The Tide:
The returning tide was primary danger—it arrived quickly, cut off retreat routes, swept the unwary into deep water. Drowning deaths were regular occurrence among coastal foragers.
The Slippery Rocks:
Seaweed-covered rocks were treacherously slippery—falls resulted in broken bones, head injuries, drowning in shallow water.
The Waves:
Even during low tide, waves could surge unexpectedly—washing foragers off rocks, pulling them into the sea, creating dangerous situations with no warning.
The Cold Water:
Immersion in cold water caused rapid heat loss—even strong swimmers could become incapacitated quickly, losing coordination, strength, consciousness.
