ISCA 2002 Excursion The ISCA 2002 excursion departs the Anchorage Hilton by motorcoach to the unique town of Whittier. Sights along this scenic drive include the Turnagain Arm of Cook Inlet, the Kenai Mountains, and Portage Valley. Dall sheep and bald eagles are often spotted on the drive. Whittier is located in the Prince William Sound just past the Whittier tunnel, the longest highway tunnel in North America. In Whittier, participants will board a cruise ship and depart on a 2 1/2 hour cruise to visit the Blackstone, Northland, and Beloit Glaciers. Wildlife that may be spotted in the Sound includes whales, seals, porpoises, sea otters, and many migratory birds. Dinner will be served at the glacier's face before returning to port in Whittier and driving back to Anchorage.
