Here is another photo of the 2010 event which appeared on 1st June (or thereabouts) during a tropical storm called Agatha.
Just for comparison, you can see that these events are not unique to Guatemala. Not very far away (on a galactic scale at least) on the Sarisariñama Plateau, Venezuela, there are some older looking sink holes that are about 350m in diameter.
And if you prefer a marine environment . . .
The "Great Blue Hole" is an underwater sink hole in Belize. Would you feel vertigo if you were in that boat going over the edge of the hole?
