The tides in Halibut Cove Alaska can be fierce. The few days I was on the cove, the tides were 28 feet: +24 high and -4 low. Boaters had to time their trips according to the tide charts. As you can see in the photos, there are boats lying in the mud during the low period.
This is low tide.
This is high tide in the same spot.
Another low tide spot.
When the tide is low, the ladders to get to the dock can be extremely steep.
