Humpback from our deck

Observed the tail end of a diving humpback out in Nichols Passage.  I continued to watch for approximately 15 minutes in the hopes of getting a photo, but I did not see it surface again.  I learned later in the day that four humpbacks were cooperatively feeding very close to shore near mountain point.  Perhaps the whale I saw was part of the group?  Sounds like missed a great show at mountain point.
