A Rare White Killer Whale Visits SE Alaska
Although the waters of Southeast Alaska are quieter this summer, Captain Dennis, crew and guests aboard the Northern Song were treated to the vision of a lifetime in early August—spotting TI’uk, a rare white killer whale off Cape Bendel. Captain and Crew are always on the lookout for spectacular wildlife and whale viewing and this one is at the top of the list! It’s so rare that the local Petersburg radio station, KFSK, featured it as well. Listen on KFSK.

Updated: The Alaska Sea Adventures sighting of TI’uk has also been featured in the Anchorage Daily News. Read all about it here!

August Newsletter!
Our August Newsletter is published and features more on TI’uk plus trends in luxury yachting and recent sightings of mom and calf whales in Southeast Alaska. Also in the newsletter is a great recipe from Chef Therese for a super simple Blueberry Rhubarb Chutney and some wonderful easy to make artisan rosemary crackers. Schedule updates and news on the 2021 Cheeseman’s trip to the Antarctic. You can read current and archived editions on our website and be sure to sign up for future editions.
