Check back with the Native museum in Anchorage once it opens fully in season. They have various events, speakers etc. As for kayaking- you could kayak in Whittier then take the train to Anchorage- leaves around 6pm- I think. Would make good use of time since you are disembarking in Whittier. As mentioned- Totem Heritage museum has authenic poles- Saxman are copies. You may want to hire a private guide at Saxman- inquire at the visitor center for their top historian perhaps??
