The road is washing out! 4.4km after you turn left onto a road with a sign reading "Downton Creek" there is a washout. It was passable at the time we went, but it'll only get worse. Furthermore, in Matt Gunn's book, "Scrambles in Southwestern British Columbia", he writes that at the 5.7km mark, from the turn off off Duffey lake road onto the one with the sign "Downton Creek", to go right. This is NOT correct, you should go left! Also, he states the map reference as 92J/8 Duffey Lake, it is actually 92J/9 Shalalth. That last bit of information was taken from the updates page
of his publishing company's website.
