Alaska’s most famous bore tide occurs in Turnagain Arm, just outside Anchorage. It climbs up to 6 – 10 feet tall and can reach speeds of 10 to 15 miles per hour. It takes not just a low tide but also about a 27-foot tidal differential (between high and low tide) for a bore to form in Turnagain Arm. https://cutt.ly/prrG1lR
