A series of deep holes suddenly appeared in quicksand near Mount Boldi, Indiana, and then mysteriously disappeared into during the day. Last summer, six-year-old Nathan Woeschner during his walking on the sands near Mount Boldi suddenly fell into a deep pit. To save the boy from a hole 4 meters deep, it took rescue team and about three hours of time. Large holes suddenly formed in the sand, forced officials to security close part of the park located on the lake Michigan. Where did these dangerous mysterious depressions come from the sand? Ken Mehne, Park Law Enforcement Representative, said: “We don’t know exactly what is happening there. However, not yet we’ll figure it out – we can’t risk the safety of people. “Geologist Erin Argilan heard the cries of the parents of the boy who fell into the pit during Mount Boldy’s research. “I cried for several days, “said Erin, who on that moment was pregnant and could not help in the rescue a child. “Then I couldn’t help, so today I’ll do everything possible in order to find out the reasons for the appearance of these depressions. ” Other experts are no less interested in Erin. these strange holes in Mount Boldi. Some of the troughs appeared back last year however were not discovered due to sand which managed to fill them. According to scientists, quicksands really exist, although it’s not as dangerous as we used to think. Quicksand is a mixture of sand and water. Its surface looks solid, but will collapse if a heavy object, person or animal gets on it. After liquefaction, this mixture tends to solidify, enveloping and capturing the animal’s feet with wet, heavy sand. There are also dry forms of quicksand. Controlled Laboratory Experiments conditions have shown that artificial sand can completely suck an object however in nature dry quicksand never were observed. To get information about the bottom of the mysterious holes, NPS crews were involved in conjunction with environmental researchers. With radar researchers got a better idea of ​​the big sand dune. They found a layer of soil buried under quick-moving sand, which was previously on the surface of the earth. “This particular the dune has a rather complicated history, “said the researcher Argudan. In this place, sand was used to be mined. in the manufacture of glass, which could lead to the formation of voids in rock formations. Argudan reviewed historical photographs of this areas to determine what has changed since 1930. Trees and the grass that once covered Mount Boldy is now also buried under the sand. These discoveries led researchers to to the conclusion: something is buried under the sandy surface – trees, artificial structures, debris – during the rapid movement of the dune in late 20th century. The humid conditions of spring 2013 may have led to instability of the mountain structure, as a result of which holes on its surface.
