In a Seattle Times report, a document given to the U.S. Army Corps of Engineers warned that Oso was ripe for ‘catastrophic failure.” The document was written by geomorphologist, Daniel Miller, who told The Times, “We’ve known it would happen at some point. We just didn’t know when.” Miller said that he has studied the unstable hills around Oso were the mudslide happened since the 1950s. In 2006, he was shocked to find that, just after a smaller slide in the area, he saw carpenters building news houses along a stretch around directly beneath a dangerous hill.

According to census data, Oso has a population of less than 200 people. The mudslide is believed to have been created by a month of heavy rainfall in the area. Chief Hots had described the mudslide as being more “like quicksand.” The mud was so dense on the night of March 22 that rescue workers had to suspend their search despite being able to hear cries of help.
