Mnemonic

From the mountain peak, you spot a sheer cliff dropping straight down. Its exposed face is completely dry and crumbling in the heat. You scramble down and finally reach the shore — a narrow strip where waves crash against the base of that towering, sun-baked rock wall.
Additional thoughts
Picture the vertical stack: mountain on top, cliff in the middle, dry land at the bottom meeting the water. The shore is always where steep, dry land finally meets the sea.
Quick recall
A mountain's cliff face, baked dry, plunges down to the shore.

Details

The keyword for 岸 is shore. It refers to the land along the edge of a body of water, such as a river, lake, or sea. It conveys the idea of a bank or coast where water meets solid ground, often implying a somewhat elevated or steep edge rather than a flat beach.
