Guests on a recent Turnagain Arm Treasures tour witnessed a rare sight that most visitors to Anchorage don't typically see. While driving along the Seward Highway, the group encountered surfers preparing to ride the bore tide. A bore tide, also known as a tidal bore, is a natural phenomenon that occurs when an incoming extra high tide meets an extremely low tide in a large bay with a narrow inlet. This creates a wave that can reach 3 to 6 feet in height and travel the length of Turnagain Arm. Seeing a bore tide is just one of the many unique experiences possible on tour with experienced photo guides at Alaska Photo Treks.
