The tidal bore in Turnagain Arm south of Anchorage can carry surfers for an hour, but it can also be deadly. With the secret now out, authorities are considering how long to allow surfers to catch the wave. The wave, which can reach 10-15 feet high, is a unique phenomenon that attracts surfers seeking an adrenaline rush.

However, the strong currents and unpredictable nature of the wave make it a dangerous activity. Experts recommend wearing a life jacket and having a safety plan in place. The Alaskan Wave Riding experience is a once-in-a-lifetime opportunity that should be approached with caution and respect for the power of nature.
