Four humpbacks in North Pass

We spent some time in our boat and found at least four humpbacks in North Pass, including #2070 aka Barnacles and her calf.  One of the whales spent a lot of time logging at the surface.  It then dove and breached.  Several hours later we came back through the pass and noticed one of the whales logging at the surface again.  After it dove it breached.  I am not sure if it was the same whale that we saw breach earlier in the day.  We have seen a lot of breaching this year.  I am hoping that means the whales are getting the food that they need.
