Episode narrativeepisode_narrativeMud and debris began flowing onto US Highway 26/89 near milepost 127 in the Snake River Canyon on Saturday morning, May 14, as a result of rapid snowmelt in the area of Double Draw. The Wyoming Department of Transportation closed the highway late that evening as the massive flow became too much to keep up with. The highway through the canyon is the main artery connecting Star Valley and Jackson Hole with over 5,700 vehicles traveling the corridor each day.||The slide covered the roadway at a rate of a couple of feet each hour. By Monday, May 16, debris covered the road to a depth of more than 40 feet and was well over 100 feet wide. The debris flow, eventually estimated at over 2,000 feet in length, deposited approximately 200,000 cubic yards of debris on the road. More debris slipped over the roadway and down a steep embankment to the Snake River. The flow left a trench 30 feet wide and more than 7 feet deep in the road surface. The thoroughfare was opened on Sunday, May 29, following installation of a large culvert to allow water to flow under the road.
