We will be driving from Los Angeles to Death Valley late July 2014 and want to camp at Wildrose campsite. We were planning to drive via Trona but it appears the Trona-Wildrose road may be closed due to strom damage 12 months ago. Is this road still definitely closed? Can the road closed signs be ignored? Can the campground still be accessed by entering Death Valley from the west on the 190 and then turning down Emigrant Canyon road? Is the campsite actually open? We will be driving an SUV.
