Why it's called a Tidal Bore


The tidal bore is an anomaly of nature which can be observed in Turnagain Bay on the Kenai peninsula. The incoming tide is slowed by the friction of the bay's shallow mud flats. The mass of water increases until it develops enough volume to overcome this resistance. The sudden rush of incoming water can produce a tidal wave of 6 feet. Based on Vinnie's careful research, we found the right place, the right time, and planted ourselves in a front row seat. Unfortunately, the Tidal Bore lived up to its name. Several hours late, a 6 inch wave approached and disappeared. This picture captures the dramatic moment.
