Minecraft wiki entry for Beach, associated text: The stony shore variant replaces normal beaches in areas with mountainous terrain at low erosion values. They are made entirely of stone, with large layers (stripes) of gravel. They are usually a steep drop into the water below. Stony shores may generate at high enough elevations to have snow on their peaks, even when bordering warm biomes. Waterfalls and lavafalls frequently generate on the sides of stony shores. Unlike normal beaches, turtles cannot spawn here. Buried Treasure can sometimes generate at high altitudes, and can even generate at y-90‌[Bedrock Edition only]. The steep drops into the ocean below makes this variant dangerous, especially if the player is unaware of their surroundings.
