All true, and highly unusual, mostly in beach sand which has “hollows” in it from water incursion and then dropping down carrying the above sand down creating a gap.
That is a way deeper hole than your typical kid digs with a plastic pail and shovel. Where the heck were the parents?!
Reminds me of the antlion sand trap. How does the insect know the correct angle in making the trap?
“And dry sand can only hold a 33-degree angle, and people dig these holes almost vertically.”
I’d never thought about that. You dig through the dry sand to the wet sand underneath and make vertical walls. Then it dries out, collapses and you are buried.
Poor little girl. What a horrific way to die and the grief of her parents and brother must be unimaginable. A fun family vacation at the beach and this happens.
I have warned my local golf pro of the dangers of sand traps but the refuse to remove them.
Joe Biden will announce a 5 billon dollar sand hold safety initiative tonight .
8,000 new govt jobs will come from it
**when a 5-to-6-foot-deep hole collapsed on her and her 9-year-old brother,***
I remember something similar happening to kids in Japan many years ago.
The operative phrase is “angle of repose.”
