Digging large holes on the beach can be a hazard to both humans and wildlife day and night. Sand holes collapse often due to the instability and weight of sand, posing a suffocation risk to anyone in the sand hole. Sand holes create hazards for lifeguards patrolling the beach on ATVs and people walking along the beach. In addition, sand holes can become fatal traps for sea turtles that generally nest on the beach at night. Be sure to fill all sand holes at the end of the day, or, better yet, build an epic sand castle instead!
Stay safe on the beach and look out for others!
