high tide line
Ocean's upper reach
The high tide line is the mark left on a shore at the furthest reach of the tide.
It typically shows as a line of debris—seaweed, driftwood, shells—deposited where the water stopped.
The high tide line matters legally for determining property boundaries and public beach access: The lot extends to the high tide line.
