Thanks Roger. Gary Wiles (copied here) has been doing a most wonderful inventory of colonies in western Washington. Colonies in the Mt St Helens blast zone have been suggested as likely but, to my knowledge, this might be the first one actually documented. The conditions created by the accumulations of ash/sand would seem to be good for attracting colonization by this species.

Subject: [Tweeters] Bank Swallow Colonies







Someone asked about locations about Bank Swallow Colonies. I came across a large colony on Coldwater Lake up b Mt. St. Helens memorial. It's on an island in the lake.
