Denali National Park this coming June. This field campaign is associated with a larger NSF grant in which an ice core paleoclimate record was recovered from Mt. Hunter in 2013 as a collaboration between Dartmouth College, University of Maine and University of New Hampshire (PIs: Osterberg, Kreutz, Wake). I am curious about the Pavlof eruption, and whether or not it will affect our field logistics and science plans. Questions: 1] Do you expect a visible ash layer over the Denali Massif/Alaska range due to the Pavlof eruption? 2] Are there estimates or ground reports from the range that could provide me with additional information or characterize the ash-fall events in this area in any way? Thank you for your time.
