No, not subaqueously. My neice and nephew grew up on a farm in SW Nebraska
in an area known as the sand hills. Geologically about a thousand years ago
Western Nebraska was a desert with dunes. Even in the 30s my former sister
in law tells me that the dunes started moving again and covered some farm
houses. Today the huge sand dunes are covered with grass which stabilizes
them. When it rains hard, the slopes fail and then they bury things. The
following is from the New York Times account of this issue which gives stuff
the Geology article doesn't.
Again, Dr. Loope drew on his experiences in the Nebraska
Sandhills to provide the solution. Before leaving for Mongolia he
had been studying a poorly known phenomenon in which otherwise
stable sand dunes became drenched with water in heavy rains,
triggering sudden debris flows. In talking to residents of the
area he began to hear intriguing stories. In one instance, a
pick-up truck parked at the base of a large sand dune was half
buried by sandflows generated by a heavy July rainstorm. In
another case a barn built on a dune slope was partly filled by a
flow. Such "sand slides" in the Gobi Desert could have trapped
the dinosaurs and other animals that were in the path of the
debris, entombing them until they were uncovered by the
paleontologists.This would account for the extraordinary quality
of the Ukhaa Tolgod fossils and would explain why they are always
found in the sandstones that lack the structured layering caused
by wind action.
That pickup truck was not buried subaqueously. And anyone who has traveled
that part of the country can look and see slump scars on lots of the
Nebraska sand hills. The scenario is reasonable given the analogous
situation in Nebraska.
