The gravel section of Moose-Wilson Road in Grand Teton National Park is closed today allowing for crews to apply a dustcoat onto the roadway. Traffic will still be able to travel the road from Moose to the Lawrance S. Rockefeller Preserve or to the Death Canyon Trailhead as those destinations are still along the paved portion of the road. The product used for dust abatement is a slurry of magnesium chloride—the same product that is used to treat dirt roads in and around Jackson Hole. This product coats the road surface, but it can also adhere to the undercarriage of vehicles. Therefore, motorists who drive this portion of the Moose-Wilson Road after it reopens on Thursday may want to rinse off their vehicles to eliminate any residue. Park officials say this is the second dust abatement application on that road this summer.
